分析了细集料棱角性常用评价方法的缺点,提出了一种新方法-CAR(Compacted Aggregate Resistance)法。该方法为单轴贯入试验,用贯入荷载表征细集料棱角性,试验结果表明,该方法能较好地评价细集料的形状和棱角性,CAR值与沥青混合料高温性能有较好的相关性。
The shortcomings of commonly used evaluation methods of fine aggregate angularity were analyzed and a new method called -CAR (Compacted Aggregate Resistance) method was proposed. The test results show that this method can evaluate the shape and angularity of fine aggregate well, and the CAR value is better than the high temperature performance of asphalt mixture Good relevance.
