高劲度模量沥青混合料在京台高速车辙维修段的应用

Application of high stiffness modulus asphalt mixture in JingTai expressway

按照法国LCPC沥青混合料设计方法对高模量沥青混合料进行设计,研究发现设计的高劲度模量混合料具有较高的水稳定性、高温抗车辙性以及疲劳性能,并在京台高速夏津段抗车辙维修工程中成功地进行了推广应用,为提高养护施工的延续性,减少施工接缝,延长道路使用寿命,达到养护资金使用效率的最大化起到了决定性作用。

In this paper,according to the French LCPC asphalt mixture design method,the high modulus asphalt mixture is designed. It is found that the designed highstiffness modulus mixture has high water stability,high temperature resistance to rutting and fatigue performance. It has been successfully applied in the anti-rut maintenance project of Xiajin section of Beijing-Taiwan Expressway. It has played a decisive role in improving the continuity of maintenance construction,reducing construction joints,extending the service life of roads and maximizing the use of maintenance funds.
