Abstract: Long-term pavement performance in wet climates is directly related to the amount, extent, and duration of internal moisture. Retention of moisture in base/subbase layers can lead to damage and premature failure of the ...

Abstract: An accelerated testing system (ATS) has been designed with which simulated truck traffic can be applied to a pavement test section. Materials as well as environment and loading conditions can be controlled. A number of ...

Abstract: Resilient modulus tests were performed on three clayey subgrade soils with repeated-loading triaxial test equipment. For the laboratory-compacted samples, stress at 1% axial strain from the conventional unconfined compression ...

Abstract: A finite-element analysis was conducted of flexible pavement test sections subjected to a moving aircraft tire. The test sections failed primarily as a result of shear in the base course. Excavation of the test sections ...
