摘要
沥青路面现场压实度对路面使用性能影响显著,车辙、水损害、疲劳开裂等沥青路面早期损害均与路面现场压实度过大或过小有关。路面现场压实度计算,目前可采用马歇尔密度作为标准密度或采用最大理论相对密度作为标准密度。对采用最大理论相对密度进行现场压实度控制的重要性进行探讨。
Asphalt pavement site compaction has obvious influence to pavement performance,premature damage to asphalt pavement,such as track,water damage,fatigue fracture,etc.,are closely related to excessive or inadequate pavement compaction.For pavement compaction computing,currently we may adopt Marshall density as standard density or adopt theoretical maximum relative density as standard density.This paper adopts theoretical maximum relative density to explore the importance on-site pavement compaction control.
