Long-Term Pavement Performance Inventory Data Collection
Guide
Appendix A. Standard Codes
Many different types of data are collected on test sections
studies as part of the Long-Term Pavement Performance (LTPP)
program. This document provides the guidelines necessary for
collecting inventory data on these sections. Inventory data include
those necessary to: 1) identify the test section, 2) describe the
geometric details of its construction and the material properties
of its structural constituents, and 3) identify construction costs
and costs of subsequent maintenance and repair before the long-term
monitoring (LTM) effort. Table 1 provides a general list of
inventory data elements.
All of these data, with the exception of certain material
properties such as subgrade strength and moisture content that
change over time or environment, should remain constant throughout
the monitoring period of each test section or project unless the
pavement is resurfaced or rehabilitated during the period. In
either case, the test section becomes for practical purposes a new
pavement structure with new surface conditions, so the basic
inventory data must be revised to describe these new conditions,
while the original data is retained for reference in long-term cost
analyses and studies of the effects of rehabilitation on
deterioration rates. The additional rehabilitation data elements
recommended for collection in the event this occurs during the
monitoring period are discussed in the Maintenance and
Rehabilitation Data Collection Guide.
This document provides data sheets and instructions to collect
inventory data for the LTPP program. The inventory data sheets
appear in numerical sequence at the end of this document.
The inventory data sheets have been taken from the original
Long-Term Monitoring Data Collection Guide and modified to
reflect evolution in planning for LTM of pavements. This was done
partially to maintain some consistency with the LTM pilot study
databases, but primarily to take advantage of the work already
accomplished for the Federal Highway Administration (FHWA) during
the LTM studies, and during studies for the National Cooperative
Highway Research Program (NCHRP) Project 1-19.
The data sheets allow collection of detailed information on the
variability of materials and layer thicknesses, because this
variability is known to contribute heavily to pavement
deterioration. Replicate test data is often unavailable, so single
test results in these cases should be entered as the mean and other
values left blank. However, whenever possible, data on variability
should be obtained.
Data collected for a General Pavement Studies (GPS) test section
should pertain to the original construction of the section or the
most recent rehabilitation/reconstruction. The data sheets required
for each GPS test section will depend on the type of materials
contained in the structure of that test section. Sheets 1, 2, 3,
and 4 are required for every GPS test section. Sheet 3 indicates
the numbers of the additional required data sheets for each
material type present in the pavement structure. Sheet 1A is
required for every GPS test section where measurements are made
with a global positioning system receiver.

General Pavement Studies
(01) Asphalt Concrete Pavement with Granular Base
Acceptable pavements for this study include a dense-graded HMAC
surface layer, with or without other HMAC layers, placed over
untreated granular base. One or more subbase layers may also be
present, but are not required. A treated subgrade is classified as
a subbase layer. Full depth AC pavements—defined as an HMAC surface
layer combined with one or more subsurface HMAC layers beneath the
surface layer with a minimum total HMAC thickness of 152 mm (6
inches) placed directly upon a treated or untreated subgrade—are
also allowed in this study. Two or more consecutive lifts of the
same mixture design are to be treated as one layer.
Seal coats or porous friction courses are allowed on the
surface, but not in combination. For example, a porous friction
course placed over a seal coat is not acceptable. Seal coats are
permissible on top of granular layers. At least one layer of
dense-graded HMAC is required, regardless of the existence of seal
coats or porous friction courses.
(02) Asphalt Concrete Pavement with Bound Base
Acceptable pavements for this study include a dense-graded HMAC
surface layer with or without other HMAC layers, placed over a
bound base layer. To properly account for a variety of bound base
types in the sampling design, two classifications of binder types,
bituminous and nonbituminous, are defined as factor levels.
Bituminous binders include asphalt cements, cutbacks, emulsions,
and road tars. Nonbituminous binders include all hydraulic cements
(those which harden by a chemical reaction with water and are
capable of hardening under water), lime, fly ashes, and natural
pozzolans, or combinations thereof. Stabilized bases with lower
quality materials such as sand asphalt or soil cement are also
allowed. Stabilization practices of primary concern for this study
are those in which the structural characteristics of the material
are improved due to the cementing action of the stabilizing agent.
