摘要:
对硬沥青混合料、70#沥青混合料、SBS改性沥青混合料分别进行高温稳定性(为0.7 MPa下50 ℃、60 ℃、70℃3个温度状况下的车辙试验)、低温抗裂性(小梁低温弯曲试验)、水稳性(冻融劈裂试验、残留稳定度试验)、疲劳性能(APA疲劳试验)的全面对比试验.试验结果表明,高模量沥青混合料具有较好的抗车辙性能;在-5℃时极限荷载约14 000 N,表明了其仍然具有良好的低温抗裂性能;冻融劈裂试验表明,AC-20C(30#)沥青混合料具有高的冻融劈裂强度比,具有较好的水稳定性.
Abstract:
Aim to the hard asphalt mixture，70#asphalt mixture，SBS modified asphalt mixture were heat—stable(for the 0．7 MPa under 50℃、60℃、70℃three temperature conditions of the rutting test)，low tem—perature crack resistance(trabecular low temperature bending test)，water stability(freeze—thaw fracturingtests，residual stability test)，fatigue performance(APA fatigue test)．the results show that，High modulusasphalt mixtures have better resistance to rutting performance．as the limit load is about 14 000 N．at一5℃the high modulus asphalt mixture still has a good low—temperature anti—cracking performance．Freeze—thaw splitting results showed that AC一20C(30#)asphah mixture with a high intensity ratio of the freeze—thaw cleavage，with good water stability．
