Available in PDF, EPUB and Kindle. Book excerpt: In 1995 and 1996 the Ohio Department of Transportation, in cooperation with the Federal Highway Administration and the Strategic Highway Research Program (SHRP), built a nearly 3.5 mile long Experimental Test Road in the median of the existing U.S. 23 in Delaware County, Ohio. The Test Road is a four-lane, divided and limited access highway. Its southbound two lanes were built using Asphalt Concrete, while the northbound two lanes were built of Portland Cement Concrete (PCC). This report deals with the horizontal movements of the contraction joints in the northbound driving lanes of the PCC pavement. Ten pavement sections were chosen to measure joint movements in both the Winter and Summer seasons. Five consecutive joints were selected in each section. Brass plugs were installed at each joint to allow manual measurement of the joint movements. Measurements were made during the morning and afternoon, both in the Winter and the Summer of 1998. The results were used to investigate the effect of the following factors on the design and performance of joints in PCC pavements with 15-ft joint spacings: strength of concrete, thickness of the PCC pavement, type of base, and range of temperatures. The results provide further data to researchers and designers for the selection of appropriate sealant materials.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental instruments to measure temperature, soil moisture and frost depth were installed at five test sections of the SHRP pavement project on U.S. 23 north of Delaware, Ohio. At three of these locations tensiometers, which a designed to measure negative pore pressures, were added to the instrumentation package. The pore pressures as recorded by the tensiometers have increased from initially negative to positive values at each location and throughout the profile in the first year after installation of the instrument package was completed. At the same time, data collected from the moisture probes were showing a corresponding increase in soil moisture content. Samples of an aggregate base and clayey subgrade material were collected at several locations on the DEL 23 project by ODOT. They were delivered to the OSU soil mechanics laboratory for classification and permeability determination. The aggregate base conformed to ODOT material specification Item 304. Measured permeability coefficients ranged between 2x10 [to the minus 2] and 2.9x10 [to the minus 2] cm /sec. The clayey material was classified as a low plasticity clay (AASHTO Classification A-6 to A-7-6) with permeability coefficients ranging between 1x10 [to the minus 6] and 4x10 [to the minus 8] cm/sec.
