水泥稳定碎石基层长期浸水及冻融试验研究
Long-term water immersion and freeze-thaw cycles experiment of cement-stabilized macadam bases
摘要
Abstract
At present,cement-stabilized macadam is a typical base course material widely used in highway and street engineering in China,whose strength change will directly affect the service life of the road under long-term water immersion and freeze-thaw cycles.The changing compressive strength and tensile strength of the cement-stabilized macadam base samples were tested.Their conditions were as follows： laboratory test static load with immersion time 10~360 d.The comparison between the compressive strength of the samples before and after the freeze-thaw cycles（-8~8℃） were researched and discussed.The result of the experiment shows that the compressive strength and tensile strength both keep up a fast growth trend at earlier stage and stay smooth trend at late stage while the compressive strength does not decrease apparently after three freeze-thaw cycles.Thus,the cement-stabilized macadam base can hold over its performance in the condition of long-term water immersion and freeze-thaw cycles.关键词
