摘　　要：为评价SRX聚合物稳定碎石的力学强度,通过室内试验,对抗压强度、劈裂强度、CBR、回弹模量等指标进行测试,最后建立力学指标间的相互关系。结果显示,SRX聚合物属于柔性基层材料,其对级配碎石力学强度的提高有显著积极的作用;CBR与抗压强度呈线性关系,与劈裂强度、回弹模量之间均呈幂指数关系。相关结论可为路面结构设计和后续研究提供参考。In order to evaluate the mechanical strength of SRX polymer stabilized crushed stone,indoor tests were conducted to test indicators such as compressive strength,splitting strength,CBR,and rebound modulus.The interrelationships between mechanical indicators were established.The results show that SRX polymer functions as a flexible base material and significantly enhances the mechanical strength of graded crushed stone.CBR exhibits a linear relationship with compressive strength and a power exponential relationship with splitting strength and rebound modulus.The conclusions can provide reference for pavement structure design and future research.
