摘要
鉴于安徽省沿江高速公路沥青路面面层的结构特点,采用马歇尔和旋转压实联合控制的设计方法,通过对大粒径沥青混合料(AC-25C型)的前期试验研究,结果表明大型马歇尔成型的试件密实程度高、各种体积参数随沥青含量的变化表现出良好的参数特性,对指导施工具有重要的现实意义。
Because of the structure characteristic of bitumen pavement surtace of Anhui expressway along Yangtse River, it has guidance for construction to prove the high dense degree of big Marshall molding with good parameter characteristic of every volume unit with changing of bitumen content, using the design of Marshall and circumvolving pressure control and by the pre-test of big diameter grainule bitumen mixture.
