沥青混合料高温稳定性影响因素及改善措施

The Factors Affect the High-temperature Stability of the Asphalt Mixture and the Improvement Measures

分析影响沥青混合料高温稳定性的因素,针对沥青路面面层的沥青混合料,通过试验数据、国内外研究现状,从级配、矿粉性质、粉油比、沥青类型、沥青用量、压实度、荷载情况、气候条件、SMA沥青混凝土、施工等方面分析改善沥青混合料高温稳定性的机理,为沥青路面设计、施工提供参考。

This paper analyses the factors affect the high-temperature stability of the asphalt mixture for the asphalt pavement. Through the test data, research data at home and abroad, from grading, slag nature, the oil, the type of asphalt, asphalt content,compactness, load, weather conditions, SMA asphalt con- crete, construction and other aspects of high-temperature asphalt mixture to improve the stability of the mechanism for the asphalt pavement. It gives use reference in design and construction.
