摘　　要：为分析SRX聚合物稳定碎石的路用性能,通过室内试验对抗压强度、CBR、动稳定度、温缩系数、干缩系数等指标进行测试。结果显示:SRX聚合物稳定碎石的CBR、抗压强度均随SRX用量的提高而呈增大趋势,CBR、抗压强度均与SRX用量呈二次函数关系。根据SRX用量和级配等情况,采用本研究拟合关系式可预估CBR和抗压强度值;SRX聚合物稳定碎石具有较高的强度和动稳定度、较小的温缩系数及干缩系数,可在道路基层中应用。In order to analyze the road performance of SRX polymer stabilized macadam,the compressive strength,CBR,dynamic stability,temperature shrinkage coefficient and dry shrinkage coefficient were tested through indoor test.The results showed that the trend of CBR and compressive strength increased with the enhanceding of SRX.Both CBR and compressive strength were quadratically related to the amount of SRX.According to the dosage and gradation of SRX,the fitting relationship was used to estimate the CBR and compressive strength values.The SRX polymer stabilized macadam had high strength and dynamic stability,small temperature shrinkage and dry shrinkage coefficient,which could be applied in the road base.
