高模量沥青混合料高温评价指标及试验结果分析

High-temperature Evaluating Indicator & Analysis of Rutting Test for High Modulus Asphalt Mixture

通过对AC-20C和SUP-20型两种沥青混合料掺加不同掺量的改性剂(PR和RA)进行车辙试验,应用灰色关联分析及统计学检验方法可知,马歇尔稳定度和马歇尔模数是影响车辙试验结果的主要因素,且当级配由AC-20C转化为SUP-20时,其对车辙试验结果影响较小。

By way of rutting test for asphalt mixture types of AC-20C and SUP-20 mixing two different content of modifying agent （PR and RA）, Marshall stability and Marshall modulus are the main factors affecting the rutting test by utilized gray relational analysis and statistical testing methods. When the gradation changes from AC-20C into SUP-20, there is less affection on the results of the rutting test.
