旧水泥路面沥青加铺层技术的应用研究

针对旧水泥路面特点，提出采用柔性路面结构进行旧水泥路面改造，并提出了密实式沥青碎石基层结构的设计方法，沥青面层采用Superpave技术，理论分析及试验检测结果表明，路面结构强度很好，路面平整度、构造深度均满足高速公路的技术要求，具有很好的性能。

Application research of old cement pavement asphalt overlay technology

Aiming at the characteristics of the old cement pavement, the author provides method of getting old cement pavement transformation based on adopting flexible pavement structure, and provides design methods of the dense asphalt macadam subgrade structure, and the as-phalt adopting Superpave technology, theory analysis and test results show that the pavement structure has good strength, its smoothness and structure depth all satisfies technology requirement of the expressway, and has good performance.
