摘要：	The primary objective of the study was for the Center for Electromechanics, The University of Texas at Austin, to evaluate the Texas Mobile Load Simulator (TxMLS) equipment to recommend the most appropriate rehabilitation options. Within this framework, the research proposed in Project 0-5372 aimed at making the best possible use of the traffic loads that were to be applied as part of the evaluation. A series of secondary objectives included: (1) quantifying the response and performance of a relatively light pavement structure with increased traffic load applications; (2) comparing the performance of the same pavement structure under different axle loads; (3) developing a methodology to estimate the reduction in expected pavement performance as a result of increased axle loads. The contract under which the repairs to the TxMLS and the necessary traffic load tests were to be conducted was discontinued in August 2005. At that time, approximately 40,000 axle load repetitions had been applied to one of the test pads, which did not provide enough data to address the research objectives described above. Therefore, this research report addresses only part of the third objective: the development of a methodology for the estimation of pavement damage under different axle loads and configurations. In addition, results of the asphalt mixture fatigue testing used for the construction of the HB2060 test pads are presented. / NOTE:Technical rept. (Jan. 2005-Aug. 2005).
