摘要:

针对添加专用外掺剂PR Module的高模量沥青混凝土(HMAC)的力学性能展开室内和现场测试研究.试验结果显示,外掺剂使得沥青混凝土材料的回弹模量值提高45%,动态模量提高了77%以上,而现场落锤式弯沉仪(FWD)的测试结果显示,高模量沥青混凝土路面的综合模量高于SBS改性沥青路面的综合模量,该外掺剂是改善路面结构整体承载能力的良好选择.

Abstract:

Indoor and field test studies were carried out on the mechanical properties of high-modulus asphalt concrete (HMAC) with special admixture PR Module. The test results show that the external admixture increases the rebound modulus value of asphalt concrete material by 45% and the dynamic modulus by more than 77%, while the test results of the on-site drop weight deflection meter (FWD) show that the comprehensive modulus of high-modulus asphalt concrete pavement is higher than that of SBS modified asphalt pavement, and the external admixture is a good choice to improve the overall bearing capacity of the pavement structure.
