摘要
水泥石灰综合稳定碎石土基层因其良好的经济效益,在陕北地区得到广泛应用。文中介绍了水泥石灰综合稳定碎石土的抗压强度、水稳定性、冻稳定性、回弹模量试验研究,结果表明,路面设计应考虑防冻层的要求,避免路面基层发生冻胀而产生其他路面病害。
Cement lime composite stabilized gravel soil foundation has been widely applied in north Shanxi areas for its good economic benefit. This paper introduces the test on compressive strength, moisture sensitivity, freezing stability, resilience modulus of cement lime composite stabilized gravel soil. The result indicates that the requirement of frost protection layer shall be considered in pavement design to prevent other pavement disasters due to frost heaving of subgrade.
