摘　　要：现有微表处技术指南中评价微表处路用性能的试验方法与实际情况差异较大,影响了微表处技术的应用与发展。以小型加速加载试验设备(MMLS3)为基础试验平台,通过室内加速加载试验研究岩沥青种类、掺量对微表处混合料高温稳定性的影响。研究结果表明,掺加3种不同种类的岩沥青微表处混合料的高温稳定性都有不同程度的提高。研究结果同时表明了小型加速加载试验设备(MMLS3)可真实模拟轮胎与路面间的相互作用,快速和定量评价路面的高温稳定性。A distinct deviation appears between the results of the test methods of micro-surfacing technical guideline and actual pavement performance,which influences the mico-surfacing application. Based on MMLS3, the indoor acceler-ated test on micro-surfacing was carried out to study the impact of type and content of asphalt on high temperature stabili-ty. Test results show that the high temperature stability of rock asphalt can he im proved differently by increacing 3 kinds of micro-surfacing rcok asphalt. Test results also show that the interaction between tires and pavement can be simulated by MMLS3, as a result, the high temperature stability can be evaluated quantitatively and efficiently.
