| 摘要： | This report examines the feasibility of using the thermal stress restrained specimen test to evaluate low temperature cracking in asphalt pavement mixes. Data were collected from laboratory and field evaluations. Various mixing, aging, and compaction methods were used to prepare test samples with materials obtained from two WYDOT highway projects. Field data were obtained from two recently built test sections to compare with laboratory test results. Pavement condition surveys quantified low temperature cracking of both test sections after one winter. Temperature data for these projects sites were also collected. Pavement condition and temperature data were compared to results from the thermal stress restrained specimen test. |
