INTRODUCTION

This appendix provides instructions, data sheets, and distress maps for use in visual surveys for the collection of distress information for ACP, JCP, and CRCP surfaces. Visual distress survey procedures have been used in the LTPP program as the primary distress data collection method since 1995. The Distress Identification Manual for the Long-Term Pavement Performance Program is the basis for all distress surveys performed for the LTPP.

During the visual distress survey, safety is the first consideration, as with all field data collection activities. All raters must adhere to the practices and authority of the State or Canadian Province.

EQUIPMENT FOR DISTRESS SURVEYS

The following equipment is necessary for performing field distress surveys of any pavement surface type.

INSTRUCTIONS FOR COMPLETING DISTRESS MAPS

The distress maps show the exact location of each distress type existing on the test section. The distress types and severity levels should be identified by using the Distress Identification Manual. A total of five sheets are used to map; each sheet contains two 15.25-m maps which represent 30.5 m of the test section (with the exception of SPS-6 sections 2 and 5, which are 305 m).

Each test section must be laid out consistently each time a survey is conducted. Sections begin and end at the stations marked on the pavement. Lateral extent of the section, for survey purposes, will vary depending on the existence of longitudinal joints and cracks and the relative position of the lane markings. Figures A1 and A2 illustrate the rules to follow when determining the lateral extent of the section for a distress survey. The lateral extent of the test sections should be consistent with prior distress surveys. On widened PCC sections, the lateral extent of the test section includes the full width (4.3 m) of the slab measured from the centerline longitudinal joint to the shoulder joint. The lateral extent of AC test sections with double yellow lines on the centerline are determined by using the inside yellow line.

Figure A1.  Test Section Limits for Surveys - Asphalt Surface, Illustration of the rules to follow when determining the lateral extent of the section for a distress survey of an asphalt surface.  The drawing shows one lane of a pavement surface as it would be viewed from above with a center line at the top and the edge stripe and shoulder at the bottom, and close-up views of the areas on each side of the lane.  An arrow indicates that the traffic moves toward the right side of the drawing.  Vertical lines and arrows between the center line and the edge stripe indicate the area that should be measured to determine the section width.  Sections begin and end at the stations marked on the pavement.  Lateral extent of the section, for survey purposes, will vary depending on the existence of cracks and the relative position of the lane markings.  When the distance between the edge stripe or center line and an adjacent joint, crack or edge is less than 0.3 m, then the section width should be measured to the pavement break rather than to the lane marking.  The lateral extent of AC test sections with double yellow lines on the centerline is determined by using the inside yellow line.

Figure A2.  Test Section Limits for Surveys - Concrete Surface, Illustration of the rules to follow when determining the lateral extent of the section for a distress survey of a concrete surface.  The drawing shows one lane of a pavement surface as it would be viewed from above with a center line at the top and the edge stripe and shoulder at the bottom, and close-up views of the areas on each side of the lane.  An arrow indicates that the traffic moves toward the right side of the drawing.  Vertical lines and arrows between the center line and the edge stripe indicate the area that should be measured to determine the section width. Sections begin and end at the stations marked on the pavement. Lateral extent of the section, for survey purposes, will vary depending on the existence of longitudinal joints and cracks and the relative position of the lane markings. When the distance between the edge stripe or center line and an adjacent longitudinal joint, crack or edge is less than 0.3 m, then the section width should be measured to the pavement break rather than to the lane marking.  On widened PCC sections, the lateral extent of the test section includes the full width (4.3 m) of the slab measured from the centerline longitudinal joint to the shoulder joint.

Test Section Limits for Surveys—Concrete Surface

To map the test section, place the tape measure on the shoulder adjacent to the test section from Station 0+00 to Station 1+00. It may be necessary to secure the tape onto the pavement with adhesive tape or a heavy object. After the tape is in place, the distresses can be mapped with the longitudinal placement of the distresses read from the tape. The transverse placement and extent of the distresses can be recorded using the additional tape measure. After the first 30.5-m subsection is mapped, the tape measure should be moved to map the second 30.5-m subsection. The process is repeated throughout the test section.

