沥青混合料种类与路面寿命的关系

Relationship between Mixture Species and Pavement Life

通过对各种沥青混合料路面的调研分析发现,病害的发生往往不是孤立的,而是几种病害同时发生,损坏的原因也是内外因素兼有,比较复杂,其既与公路建设的管理有关,也与路面结构设计、施工质量控制以及原材料的选用有关,同时也与运营期的合理养护措施、交通荷载及自然环境作用有关。

It is deduced that highway diseases aren＇t isolated and composed of sereval kinds according to various asphalt mixture pavement investigations. Reasons of highway diseases are complex, including exterior and interior factors, which are associated with highway construction and management, pavement structure design, construction quality control, raw material selection, and also reasonable maintenance countermeasures during operation period, traffic volume and environmental function.
