| 摘要： | The focus of this project is to develop an integrated hot-mix asphalt (HMA) mixture design method which balances both rutting and cracking requirements. The Hamburg Wheel Tracking Test (HWTT) and Overlay Tester (OT) devices were used to evaluate the rutting and cracking resistance of HMA mixtures, respectively. Eleven mixtures commonly used in Texas were designed following the current Texas Department of Transportation (TxDOT) mixture design process and then evaluated under the HWTT and the OT. It was found that the Dense-Graded and Superpave mixtures designed following current TxDOT mixture design procedures were rut resistant, but generally not crack resistant. However, all three Stone-Matrix Asphalt (SMA) mixtures were both rut and crack resistant. These observations are consistent with the past experience and field performance. / NOTE:Technical rept.
