本文为国家自然科学基金资助的课题。它研究了一种新型路面的复合材料——特种沥青混合料,它是在密或开级配的沥青混合料中,用拌和或灌浆的制备工艺,掺加特种水泥砂浆作为第二结合料,从而提高沥青混合料的高温稳定性、低温抗裂性、粘附性、抗滑性及耐久性等,特别是抵抗沥青路面的永久变形和车辙更有较好的效果。通过室内大量的试验结果与普通沥青混合料相比,证明各种路用性能均有明显的提高。该种材料适用于修筑城市道路的交叉口、停车站、停车场、高速公路及机场跑道沥青路面的面层,它的路用性能既不同于柔性路面,又不同于刚性路面,是一种新型半刚性路面的复合材料。这种特种沥青混合料我所已经应用到某省繁妻交通高等级沥青路面中去,经二年路况观察,使用性能良好。 This article is funded by the National Natural Science Foundation of China. It studied a new type of pavement composite material - special asphalt mixture, which is in dense or open graded asphalt mixture, with mixing or grouting preparation process, adding special cement mortar as the second binder, Thereby improving the high temperature stability of asphalt mixture, low temperature crack resistance, adhesion, skid resistance and durability, especially against asphalt pavement permanent deformation and rutting more good results. Through a large number of indoor test results compared with ordinary asphalt mixture, to prove a variety of road performance have significantly improved. The material is suitable for the construction of the intersection of urban roads, parking, parking, highway and airport runway asphalt pavement, its road performance is different from the flexible road, but also different from the rigid road, is a new type Semi-rigid pavement composite material. This kind of special asphalt mixture has been applied to the high-grade asphalt pavement of the wife-in-law in some province. After two years of traffic observation, the performance is good.
