Low-Temperature Cracking: Field Validation of the Thermal Stress Restrained Specimen Test
The purpose of the field validation program was to evaluate the thermal stress restrained specimen test (TSRST) as the accelerated performance test to predict low-temperature cracking of asphalt concrete mixtures. Construction histories, cracking observations, and temperature data were collected for five test roads. In addition, a validation program was conducted at the U.S. Army Cold Regions Research and Engineering Laboratory (USACRREL). The laboratory test program consisted of performing the TSRST on specimens fabricated in the laboratory with original materials from the test roads and asphalt concrete pavement specimens cut from the actual test sections. In addition, the field pavements were monitored for crack history and, where possible, crack initiation. TSRST fracture temperature correlated with field cracking temperature and crack frequency. TSRST results can be used to predict field low-temperature cracking of asphalt-aggregate mixtures. Preliminary models to predict cracking frequency and temperature for the test roads were developed.
