中文摘要：

针对大粒径透水沥青混合料，采用overlay tester试验，根据荷载周期数、最大荷载损失率、总断裂能、第1周期最大荷载、第1周期最大荷载处位移及第1周期断裂能等指标综合评估其抗反射开裂能力。结果表明，用overlay tester试验测得的荷载周期数、最大荷载损失率可综合反映沥青混合料抗裂性，结果变异性较小；而总断裂能及第l周期指标不能全面准确反映沥青混合料抗裂性；低温及温差较大时橡胶粉改性沥青大粒径混合料抗裂性更佳；overlay tester试验周期-最大荷载曲线符合幂函数变化规律。

英文摘要：

In order to investigate the cracking-resistance potencial of large stone permeable asphalt, the overlay tester was used and several indexes including the number of test cycles, the load loss rate, the total fracture energy, the maximum load of the first cycle, the displacement at the maximum load of the first cycle and the first periodic fracture energy were analyzed. Results show thatthe test number and load loss rate can he combined to reflect the crack resistance of asphalt mixture by OT and results show small variability, while the remaining indicators cannot fully reflect asphalt mixture＇s performance. The rubber modified aspahlt mixture shows better crack resistance at low temperature or when the temperaturedifference is large.Thecurve of test cycle and maximum load conforms to the law of power function.
