| 摘 要： | 在进行原材料指标和矿料级配研究基础上,进行了温拌沥青混合料的性能试验.结果表明,掺加3%Sasobit后,沥青混合料的高温稳定性增强.对于基质沥青,其混合料的低温抗裂性、抗疲劳性能有所下降;而改性沥青加入3%Sasobit后,其混合料的低温抗裂性、抗疲劳性能增强. |

| Abstract: | On the basis of researching indexes of raw and processed materials and mineral aggregate gradalion,performance test of warm-mixing asphalt mixture is carried out.Tested results indicates that admixing 30 percent of sasobit,the stability of asphalt mixtur at high-temp is heightened,but for maxtrix asphalt,the crack-resistance and fatigue-restance of its mixture at low-temp lower.As 30 percent of sasobit are admixed into modified asphalt,the crack-resistance and fatigue-resistance of mixture at low temp are s... |