The distresses are drawn on the map at the scaled location using the symbols appropriate to the pavement type. In general, the distress is drawn and is labeled using the distress type number and the severity level (L, M, or H) if applicable. For example, a high severity longitudinal crack in the wheel path of an ACP would be labeled "4aH." An additional symbol is added beside the distress type and severity symbol in cases where the crack or joint is well-sealed. Figures specifying the symbols to be used for each pavement type are presented in the following chapters. In addition, example maps are provided to illustrate properly completed maps.

Any observed distresses that are not described in the Distress Identification Manual should be photographed and described on the comments line of the map sheet. The location and extent of the distress should be shown and labeled on the map. Crack sealant and joint sealant condition is to be mapped only for those distresses indicated in figures A4, A5, and A8. The specific distress types that are not to be included on the maps are to be recorded as follows:

Asphalt Concrete-Surfaced Pavement

If raveling, polished aggregate, or bleeding occur in large areas over the test section, do not map the total extent. Instead, note the location and extent in the space for comments underneath the appropriate map(s). These distresses should be mapped only if they occur in localized areas. The extent of these distresses must be summarized on the data summary sheets.

Jointed Concrete Pavement and Continuously Reinforced Concrete Pavement

If map cracking/scaling, or polished aggregate occur in large areas over the test section, do not map the total extent. Instead, note the location, extent, and severity level if applicable in the space for comments underneath the appropriate map(s). These distresses should be mapped only if they occur in localized areas.

The extent of these distresses must be summarized on the data summary sheets.

SURVEY SHEETS' DATA ELEMENTS

In the common data section appearing in the upper right-hand corner of each of the distress survey data sheets the six-digit SHRP ID (two-digit State code plus four-digit SHRP Section ID) is entered. The date the survey was conducted, the initials of up to three raters, before and after pavement surface temperature readings, and the code indicating whether photographs and/or video tape were obtained at the time of the survey are entered in the appropriate spaces.

INSTRUCTIONS FOR COMPLETING ACP DISTRESS SURVEY SHEETS

Location of the vehicle wheel paths is critical for distinguishing between types of longitudinal cracking in ACP. Figure A3 illustrates the procedure for establishing the location and extent of the wheel paths. Both wheel paths must be drawn and identified on the distress maps. The distresses observed are recorded to scale on map sheets. The individual distresses and severity levels depicted on the map are carefully scaled and summed to arrive at the appropriate quantities (e.g., square meters or number of occurrences) and are then recorded on sheets 1-3. It is important to carefully evaluate the distress map for certain distress types which have multiple methods of measurement because of orientation or location within the section. Longitudinal cracking, in the wheel path or elsewhere, are examples of these. Except where indicated otherwise, entries are made for all distress data elements. If a particular type of distress does not exist on the pavement, enter "0" as a positive indication that the distress was not overlooked in summarizing the map sheets. All data sheets are to be completed in the field prior to departing the site. Symbols to be used for mapping ACP sections are contained in figure A4, and an example mapped section is shown in figure A5.

Figure A3.  Locating Wheel Paths in Asphalt Concrete-Surfaced Pavements, Illustration of the procedure to follow for establishing the location and extent of the wheel paths in an asphalt concrete-surfaced pavement.  The drawing shows one lane of a pavement surface as it would be viewed from above with a center line at the top and the edge stripe and shoulder at the bottom.  An arrow indicates that the traffic moves toward the right side of the drawing.  Vertical lines and arrows indicate the area that should be measured to determine wheel path location. The default values indicated are: the width of each wheel path is 0.76 m, the width between the edge stripe and the center of the outer wheel path is 0.76 m, and the width between the edge stripe and the center of the inner wheel path is 2.9 m.  Wheel paths are assumed to have the width and location as shown, except where texture and color differences and/or observed traffic characteristics clearly define the actual location and widths.  Location and width must be recorded on distress maps.

