城市道路沥青路面水损害防治技术研究

A Study of Water Damage Prevention Technology of Urban Asphalt Pavement

城市道路沥青路面的水损害是目前路面最常见的破坏现象之一。针对每一种常见的损害形式,研究分析了产生的原因或机制,在此基础上,总结出完善排水系统、防治路面裂缝、合理控制压实度、提高沥青黏附性、防治沥青混合料离析和养护、管理等方面的技术措施,从而达到延长沥青路面使用寿命的目的。

It is one of the most common phenomena of water damage on urban asphalt pavement.Aiming at every regular damage type,the relevant reason or mechanism is analyzed,and on the basis of these researches several helpful technology measures are summarized to arrive at prolonging the service time of asphalt pavement.These measures are about perfecting drainage system,preventing pavement cracks,controlling compaction degree reasonably,improving asphalt adherence performance,preventing asphalt mixture segregation,and maintenance & management,etc.
