不同养生温度下半刚性基层材料路用性能试验研究

摘要

通过室内试验,研究了在10℃和20℃两种养生温度下,对3种常用的半刚性基层材料进行无侧限抗压强度试验、劈裂强度试验以及抗压回弹模量试验.试验结果表明:与养生温度为20℃时相比,在养生温度为10℃时,半刚性基层材料的路用性能均有所降低,但是降幅不同.养生温度对半刚性基层材料路用性能的影响大小为:劈裂强度＞抗压回弹模量＞无侧限抗压强度.%Through laboratory testing,Studied at 10 ℃ and 20 ℃ of two kinds of curing temperature,three kinds of commonly used semi-rigid materials unconfined compressive strength test,splitting strength test and the compression modulus test.The results showed that:when the curing temperature is 20 ℃,in the curing temperature is 10 ℃,the semi-rigid materials,pavement performance has decreased,but the decline are different.Curing temperature on the road with semi-rigid material properties of size,splitting strength ＞ compression modulus ＞ unconfined compressive strength.
