摘　　要：为解决道路改扩建工程中交通组织和工期紧张问题,使用密级配沥青稳定碎石混合料(ATB-30)的基层代替原先设计的碎石垫层和水稳基层。此次尝试效果显著,加快了施工速度,降低了道路施工对周边居民和过往行人、车辆的影响,只用了5 d时间便完成了原计划1个月的工作任务。在经济条件允许的情况下,此举亦是一种解决工期和交通组织问题的方式。To solve the problems of traffic organization and tight construction period in road reconstruction and expansion projects,the base course of dense asphalt stabilized macadam mixture(ATB-30)is used to replace the originally designed macadam cushion and water stabilized base course.This attempt achieves remarkable results,accelerates the construction speed,reduces the impact of road construction on the surrounding residents,pedestrians and vehicles passing by.It took only 5 days to complete the original one month task.If economic conditions permit,this is also a way to solve the problems of construction period and traffic organization.
