把现行规范抗滑表层 AK- 13A混合料的级配组成改进为断级配骨架型密实混合料 ,并提出相应的设计标准。改进后的抗滑表层铺筑工艺与 SMA路面相似。福建省同三线高速公路大量工程实践表明 ,改进型 AK-13A抗滑表层不仅具有优良的抗车辙能力与抗滑性能 ,而且路面基本不渗水 ,为解决我国高速公路沥青混凝土路面常见的早期损坏问题提供了可靠途径
The current standard anti-slip surface AK-13A mixture of graded composition improved broken grade with skeleton-type dense mixture, and put forward the corresponding design standards. Improved anti-skid surface paving process and SMA pavement similar. A large number of engineering practice on the same three-lane expressway in Fujian Province shows that the improved AK-13A anti-slip surface not only has excellent anti-rutting ability and anti-skid performance, but also is not permeable to the road surface. In order to solve the common early damage problems of asphalt pavement in our country, Provide a reliable way
