沥青路面冷再生基层路用性能试验研究

以立志路改造工程为依托,对以水泥粉煤灰作为添加剂稳定石灰土加沥青表处的冷再生基层进行强度特性、干缩特性、温缩特性、疲劳特性、水稳定性、冰冻稳定性、劈裂强度等路用性能的分析,并结合试验路后期技术指标观测,论证石灰土加沥青表处结构冷再生作为农村低等级公路沥青路面基层的技术可行性和适用性,有很大的现实意义。

Experimental Research on Pavement Performance of Cold Regenerative Base under Asphalt Pavement

According to the reconstruction project of Lizhi Highway,the pavement performance of cold regenerative base using cement fly ash as additive to stabilize surface treatment which mixes lime soil with asphalt are analyzed from the aspects of strength properties,dry shrinkage performance,temperature shrinkage performance,fatigue performance,water stability,freezing stability and splitting strength.The technical feasibility and applicability is proved combining with observations on later technical indexes of te...
