摘　　要：通过试验段不同沥青芯样CPN试验结果进行对比发现:高模量、矿物纤维改性沥青具有较好抗车辙性,能够明显提高路面高温稳定性。通过数字图像研究发现两者抗车辙能力优于SBS改性沥青混合料,适合于重载、长陡坡路段使用。CPN Experimental Results of different asphalt mixture core samples of test section is compared and found high modulus,mineral fiber modified asphalt mixture has better resistance to rutting and can improve high temperature stability of pavement.Study by digital image technology found the anti-rutting performance of the two mentioned before is better than SBS modified asphalt mixture.The two is more suitable for heavy,long steep road.
