养生温度对水泥稳定碎石基层抗裂性能的影响

Influence of Curing Temperature on Crack Resistance of Cement-Stabilized Macadam Base Course Material

在养生温度为25°C和10°C的情况下,分别对水泥稳定碎石基层材料进行无侧限抗压强度试验、干缩试验以及温缩试验.比较这2种养生温度下的试验结果发现:养生温度对水泥稳定碎石的强度及收缩性能均有影响;低温条件下养生、施工有利于改善水泥稳定碎石基层材料的抗裂性能.

A series of trials on cement-stabilized base course mateials, such as unconfined compressive strength,dry shrinkage and temperature shrinkage,were done under the condition of curing temperature 25 ℃ and 10℃. It is found by comparing trial results that curing temperature has influence on strength and shrinkage performance of cement-stabilized macadam. Curing and constructing for cement-stabilized macadam under the condition of lower temperature is benefit to improve its crack resistance.