Figure A4.  Distress Map Symbols for Asphalt Concrete-Surfaced Pavements, Illustration specifying the distress map symbols to be used when completing distress maps for asphalt concrete-surfaced pavements.  Symbols to be drawn on the completed distress maps are indicated for 13 of the 15 distress types: fatigue cracking, block cracking, edge cracking, longitudinal cracking, reflection cracking at joints, transverse cracking, patch/patch deterioration, potholes, shoving, bleeding, polished aggregate, raveling, and water bleeding and pumping.  The 2 other distress types, rutting and lane-to-shoulder dropoff, are not to be drawn on the completed distress maps, and no symbols are provided.  Severity levels of L (low), M (medium), and H (high) should be included on the maps for fatigue cracking, block cracking, edge cracking, longitudinal cracking, transverse cracking, patch/patch deterioration, and potholes.  Also, the presence of a seal (S) should be recorded on the map for block, longitudinal, and transverse cracking.  Other information is indicated that is not included on completed distress maps, but is needed for completion of the associated distress sheet.  These are: (1) distress areas should be measured in square meters for fatigue cracking, block cracking, patch/patch deterioration, potholes, shoving, bleeding, polished aggregate, and raveling; (2) distress areas should be measured in meters for edge cracking, longitudinal cracking, transverse cracking, and water bleeding and pumping; (3) the number of cracks should be recorded for transverse cracking; and (4) the number of occurrences should be recorded for patch/patch deterioration and water bleeding and pumping.  In addition, reflection cracking at joints and lane-to-shoulder dropoff are not measured in LTPP surveys.

The distress map shows the first 30.5 m length of one lane split into two sections; the top portion of the map shows the first 15.25 m (50 ft), and the bottom portion shows the next 15.25 m (50 ft).  The lane is divided by grid markings and there are  marked indicators of length and width at each meter, half meter, and quarter meter.  The width of the lane is 5 m, and the wheel path locations are mapped with straight longitudinal lines.  Various distress symbols, some with severity levels, are drawn at different places on the grid that correspond to the actual location of the distress type.

Description of Data Sheet 1

This data sheet provides space for recording measured values for the distress types identified in the left column. The units of measurement for each of the distress types are also identified in the left column. The extent of the measured distress for each particular level of severity is entered in the severity level columns identified as low, moderate, or high. Enter "0" for any distress types and/or severity levels not found.

Description of Data Sheet 2

This sheet is a continuation of the distress survey data recorded on sheet 1 and is completed as described under data sheet 1. In addition, space is provided to list "Other" distress types found on the test section but not listed on data sheets 1 or 2.

Description of Data Sheet 3

This data sheet provides space to record rutting (using a straight edge 1.2 m long). Manual rutting measurements using a straight edge are only taken for visual surveys conducted on SPS-3 experiment sections. Measurements are taken at the beginning of the test section and at 15.25 m intervals. There should be a total of 11 measurements in each wheel path, for a total of 22 measurements on each test section.

INSTRUCTIONS FOR COMPLETING JCP DATA SHEETS

The distresses observed are recorded to scale on map sheets. This information is reduced by the rater in the field to summarize the results, which are then recorded on sheets 4-7. Except where indicated otherwise, entries are made for all distress data elements. If a particular type of distress does not exist on the pavement, enter "0" as a positive indication that the distress was not overlooked in summarizing the map sheets. Symbols to be used for mapping distresses in JCP sections are shown in figure A6, and an example mapped section is presented in figure A7.

Description of Data Sheet 4

This data sheet provides space for recording measured values for the distress types identified in the left column. The units of measurement for each of the distress types are also identified in the left column. The extent of the measured distress for each particular level of severity is entered in the severity level columns identified as low, moderate, or high. Enter "0" for any distress types and/or severity levels not found. The distress types and severity levels should be identified by using the Distress Identification Manual.

