Book Description
As part of its support for the Strategic Highway Research Program (SHRP), the Ohio Department of Transportation, in conjunction with the Federal Highway Administration constructed a comprehensive test road encompassing four of nine experiments in the Specific Pavement Studies (SPS) of SHRP. The 3.4 mile long project is located on US 23 in Delaware County. The Ohio/SHRP test road is a four lane divided highway constructed in the 170 foot wide median of the existing facility. The new southbound lanes were constructed of asphalt concrete (AC) and contain the SPS-1 and SPS-9 experiment. The new northbound lanes were constructed using Portland cement concrete (PCC) and contain the SPS-2 experiment. Once ODOT decided to participate in the SHRP, staff engineers viewed this as an opportunity to obtain pavement response data for validating and calibrating pavement analysis models. After review of the experimental design of the SHRP sections, thirty three of the forty original sections were chosen for environmental and dynamic load response instrumentation using a total of 1296 gages for measuring strain, deflection, pressure, moisture, temperature, and frost depth. Research was needed to calibrate, install, and to measure pavement response during controlled loading, moisture and temperature in the pavement structure, and climatic conditions above the pavement. Due to the large number of gages being installed, the effort was divided among six universities. The University of Cincinnati was one of two universities responsible for the calibration and installation of dynamic response instrumentation.

Book Description
Objective: Over the years, the Ohio Department of Transportation has constructed several pavements with a range of designs and materials to study and improve overall statewide performance. These pavements require constant monitoring to determine how they perform over time and what mechanisms are at work to cause distress. One major effort was the DEL-23 Test Road where 40 AC and PCC test sections in the SPS-1, SPS-2, SPS-8 and SPS-9 experiments were constructed for SHRP. While many sections have been replaced, many other sections remain in service. These remaining sections and seven PCC replacement sections need to be evaluated periodically. Other existing test roads around the state also need ongoing evaluation to assess performance, including in particular the perpetual AC pavement and long-life PCC pavement in Wayne County (WAY-30).

Book Description
A Specific Pavement Studies (SPS) program, formulated under the Strategic Highway Research Program (SHRP), consists of nine experiments, four of which will be included in this DEL-23 project. Since the basic instrumentation plan proposed by SHRP was limited, Ohio Department of Transportation opted to develop a more comprehensive plan for DEL-23. The Ohio Test Road consists of SPS-1, SPS-2, SPS-8, and SPS-9 experiments, all constructed for this project where the climate, soil, and topography are uniform throughout. In this comprehensive instrumentation plan, thirty-three sections are to be instrumented. LTPP guidelines require four instrumented sections in each of the SPS-1 and SPS-2 experiments for the study of seasonal factors and dynamic response. DEL-23 includes an additional nine instrumented sections for the SPS-1 experiment, twelve sections for the SPS-2 experiment, and two sections each in the SPS-8 and SPS-9 experiments to study structural response parameters. A total of eighteen sections will be instrumented for the study of seasonal factors, ten more sections than required by SHRF. This report provides a detailed description of types of sensors, installation and methodology, calibration procedures and wiring schematics for instrumentation of pavements for the Ohio SHRP SPS Test Road to measure environmental factors and structural response. Environmental or climatic paramaters include temperature, base and subbase moisture, and frost depth. Structural response parameters entail strain, deflection, pressure and joint opening.

Book Description
The Ohio Department of Transportation constructed an experimental pavement for the Strategic Highway Research Program (SHRP) on U.S. 23 north of Columbus, which included 40 asphalt and concrete test sections in the SPS-1, 2, 8 and 9 experiments. These sections controlled various combinations of structural parameters known to affect performance. To enhance the value of this pavement, sensors were installed in 18 test sections to continuously monitor temperature, moisture and frost within the pavement structure, and 33 test sections were instrumented to monitor strain, deflection and pressure generated by environmental cycling and dynamic loading. Also, two weigh-in motion systems and a weather station were installed to continuously gather the necessary traffic and climatic information required to properly interpret the performance data. Six universities, including Ohio University, which coordinated this effort, were responsible for installing and monitoring the instrumentation. Nondestructive testing conducted with the FWD and Dynaflect, and five series of controlled vehicle tests were performed between 1995 and 1998 to assess the response of these test sections to dynamic loading. This report documents how the instrumentation was installed and monitored, provides details of controlled vehicle tests, and summarizes results of the nondestructive testing.
