摘要/Abstract

摘要： 为探究高模量天然沥青混合料的设计方法及路用性能,选取高模量天然沥青(HMB),利用修正马歇尔设计法制备了高模量天然沥青混合料BBME-13(béton bitumineux à module elevé-13),分析了其马歇尔体积指标及内部结构,并对比研究了其与SBS改性沥青混合料SBSAC-13和基质沥青混合料SKAC-13的路用性能差异,最后通过试验段铺筑验证了其适用性。研究结果表明:BBME-13的油石比、稳定度和动态模量均显著高于SBSAC-13和SKAC-13;BBME-13的动稳定度、残留稳定度和冻断强度代表值分别比SBSAC-13增大32.2%、9.0%和45.5%,分别比SKAC-13增大148.3%、19.6%和93.2%;BBME-13的最大弯拉应变的代表值比SBSAC-13减小3.3%,比SKAC-13增大34.4%;BBME-13试验段路面抗渗性能优异,抗滑性和压实度等也均能满足规范要求。

Abstract: To explore the design method and road performance of high modulus natural asphalt mixture, the following works were done: high modulus natural asphalt HMB was selected, and high modulus natural asphalt mixture BBME-13 (béton bitumineux à module elevé-13) was prepared by modified Marshall design method. The Marshall volume index and internal structure of the asphalt mixture were analyzed, and the road performance differences of the asphalt mixture with SBS modified asphalt mixture SBSAC-13 and base asphalt mixture SKAC-13 were compared. The applicability of BBME-13 was verified by the construction of test section. The results show that the asphalt aggregate ratio, stability, and dynamic modulus of BBME-13 are significantly higher than those of SBSAC-13 and SKAC-13. The representative values of dynamic stability, residual stability and freezing breaking strength of BBME-13 are 32.2%, 9.0% and 45.5% higher than SBSAC-13, 148.3%, 19.6% and 93.2% higher than SKAC-13, respectively.The maximum flexural strain of BBME-13 is 3.3% less than that of SBSAC-13, and 34.4% more than that of SKAC-13. The pavement of BBME-13 test section has excellent impermeability, and its skid resistance and compactness can also meet the requirements of the specification.