Description of Data Sheet 5

This sheet is a continuation of the distress survey data recorded on sheet 4 and is completed as described under data sheet 4. In addition, space is provided to list "Other" distress types found on the test section but not listed on data sheets 4 or 5.

Description of Data Sheet 6

This data sheet provides space to record faulting information for each transverse joint and transverse crack. Distance from the beginning of the section, and faulting measurements made at two transverse locations, are recorded. The transverse locations are 0.3 m and 0.75 m from the outside edge of the slab. For widened lanes, measure 0.3 m from the edge of the slab and 0.75 m from the outside edge of the lane edge stripe. At each location, three measurements are made, but only the approximate average of the readings is recorded to the nearest millimeter.

Although no field is provided in the space to the left of the entry for measured faulting, there is room for a negative sign when negative faulting is observed. If the "approach" slab is higher than the "departure" slab, a positive sign is assumed, but no entry is required. If the "approach" slab is lower, a negative sign is entered.

Figure A6.  Distress Map Symbols for Jointed Concrete Pavements, Illustration specifying the distress map symbols to be used when completing distress maps for jointed concrete pavements.  Symbols to be drawn on the completed distress maps are indicated for 15 of the 18 distress types: corner breaks, durability (D) cracking, longitudinal cracking, transverse cracking, joint seal damage of transverse joints, joint seal damage of longitudinal joints, spalling of longitudinal joints, spalling of transverse joints, map cracking, scaling, polished aggregate, popouts, blowups, patch/patch deterioration, and water bleeding and pumping.  The 3 other distress types, faulting of transverse joints and cracks, lane-to-shoulder dropoff, and lane-to-shoulder separation, are not to be drawn on the completed distress maps, and no symbols are provided.  Severity levels of L (low), M (medium), and H (high) should be included on the maps for corner breaks, durability (D) cracking, longitudinal cracking, transverse cracking, joint seal damage of transverse joints, spalling of longitudinal joints, spalling of transverse joints, and patch/patch deterioration.  Also, the presence of a seal (S) should be recorded on the map for longitudinal cracking, and the type of patch, F (flexible) or R (rigid), should be recorded on the map for patch/patch deterioration.  Other information is indicated that is not included on completed distress maps, but is needed for completion of the associated distress sheet.  These are: (1) distress areas should be measured in square meters for durability (D) cracking, map cracking, scaling, polished aggregate, and patch/patch deterioration; (2) distress areas should be measured in meters for longitudinal cracking, transverse cracking, joint seal damage of longitudinal joints, spalling of longitudinal joints, spalling of transverse joints,  and water bleeding and pumping; (3) the number of cracks should be recorded for corner breaks and transverse cracking; (4) the number of occurrences should be recorded for joint seal damage of transverse joints, popouts, blowups, patch/patch deterioration and water bleeding and pumping; (5) the number of  joints should be recorded for spalling of transverse joints; and (6) the number of affected slabs should be recorded for durability (D) cracking.  In addition, popouts are not measured in LTPP surveys.

Description of Data Sheet 7

This sheet is used to record lane-to-shoulder dropoff and lane-to-shoulder separation. Lane-to-shoulder dropoff is measured as the difference in elevation, to the nearest 1 mm, between the pavement surface and the adjacent shoulder surface. Measurements are taken at the beginning of the test section and at 15.25-m intervals (a total of 11 measurements) at the lane/shoulder interface or joint. Lane-to-shoulder dropoff typically occurs when the outside shoulder settles. However, heave of the shoulder may occur due to frost action or swelling soil. If heave of the shoulder is present, it should be recorded as a negative value. At each point where there is no lane-to-shoulder dropoff, enter "0."

Lane-to-shoulder separation is measured as the width of the joint (to the nearest 1 mm) between the outside lane and the adjacent shoulder surface. Measurements are taken at the beginning of the test section and at 15.25-m intervals (a total of 11 measurements). At each point where there is no lane-to-shoulder separation, enter "0." When the surveyor is unable to take a measurement due to an anomaly such as sealant or patch material, a null value ("N") should be recorded and entered into the database.