Thus, the description of the study actually refers to treatments
improving the structural properties of the base materials. Two or
more consecutive lifts of the same mixture design are to be treated
as one layer. One or more subbase layers may be present but are not
required.
Seal coats or porous friction courses are permitted on the
surface but not in combination. For example, a porous friction
course placed over a seal coat is not acceptable. Project selection
is often—to those constructed on both fine and coarse
subgrades.
(03) Jointed Plain Concrete Pavement—JPCP
Acceptable pavements for this study include a jointed,
unreinforced PCC slab placed over an untreated granular base, HMAC,
or stabilized base. One or more subbase layers may also be present,
but are not required. The joints may have either no load transfer
devices or smooth dowel bars. A seal coat above a granular base
layer is permissible. Jointed slabs with load transfer devices
other than dowel bars, and pavements placed directly upon a treated
or untreated subgrade also are not acceptable.
(04) Jointed Reinforced Concrete Pavement—JRCP
Acceptable projects include jointed reinforced PCC pavements
with doweled joints spaced between 66 and 213 m (20 and 65 ft). The
slab may rest directly on a base layer or on unstabilized
coarse-grained subgrade. A base layer and one or more subbase
layers may exist, but are not required. A seal coat is also
permissible over a granular base layer. JRCP placed directly over a
fine-grained soil/aggregate layer or a fine-grained subgrade will
not be considered for this study. JRCPs without load transfer
devices or using devices other than smooth dowel bars at the joints
are not acceptable.
(05) Continuously Reinforced Concrete Pavement—CRCP
Acceptable projects include continuously reinforced PCC
pavements placed directly over a base layer or over unstabilized
coarse-grained subgrade. One or more subbase layers can exist but
are not required. A seal coat (prime coat) is permissible just
above a granular base layer. The placement of CRCPs directly over a
fine-grained soil/aggregate layer or a fine-grained subgrade is not
acceptable for this study.
(06) AC Overlay of AC Pavement
Pavements in the GPS-6A, 6B, 6C, 6D, and 6S experiments include
a dense-graded HMAC surface layer, with or without other HMAC
layers, placed over an existing AC pavement.
The designation 6A refers to those sections that were overlaid
before acceptance in the GPS program.
The 6B, 6C, 6D, and 6S designations refer to LTPP sections on
which an overlay was placed after the section had been accepted
into the LTPP program.
Seal coats or porous friction courses are allowed, but not in
combination. Fabric interlayers and stress-absorbing membrane
interlayers (SAMI) are permitted between the original surface and
the overlay. The total thickness of HMAC used in the overlay is
required to be at least 25.4 mm (1.0 inch).
(07) AC Overlay of Concrete Pavement
Pavements classified in the GPS-7A, 7B, 7C, 7D, 7F, 7R, and 7S
experiments primarily consist of JPCP, JRCP, and CRCP pavements in
which a dense-graded HMAC surface layer with or without other HMAC
surface layers was constructed.
The exception is the 7R classification that has been added to
account for PCC pavement test sections rehabilitated using Concrete
Pavement Restoration (CPR) techniques. (To date, no test sections
have been classified in the 7R category.)
The designation 7A refers to sections that were overlaid before
acceptance in the GPS program. The 7B, 7C, 7D, 7F, and 7S
designation refers to those test sections over which an overlay was
placed after the section had been accepted into the LTPP
program.
The PCC slab may rest upon a combination of the base and/or
subbase layers. The existing concrete slab can also be placed
directly over lime or cement-treated fine or coarse-grained
subbase, or over untreated coarse-grained subgrade soil. Slabs
placed directly over untreated fine-grained subgrade are not
acceptable.
Seal coats or porous friction courses are permissible but not
allowed in combination. Fabric interlayers and SAMIs are acceptable
when placed between the original surface (concrete) and the
overlay. Overlaid pavements involving aggregate interlayers and
open-graded AC interlayers are not included in this study. The
total thickness of HMAC used in the overlay is required to be at
least 38 mm (1.5 inches).
