摘要
通过采用GTM方法和马歇尔方法对AC-13上、中、下限和AC-16中值等四种级配的沥青混合料进行配合比设计,可确定最佳沥青用量。室内关于四种混合料在最佳沥青用量时的低温抗弯拉强度、低温应变和应变能等指标的测试结果表明,采用GTM方法设计的沥青混合料具有良好的低温路用性能。
Four gradations of asphalt mixture like upper, medium and lower limit of AC-13 and AC- 16 medium are studied on the mixture ratio through GTM method and Marshall method, thus determining the optimal asphalt content. The four kinds of mixture is tested indoor in low-temperature anti-flexuraltensile strength, low temperature strain and strain energy. The test results show that asphalt mixture designed through GTM method has excellent low-temoerature road nerformance.
