Abstract: A series of comparing tests has been performed of shanjiasi bituminous and import bituminous mixture using the wheel tracking test machine made in china.It is proved that the wheel tracking test is a reliable testing method used to evaluate the high temperature stability of bituminous mixture,and shanjiasi bitumen has approached to import bituminous mixture in high temperature properties.It is found that temperature,the thickness of specimens,the ratio of bitumen to aggregates,penetration index and degrees for aggregates have a larger effect upon dynamic stability.The evolution of rutting obeys power function model.

Key words: bituminous mixture, rutting, wheel tracking testing, dynamic sta-bility

摘要： 用国产车辙试验机分别对国产单家寺沥青及进口沥青混合料进行了对比试验。证明车辙试验是检验沥青混合料高温稳定性的可靠手段。单家寺沥青的高温性能已接近同标号的阿尔巴尼亚沥青。温度、试件厚度、沥青用量、沥青的针入度指数以及矿料级配等都对动稳定度有较大的影响。车辙深度按幂函数型数学模式发展。