(09) Unbonded JCP Overlays of Concrete Pavement
Acceptable projects for this study include unbonded JPCP, JRCP,
or CRCP overlays with a thickness of 129 mm (5 inches) or more
placed over an existing JPCP, JRCP, or CRCP pavement. An interlayer
used to prevent bonding of the existing and the overlay slabs is
required. The overlaid concrete pavement can rest on a base and/or
a subbase or directly on the subgrade.
Specific Pavement Studies
(01) Structural Factors for Flexible Pavements
The experiment on Strategic Study of Structural Factors for
Flexible Pavements (SPS-1) examines the performance of specific
HMAC-surfaced pavement structural factors under different
environmental conditions. Pavements within SPS-1 must start with
either the original construction of the entire pavement structure
or removal and complete reconstruction of an existing pavement. The
pavement structural factors included in this experiment are
in-pavement drainage layer, surface thickness, base type, and base
thickness. The experiment design stipulates a traffic loading level
in the study lane in excess of 100,000-80-kN (18-kip) equivalent
single axle loads (ESAL) per year. The combination of the study
factors in this experiment result in 24 different pavement
structures. The experiment is designed using a fractional factorial
approach to enhance implementation practicality; permitting the
construction of 12 test sections at one site and the construction
of a complementary set of 12 test sections at another site within
the same climatic region on a similar subgrade type.
(02) Structural Factors for Rigid Pavements
The experiment on Strategic Study of Structural Factors for
Rigid Pavements (SPS-2) examines the performance of specific JPCP
structural factors under different environmental conditions.
Pavements within SPS-2 must start with either the original
construction of the entire pavement structure or removal and
complete reconstruction of an existing pavement. The pavement
structural factors included in this experiment are in-pavement
drainage layer, PCC surface thickness, base type, PCC flexural
strength, and lane width. The experiment requires that all test
sections be constructed with perpendicular doweled joints at 4.9-m
(15-ft) spacing and stipulate a traffic loading level in the lane
in excess of 200,000 ESAL/year. The experiment is designed using a
fractional factorial approach to enhance implementation
practicality; permitting the construction of twelve test sections
at one site and the construction of a complementary set of twelve
test sections at another site within the same climatic region on a
similar subgrade type.
(03) Preventive Maintenance Effectiveness of Flexible
Pavements
The experiment on Preventive Maintenance Effectiveness of
Flexible Pavements (SPS-3) examines the performance of four
preventive maintenance treatments (cracking seal, chip seal, slurry
seal, and thin overlay) on AC-surfaced pavement sections within the
four climatic regions, on the two classes of subgrade soil. The
experimental design stipulates that the effectiveness of each of
the four treatments be evaluated independently. The effectiveness
of combinations of treatments is not considered. Therefore, each
site includes four treated test sections in addition to a control
section. In most cases, the control (or "do nothing") section is
classified as a GPS test section.
(04) Preventive Maintenance Effectiveness of Jointed
Concrete Pavements
The experiment on Preventive Maintenance Effectiveness of
Jointed Concrete Pavements (SPS-4) was designed to study the
effects of crack/joint sealing and undersealing on jointed PCC
pavement structures. Both JRCP and JPCP are included in the study.
Undersealing is included as an optional factor and is only
performed on a section for which the need for undersealing is
indicated. The experiment design stipulates that the effectiveness
of each of the two treatments be evaluated independently. The
effectiveness of combinations of treatments is not considered. Each
test site includes two treated test sections in addition to a
control section. The treatment sections on joint/crack seal test
sites consist of one section in which all joints have no sealant,
and one in which a water tight seal is maintained on all cracks and
joints.
(05) Rehabilitation of Asphalt Concrete Pavements
The experiment on Rehabilitation of Asphalt Concrete Pavements
(SPS-5) examines the performance of eight combinations of AC
overlays on existing AC-surfaced pavements. The rehabilitation
treatment factors included in the study are intensity of surface
preparation, recycled versus virgin AC overlay mixture, and overlay
thickness. The experiment design includes all four climatic regions
and conditions of existing pavement. The experiment design
stipulates a traffic loading level in the study lane in excess of
100,000 ESALs/year.
