高速公路桥面铺装早期病害产生原因及养护措施

Reasons for Early Stage Disease of Deck Parement of Freeway and Measures for Maintenance

随着我国高等级公路通车里程的不断增长,为保证高速公路行车的安全、快捷。必须及时对高速公路桥面铺装早期病害进行处治。本文通过对高速公路桥面铺装产生的裂缝、拥包、松散、坑槽和纵向通缝等病害现象的表现形态进行调查分析,从设计因素、自然因素、材料性能、行车荷载、和施工环节等几方面就以上病害产生的原因进行了分析。并结合养护工程实践,简要介绍了对高速公路桥面铺装针对不同的病害种类和损坏程度处治所采取的几种养护措施。

With continuous growth of mileages that high - type highway in our country are open to traffic, it＇s necessary to treat in time the early stage disease of deck pavement so as to ensure driving safetyand speed. The paper first of all analyzes the phenomena of crack, swelling,ravel, chuck hole and longitudinal through crack etc. , then analyzes also the reasons for above -mentioned disease from design factors, natural factors, material performance, driving load and construction links etc. , moreover introduces briefly several measures for maintenance, taken aiming at categories of disease and deflection degree.
