近年来,我们找出了一种比较适合我区特点的公路养护方法:采用废机油拌砂、石混合料,对低等级公路进行封面和修补坑槽。采用此方法修复路面,施工简便易行、造价低、维修速度快、效果好,而且路面的强度、稳定性和抗冻性都能达到使用要求。通过冻胀观测和强度、稳定性等技术分析,是比较适合我区的一种公路养护方法。
In recent years, we have identified a method of road maintenance that is more suitable for the characteristics of our region: the use of waste oil mixing sand, stone mixture, low-grade road cover and repair pit. Using this method to repair the pavement, the construction is simple and easy, the construction cost is low, the maintenance speed is fast, the effect is good, and the strength, stability and frost resistance of the pavement can meet the requirements. Through the frost heave observation and strength, stability and other technical analysis, is more suitable for our district a road maintenance methods.
