Long-Term Pavement Performance Ohio SPS-1 and SPS-2 Dynamic Load Response Data Processing

APPENDIX B. SENSOR STATUS OF THE 23 OHIO SPS-1 DLR TESTS

Appendix B shows the instrumentation layout in plan and profile view as well as the pavement layer structure in profile view with sensor status (good, maybe, and not good) for the 23 Ohio SPS-1 DLR test sections.

For figure 27 through 49, sensor colors represent the status of a sensor based on QC results, where green represents good, orange represents maybe, and red represents not good. The sensors with color combinations of more than one color represent status in combination. For example, if a sensor color is in a combination of green and orange, the status of the sensor is a combination of good and maybe.

This illustration shows the instrumentation layout in plan and profile views as well as the pavement layer structure in profile view for test section 390102 Ohio Specific Pavement Studies-1 test J2A, which had 16 test runs. A total of 12 sensors are indicated. The plan view in the top portion of the figure shows 12 sensors in a 22-ft horizontal row on the pavement wheelpath a short distance from the pavement edge. From left to right, the sensors are: two single-layer deflectometers, six alternating transverse and longitudinal strain gauges, two pressure cells, and two additional single-layer deflectometers. The single-layer deflectometers are the peaks of four linear variable differential transformers (LVDTs). The profile view in the bottom portion of the figure shows the four LVDTs extending downward through the pavement and pavement base layer, the six strain gauges embedded in the pavement, and two pressure cells, which are not in the plan view, embedded just below the pavement base layer. Quality control (QC) results for the sensors are indicated by color coding in the profile view. According to the QC color coding, one LVDT is good; one is combined good and maybe; one is combined good, maybe, and not good; and one is not good. The two pressure cell sensors are good, three strain gauge sensors are not good, two strain gauge sensors are good, and one strain gauge sensor is combined maybe and not good.

This illustration shows the instrumentation layout in plan and profile views as well as the pavement layer structure in profile view for test section 390110 Ohio Specific Pavement Studies-1 test J10G, which had 12 test runs. A total of 15 sensors are indicated. The plan view in the top portion of the figure shows 12 sensors in a 22-ft horizontal row on the pavement wheelpath a short distance from the pavement edge. From left to right, the sensors are: two single-layer deflectometers, six alternating transverse and longitudinal strain gauges, two pressure cells, and two additional single-layer deflectometers. The single-layer deflectometers are the peaks of four linear variable differential transformers (LVDTs). The profile view in the bottom portion of the figure shows the four LVDTs extending downward through the pavement and pavement base layer, the six strain gauges embedded in the pavement, and five additional sensors that are not in the plan view. The five additional sensors include two pressure cells embedded just below the pavement base layer and three strain gauges in the pavement base layer. Quality control (QC) results for the sensors are indicated by color coding in the profile view. According to the QC color coding, two LVDTs are combined maybe and good and two are good. The two pressure cell sensors are good, five strain gauge sensors are not good, one strain gauge sensor is good, one strain gauge sensor is combined maybe and not good, and two strain gauge sensors are maybe