(06) Rehabilitation of Jointed Portland Cement Concrete
Pavements
The experiment on Rehabilitation of Jointed Portland Cement
Concrete Pavements (SPS-6) examines the performance of seven
rehabilitation treatment options as a function of climatic region,
type of pavement (plain and reinforced), and condition of existing
pavement. The rehabilitation methods include surface preparation (a
limited preparation and full CPR) with a 102-mm (4-inch) thick AC
overlay or without an overlay, crack/break and seat with two AC
overlay thicknesses of 102 and 203 mm (4 and 8 inches), and limited
surface preparation with a 102-mm (4-inch) thick AC overlay with
sawed and sealed joints.
(07) Bonded Concrete Overlays of Concrete Pavements
The experiment on Bonded Concrete Overlays on Concrete Pavements
(SPS-7) examines the performance of eight combinations of bonded
PCC treatment alternatives as a function of climatic region,
pavement type (jointed and continuously reinforced), and condition
of existing pavement. The rehabilitation treatment factors include
combinations of surface preparation methods (cold milling plus sand
blasting and shot blasting), bonding agents (neat cement grout or
none), and overlay thickness (76 and 127 mm (3 and 5 inches)). The
experiment design stipulates a traffic loading level in the study
lane in excess of 200,000 ESAL/year.
(08) Environmental Effects in the Absence of Heavy
Loads
The experiment on Environmental Effects in the Absence of Heavy
Loads (SPS-8) examines the effect of climatic factors in the four
environmental regions, subgrade type (frost-susceptible, expansive,
fine, and coarse) on pavement sections incorporating flexible and
rigid pavement designs that are subjected to limited traffic
loading. The experiment design requires either two flexible
pavement structures or two rigid pavement structures to be
constructed at each site. The two flexible pavement sections
consist of a 102-mm (4-inch) AC surface on 102-mm (8-inch) thick
untreated granular base, and a 178-mm (7-inch) AC surface over a
305-mm (12-inch) thick granular base. The two rigid pavement test
sections consist of doweled JPCP with PCC surface thicknesses of
203 mm (8 inches) and 279 mm (11 inches) PCC over a 152-mm (6-inch)
thick dense-graded granular base. The pavement structures included
in this study match pavement structures included in the SPS-1 and
SPS-2 experiments. The experiment design stipulates that traffic
volume in the study lane be at least 100 vehicles per day but not
more than 10,000 ESAL/year. The flexible and rigid pavement
sections may be constructed at the same site or at different
sites.
(09) Validation of SHRP Asphalt Specifications and Mix
Design
The SPS-9P pilot effort was launched at the end of the SHRP with
the objective of gaining experience in implementing the
Superpave® specifications. Test sections classified as
SPS-9P were constructed using a very limited set of guidelines. In
some instances, specifications were based on interim Superpave
specifications that were changed at a later date. Many of the test
sections were constructed before material sampling and testing
guidelines were established.
The SPS-9A experiment, Superpave Asphalt Binder Study, requires
construction of a minimum of two test sections at each project
site. Construction may include new construction, reconstruction, or
overlay. The minimum test sections consist of: 1) Highway agencies'
standard mix, 2) Superpave Level 1 designed standard mix, and 3)
Superpave mix with alternate binder grade either higher or lower
than the specified Superpave binder. The minimum of two test
sections at some sites results from the agency's declaration that
the Superpave test section is the same as the standard agency
mixture. This experiment will provide the opportunity to evaluate
and improve the practical aspects of implementing the Superpave mix
design through a hands-on field trial by interested highway
agencies. It will also make it possible to compare the performance
of the Superpave mixes and mixes designed with highway agencies'
current asphalt specifications, asphalt-aggregate specifications,
and mix design procedures. In addition, there will be an
opportunity to test the sensitivity of the Superpave asphalt binder
specifications relative to low temperature cracking, fatigue, and
permanent deformation distress factors.
