半刚性路面早期病害的成因分析与对策

Analysis of the early failure in semi-rigid bituminous pavement and treatment methods

文章试图通过调查我国近年来修筑的一些半刚性高等级沥青混凝土路面出现的早期沉陷、开裂、坑洞、车辙、水损害等破坏现象 ,从设计规范、施工管理和材料控制等方面进行病害情况的主要原因分析 ,并提出了对症防治处理的一些措施。以期引起广大路面工作者的重视 ,同时对正在修建和将要修建的高速公路沥青混凝土路面施工质量控制 ,提供有益的指导与参考 ,减少和避免类似病害的再发生。

This paper has made an investigation of the failure in the semi rigid high grade asphalt pavements completed in recent years in China.The causes of the failure,such as early settlement, cracking, pot holes, rut and waterborne damage, are analyzed from standard specification, construction supervision and material control, and some corresponding treatment methods are presented.This study is helpful to the construction quality control of asphalt pavement which is being built or will be built in the country, reducing or avoiding similar early failure occuring again.
