摘要
为加强中下面层的抗车辙性能,减少路面结构车辙,文章依托某高速公路系统地对高模量沥青混合料进行了研究,提出了高模量沥青混合料的设计方法,并验证了其路用性能,最后明确了高模量沥青路面的施工工艺。试验结果表明:橡胶沥青混合料具有良好的高温稳定性、水稳定性和抗疲劳性,可广泛应用于高速公路路面工程施工。
In order to strengthen the anti-rutting performance of the middle and lower layers and reduce the rutting of the pavement structure,this paper systematically studies the high modulus asphalt mixture based on an expressway,puts forward the design method of the high modulus asphalt mixture,verifies its road performance,and finally clarifies the construction technology of the high modulus asphalt pavement.The test results show that rubber asphalt mixture has good high temperature stability,water stability and fatigue resistance,and can be widely used in expressway pavement construction.
