无机结合料稳定低液限粉土路用性能试验研究

为了研究水泥、石灰等无机结合料稳定低液限粉性土的路用性能,对石灰和水泥稳定粉性土的混合料配比进行了设计,通过无侧限抗压强度试验、劈裂强度试验和水稳定性试验,对其路用性能进行了评价。结果表明,8%的石灰稳定粉性土和5%水泥稳定土满足二级及二级以下公路基层要求,8%的石灰稳定粉性土水稳定较差,不适合用于水文地质条件较差路段。

Experimental Study on Pavement Performance of Low Liquid Limit Silt Stabilized by Inorganic Binder

In order to study the pavement performance of low liquid limit silt stabilized by cement,lime and other inorganic binders,the mix proportion design of cement and lime stabilized silt was designed.Through unconfined compressive strength test,splitting strength test and water stability test,the pavement performance of such slit was evaluated.The results showed that 8 % lime stabilized silt and 5 % cement-stabilized soil can satisfy the requirement of second-class road base and below.8 % lime stabilized silt has poor water stability,which is not suitable for the section under poor hydrogeological conditions.
