| 摘 要： | 试验研究了水泥稳定碎石试件,在室内静荷载作用下,浸水时间10～360d范围内的抗压强度、间接抗拉强度变化情况.同时,对比了冻融循环（-8～8℃）前后的试件抗压强度.试验数据表明：水泥稳定碎石试件的抗压强度和间接抗拉强度都保持前期较快、后期平缓的增长趋势,3次冻融循环后的抗压强度未出现明显的降低;因此,在长期浸水及冻融循...

| 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 ... |
