G320国道沥青路面养护策略研究

Study on maintenance strategy of national highway G320 asphalt pavement

为提高G320国道养护策略科学性,从原始路况分析到深度的检测,按照针对性养护设计的理念,重点对公里内采取的处治路段长度测算分析,结合养护目标,完成了专项养护设计。结果表明,针对性养护策略实施后,路段路况指标满足养护目标要求,为其他国道沥青路面养护策略的研究提供了有意义的借鉴。

In order to improve the scientific nature of the G320 national road maintenance strategy,from the original road condition analysis to the in-depth detection,according to the concept of targeted maintenance design,the length of the treated road section within a kilometer is mainly calculated and analyzed,and combined with the maintenance objectives,the special maintenance design is completed.The results show that after the implementation of targeted maintenance strategies,the road condition indexes of the sections meet the requirements of maintenance objectives,which provides a meaningful reference for the research of other national highway asphalt pavement maintenance strategies.
