橡胶颗粒沥青路面路用与除冰雪性能研究

论述了橡胶颗粒沥青路面自应力除冰雪的机理,并对其应用前景进行了展望。通过室内试验验证了橡胶颗粒沥青路面的路用性能和自应力除冰雪性能。试验表明,橡胶颗粒沥青路面在车辙性能、低温抗裂性能和抵抗水损害性能等方面均能达到或超过普通沥青混合料的各项性能指标;在自应力除冰雪方面优于普通沥青混合料的性能。

Research of Pavement and Anti -ice -snow Performance of Granulated Crumb Rubber Asphalt Pavement

The snow on the common phenomenon, and road and frozen phenomenon in timely and effectively removing portant practical significance to the safeguard north frost region of China are most pavement snow and ice has the im- of the traffic safety, and improves the traffic capacity. The anti - ice - snow mechanism of self stress of the granulated crumb rubber asphalt pavement is discussed, and type and method of anti - ice - snow technology are explored at the current road pavement. Its good mechanical properties and road performance are verified by indoor test. And the present situation and application prospect are looked forward to. Experiment resuits show that anti - rutting performance, low temperature anti - cracking performance, anti - water damage and so on of the granulated crumb rubber asphalt pavement are equal to or better than that of the common asphalt mixture, and adaptive anti - ice - snow performance of the former outperforms that of the later.
