摘要
为贯彻"预防为主,防治结合"方针,延缓沥青路面病害的发展,需要采用预养护性措施,延长路面使用寿命、提升公路服务水平。本文简要综述沥青路面的病害类型和原因,并介绍了常见预防性养护技术措施的类型和选择,并以厦门市某道路为例,阐述采用橡胶沥青灌缝对沥青路面裂缝进行灌缝修补的施工技术及质量控制要点。研究表明:采用橡胶沥青灌缝处理,可减少路面坑槽或破损,节约建筑材料,具有显著的经济效益;实施处理1年内继续发展为网裂、龟裂、沉陷等病害的≦5%,两年内≦15%,证明了灌缝预防性养护具有良好的技术效果。
In order to implement the policy of"prevention first and control combined"and delay the development of asphalt pavement diseases,it is necessary to adopt pre-maintenance measures to prolong pavement service life and improve highway service level.This paper briefly summarizes the types and causes of asphalt pavement diseases,introduces the types and selection of common preventive maintenance technical measures,and takes a road in Xiamen as an example.This paper expounds the construction technology and quality control points of filling and repairing the cracks of asphalt pavement with rubber asphalt,and summarizes the implementation effect.The research shows that the treatment of intersecting asphalt pouring joint can reduce the pit or damage of pavement,save building materials and have remarkable economic benefits;Within one year after the implementation of treatment,no more than 5%of diseases will continue to develop into net crack,crack and settlement,and no more than 15%within two years,which proves that the preventive maintenance of grouting joint has good technical effect.
