摘要
多指标设计体系是一种与既有沥青路面设计方法区别较大的新设计体系,基于多指标沥青路面设计方法,结合辽宁地区的筑路材料来源、交通条件、路基条件和经济发展条件以及已有试验工程的使用情况,对辽宁省高速公路沥青路面典型结构进行分析和验算,验证了多指标设计体系在辽宁省的适用性,避免了因设计体系转变较大带来的工程建设问题,为多指标沥青路面设计体系在辽宁省更好地应用提供技术支持。
The multi index design system is a new one which is quite different from the design method for the existing asphalt pavement.Based on the design method for the multi index asphalt pavement,combined with the source of road building materials,traffic conditions,subgrade conditions and economic development conditions in Liaoning area as well as the service condition of the existing test projects,the analysis and checking calculation on the typical structure of expressway asphalt pavement in Liaoning are carried out,so as to verify the applicability of the multi index design system in Liaoning province,avoid the engineering construction problems caused by the large transformation of the design system,and provide technical support for the better application of the multi index asphalt pavement design system in Liaoning province.