Example Map of First 30.5 m of a Jointed Concrete Pavement Section, Illustration of an example distress map using distress map symbols of the first 30.5 m of a jointed concrete pavement section.  The distress map shows the first 30.5 m length of one lane split into two sections; the top portion of the map shows the first 15.25 m (50 ft), and the bottom portion shows the next 15.25 m (50 ft).  The lane is divided by grid markings and there are  marked indicators of length and width at each meter, half meter, and quarter meter.  The width of the lane is 5 m, and the pavement joints are mapped with bold straight lines.  Various distress symbols, some with severity levels, are drawn at different places on the grid that correspond to the actual location of the distress type.

INSTRUCTIONS FOR COMPLETING CRCP DATA SHEETS

The results of distress surveys on CRCP surfaces are recorded on sheets 8-10. Except where indicated otherwise, entries are made for all distress data elements. If a particular type of distress does not exist on the pavement, enter "0" as a positive indication that the distress was not overlooked in summarizing the map sheets. All data sheets are to be completed in the field prior to departing the site. Symbols to be used for mapping CRCP distresses are contained in figure A8 and an example mapped section is presented in figure A9.

Figure A8.  Distress Map Symbols for Continuously Reinforced Concrete Pavements, Illustration specifying the distress map symbols to be used when completing distress maps for continuously reinforced concrete pavements.  Symbols to be drawn on the completed distress maps are indicated for 14 of the 16 distress types: durability (D) cracking, longitudinal cracking, transverse cracking, map cracking, scaling, polished aggregate, popouts, blowups, transverse construction joint deterioration, patch/patch deterioration, punchouts, spalling of longitudinal joints, water bleeding and pumping, and longitudinal joint seal damage.  The 2 other distress types, lane-to-shoulder dropoff, and lane-to-shoulder separation, are not to be drawn on the completed distress maps, and no symbols are provided.  Severity levels of L (low), M (medium), and H (high) should be included on the maps for durability (D) cracking, longitudinal cracking, transverse cracking, transverse construction joint deterioration, patch/patch deterioration, punchouts, and spalling of longitudinal joints.  Also, the presence of a seal (S) should be recorded on the map for longitudinal cracking, and the type of patch, F (flexible) or R (rigid), should be recorded on the map for patch/patch deterioration.  Other information is indicated that is not included on completed distress maps, but is needed for completion of the associated distress sheet.  These are: (1) distress areas should be measured in square meters for durability (D) cracking, map cracking, scaling, polished aggregate, and patch/patch deterioration; (2) distress areas should be measured in meters for longitudinal cracking, transverse cracking, spalling of longitudinal joints, water bleeding and pumping, and longitudinal joint seal damage; (3) the number of cracks should be recorded for transverse cracking; (4) the number of occurrences should be recorded for popouts, blowups, transverse construction joint deterioration, patch/patch deterioration, punchouts, and water bleeding and pumping; and (5) the number of affected transverse cracks should be recorded for durability (D) cracking. In addition, popouts are not measured in LTPP surveys.

Description of Data Sheet 8

This data sheet provides space for recording measured values for the distress types identified in the left column. The units of measurement for each of the distress types are also identified in the left column. The extent of the measured distress for each particular level of severity is entered in the severity level columns identified as low, moderate, or high, except as indicated on the form. Enter "0" for any distress types and/or severity levels not found. The distress types and severity levels should be identified by using the Distress Identification Manual.

Description of Data Sheet 9

This sheet is a continuation of the distress survey data recorded on sheet 8 and is completed as described under data sheet 9. In addition, space is provided to list "Other" distress types found on the test section but not listed on data sheets 8 or 9.

