摘要

本研究的目的是探索使用单调加载试验(“单调试验”)作为筛选工具来评估弗吉尼亚州密级沥青表面混合物的车辙潜力。为此，从文献中确定的三个单调试验——高温间接拉伸(IDT-HT)试验、快速车辙(RR)试验和马歇尔稳定性和流动(MS)试验——使用16种具有“A”和“D”标志的植物生产的沥青混合物进行了评估。工作范围还包括对提取和回收的粘合剂进行多次应力蠕变和恢复测试。利用几个性能指标对单调试验和沥青路面分析仪(APA)试验进行了相对评价。这些结果还用于为正在考虑的测试制定性能阈值标准。结果表明，IDT-HT和RR试验可用于筛选符合弗吉尼亚州交通部(VDOT)混合料体积和级配要求的A和D混合料的车辙势。为这些混合物建立了IDT-HT和RR试验的初始性能标准。结果表明，IDT-HT试验是APA试验最合适的替代试验。

Evaluating the Rutting Potential of Asphalt Mixtures with Simple and Practical Tests

The objective of this study was to explore the use of monotonic loading tests (“monotonic tests”) as screening tools to assess the rutting potential of dense-graded asphalt surface mixtures in Virginia. To that end, three monotonic tests—the indirect tensile at high temperature (IDT-HT) test, the rapid rutting (RR) test, and the Marshall stability and flow (MS) test—identified from the literature, were evaluated using 16 plant-produced asphalt mixtures with “A” and “D” designations. The scope of the work also included performing the multiple stress creep and recovery test on the extracted and recovered binders. The results were applied to assess the monotonic tests and the asphalt pavement analyzer (APA) test relative to each other using several performance metrics. The results were also employed to develop performance threshold criteria for the tests being considered. The results showed that the IDT-HT and RR tests can be used to screen the rutting potential of asphalt mixtures meeting the Virginia Department of Transportation (VDOT) mixture volumetric and gradation requirements for A and D mixtures. The initial performance criteria for the IDT-HT and RR tests were established for these mixtures. Based on the results, the IDT-HT test was found to be the most suitable alternative test to the APA test.
