重庆渝邻高速公路排水性沥青混凝土路面修筑与性能

介绍了重庆渝邻高速公路排水性沥青混凝土路面的材料、结构、施工、成本及使用性能。试验路使用了3种改性沥青，设计实施了4种试验路段，具有不同的设计空隙率。通过试验路的修筑，检验并验证了排水性沥青混合料的材料设计方法，总结了排水性沥青混凝土路面的施工工艺与质量控制技术，实际考察了排水性沥青混凝土路面的使用性能。试验效果表明，排水性沥青混凝土路面雨天表面不积水，车辆行驶时不会产生溅水和水雾现象，车辆行驶视线好，路面表面粗糙，构造深度大，抗滑性能高，大大提高雨天行车的安全性，还具有降低路面噪声的功能。排水性沥青混凝土路面是一种具有优良路用性能的高速公路表层结构，非常适合在我国南方多雨地区使用。

Construction and Performance of Porous Asphalt Concrete Pavements of Yu-Ling Expressway in Chongqing City

It is presented in this paper that the pavement structure, the material design, construction techniques, costs and performances of porous asphalt concrete pavements in the test road built on Yu-Lin Expressway in Chongqi City. Three kinds of modified asphalt and different percentages of voids are used in the four test sections. By means of the test road practice, the mixture design method is verified, the construction techniqus and quality control measures are summarized. Test data and project practice both show that porous asphalt pavement have many good performances such as surface drainage, high skid resistance, nospraying , no splashing and good visibility in rainy day; besides,the porous asphalt pavement is a kind of low noise pavements. In brief,the porous asphalt pavement has many good surface functions and is suitable for the expressway pavements in the southern rainy area of China.
