摘要
通过马歇尔试验确定不同纤维用量的沥青混合料的最佳沥青用量,并探讨了马歇尔试验指标的变化规律。在低温弯曲蠕变试验和低温弯曲试验中,通过低温弯曲蠕变速率和低温劲度模量进一步验证聚酯纤维沥青混合料的低温抗裂性能,并分析了聚酯纤维加强沥青混合料作用机理。
The best asphalt dosage were anticipated by the asphalt mixture that Matthus experiments with different fiber dosage, and discussed the regulation of Matthus experiment index. In the low temperature flection and creep deformation experinaent, the low temperature anti - funetion changed the velocity and the low temperature strength mold quantity a further verification the polyester fiber asphalt mixture to anticipate through the low temperature flection, and analyzed the polyester fiber to strengthen the asphalt mixture to anticipate function mechanism.
