The objectives of this project was to conduct vehicle loading tests on the Ohio SHRP Test Pavement (US23) sections under hot weather conditions, collect and analyze pavement response and vehicle dynamic load data, and examine the validity of existing rutting models. To accomplish these objectives additional sensors (strain gauges and thermocouples) were installed at the SPS-8 sections of the Ohio-SHRP U.S. 23 Test Road. The FHWA Heavy Vehicle Test Truck was used to conduct load tests. The truck was loaded to 19.25 kips for all test series. Each series of test was repeated at least three times or until three different tire prints around the gauges were achieved. Four different sets of tires were used for these tests-two wide base tires and two sets of dual tires (M445 and G286wide base tires and G159 and M275 dual tires). Pavement temperatures and strain responses under truck loading test were collected during July 1996. The processed and cleaned load test data were delivered to ODOT and FHWA in CD-rom as text files. Series of laboratory tests were performed on the cores taken from the test pavements following laboratory test program prepared by FHWA. The laboratory test program included creep and relaxation tests, triangular pulse load tests with rise time varying from 4.5 to 36 milliseconds, with peak load varying from 360 to 2880 lb. For selected specimens, repeated load tests were performed. Processed and cleaned laboratory test data were also submitted to ODOT and FHWA for further analysis.
