摘　　要：对添加专用外掺剂PR Module外掺剂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％，动态模量提高接近一倍，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。The mechanical property of high modulus asphalt concrete（HMAC） is evaluated, which is prepared through adding PR FLEX Module additive into asphalt mixture. The results illustrated that the resilient modulus of the high modulus asphalt mix is 45 percents higher than that of the conventional asphalt mix, the dynamic modulus of the HMAC is nearly twice of the conventional one. The Falling Weight Deflectometer（FWD） results show that the back-calculated modulus of HMAC pavement is higher than that of SBS modified asphalt pavement. The additive can improve the mechanical property of the asphalt pavement significantly.
