高温多雨区半刚性基层长寿命沥青路面设计

Design of Long-life Asphalt Pavement of Semi-rigid Base in High Temperature Rainy Area

我国已建成较为完备的公路体系和城市路网。新的道路建设需要在保证质量的基础上逐步实现道路的绿色可持续发展。现依托重庆地区某沿江城市道路改建工程,在旧路病害调研的基础上,根据当地工程建设经验,借鉴国外长寿命路面设计理论,参考公路和城镇道路相关设计规范,采用路面结构批处理分析技术和有限单元数值模拟方法,提出适宜于高温多雨区的城市道路长寿命沥青路面结构。其研究成果对于相同气候地区的城市道路建设具有一定的参考价值。

The perfected highway system and urban road network have been established in China.The construction of new roads is required to realize the green and sustainable development step by step on the basis of ensured quality.Relying on a riverside urban road reconstruction project in Chongqing City,on the basis of studying the diseases of old roads,based on the local engineering construction experience,referring the design theory of foreign long-life pavements,according to the related design specifications of highway and town roads,and using the pavement structure batch treatment analysis technology and finite element numerical simulation method,the long-life asphalt pavement structure of urban road suitable for the high-temperature rainy areas is proposed.The study result has some referring values for the construction of urban roads in the similar climate areas.
