基于长寿命路面结构的市政道路沥青路面加铺研究

Research on Asphalt Pavement Construction of Municipal Road Basing on Long- Life Pavement Structure

在借鉴国内外长寿命路面的研究与发展经验基础上,针对北京气候、交通情况、原材料技术性能等,通过对比分析,确定了市政道路加铺路面表面层、下面层、应力吸收层的材料;同时经过应力、应变分析及验算确定了每层材料厚度。

Basing on the research and development experience on long -life pavement at home and abroad, aiming at some aspects like Beijing＇s climatic features, traffic conditions, technical performance of raw materials and so on, andbasing on the contrastive analysis, the materials for surface layer, lower layer and stress absorbing layer of pavement of municipal road are determined, and meanwhile the thickness of materials at each layer are determined by stress, strain analysis and check calculation.