Example Map of First 30.5 m of a Continuously Reinforced Concrete Pavement Section, Illustration of an example distress map using distress map symbols of the first 30.5 m of a  continuously reinforced concrete pavement section. The distress map shows the first 30.5 m length of one lane split into two sections; the top portion of the map shows the first 15.25 m (50 ft), and the bottom portion shows the next 15.25 m (50 ft).  The lane is divided by grid markings and there are  marked indicators of length and width at each meter, half meter, and quarter meter.  The width of the lane is 5 m, and the pavement joints are mapped with bold straight lines.  Various distress symbols, some with severity levels, are drawn at different places on the grid that correspond to the actual location of the distress type. There are also comments on the map noting that the lane width is 4 m and that there is a construction joint at Station 0 + 27.

Description of Data Sheet 10

This data sheet provides space to record lane-to-shoulder dropoff and lane-to-shoulder separation. Measurements are taken at the beginning of the test section and at 15.25-m intervals (a total of 11 measurements for each distress) at the lane/shoulder interface or joint.

Lane-to-shoulder dropoff is measured as the difference in elevation (to the nearest 1 mm) between the pavement surface and the adjacent shoulder surface. Lane-to-shoulder dropoff typically occurs when the outside shoulder settles. However, heave of the shoulder may occur due to frost action or swelling soil. If heave of the shoulder is present, it should be recorded as a negative (-) value.

Lane-to-shoulder separation is measured as the width of the joint (to the nearest 1 mm) between the outside lane and the adjacent shoulder surface.

When the surveyor is unable to take a measurement due to an anomaly such as a sealant or patch material, a null value ("N") is recorded and entered into the database.

At each point where there is no lane-to-shoulder dropoff or lane-to-shoulder separation, enter "0."

 

Example Survey Maps and Completed Sheets

This part of the appendix shows completed maps and survey forms for a JCP 60 m in length. The rater uses the definitions from the Distress Identification Manual and the symbols from this appendix when mapping the section. The rater then quantifies each distress (and severity levels for the appropriate distresses) on the map. The rater then uses the right margin of the map sheets to tally the quantities of each distress type. This method is required because it simplifies totaling the various distress types, and reduces errors. The rater then uses the tallies from each map sheet to add the distress quantities. The section totals are entered in the left margin of the first map sheet.

The rater then writes in the totals in the appropriate blanks on the survey forms. All blanks are filled in. Zeros are entered if no distress was found. These forms provide a summary of the distresses found in the JCP section.

Example Survey, Page 100, Illustration of an example completed distress map of the first 30 m in length for a 60-m jointed concrete pavement using the definitions and symbols specified in appendix A.  The distress map shows the first 30.5 m length of one lane split into two sections; the top portion of the map shows the first 15.25 m (50 ft), and the bottom portion shows the next 15.25 m (50 ft).  The lane is divided by grid markings and there are  marked indicators of length and width at each meter, half meter, and quarter meter.  The width of the lane is 5 m, and the pavement joints are mapped with bold straight lines.  Various distress symbols, some with severity levels, are drawn at different places on the grid that correspond to the actual location of the distress type.  The rater then uses the right margin of the map sheet to list the quantities of each distress type on the sheet.  The rater then uses the counts from all the map sheets for the 60-m section to add up the total quantity of each distress type.  The section totals are entered in the left margin of this first map sheet.

 

Example Survey, Page 101, Illustration of an example completed distress map of the last 30 m in length for a 60-m jointed concrete pavement using the definitions and symbols specified in appendix A.  The distress map shows the last 30.5 m length of one lane split into two sections; the top portion of the map shows the first 15.25 m (50 ft), and the bottom portion shows the next 15.25 m (50 ft).  The lane is divided by grid markings and there are  marked indicators of length and width at each meter, half meter, and quarter meter.  The width of the lane is 5 m, and the pavement joints are mapped with bold straight lines.  Various distress symbols, some with severity levels, are drawn at different places on the grid that correspond to the actual location of the distress type.  The rater then uses the right margin of the map sheet to list the quantities of each distress type on the sheet.  The rater then uses the counts from all the map sheets for the 60-m section to add up the total quantity of each distress type.  The section totals are entered in the left margin of this first map sheet; because this is the second map sheet, the left margin is left blank.
