前言沥青表处路面的中修是一项定期性的工作,目的在于恢复路面原有的技术状态。中修周期的长短决定于现有油路的基层强度、施工和养护质量、交通量以及气候水文等诸多因素,因此,全省采用统一的中修年限是不合理的,解决的办法是寻找确定中修周期的方法或定出一个油路中修的技术界限。自一九八一年到一九八二年我省共有八个总段150多人参加了此项工作,对我省现有油路作了比较全面的抽样调查,搜集数据十多万个,进行了综合分析,从而为确定我省沥青表处路面经济合理的中修周期作了些探索,亦可供我国南方各省(区)参考。
Preface The repair of the asphalt pavement at the surface is a regular exercise aimed at restoring the original technical condition of the pavement. The length of the repair cycle depends on the strength of the grassroots, the quality of construction and maintenance, traffic volume and climate and hydrology of the existing oil lines. Therefore, it is unreasonable for the province to adopt a unified repair term, and the solution is to find a definite The method of repair in the cycle or set out a repair of the technical boundaries of the oil. From 1981 to 1982, a total of more than 150 people from eight sections in our province took part in this work. They made a comparatively comprehensive sample survey of the existing oil routes in our province and collected over 100,000 data, A comprehensive analysis was carried out to make some exploration for determining the economical and reasonable repair period of asphalt pavement in our province and also for the reference of all provinces (districts) in our country.
