沥青道路材料指标性能分析

Performance Analysis and Evaluation of Asphalt Road Materials

随着我国高速公路快速发展,对道路材料的指标性能提出了越来越高的要求。沥青材料优良直接关系道路的质量安全和使用寿命,该文在国内外学者关于沥青材料性能的研究成果基础上,采用的沥青材料通常面临不同指标对比之间的差异,通过对不同种类的沥青的性能进行比较分析,得到改性前后沥青材料指标性能的变化情况。研究结果显示,温度变化对沥青材料的性能有着显著影响,根据地区温度变化的指标权重对不同种类的基础材料进行判别,研究结果对高速道路质量控制提供科学依据。

With the rapid development of highways in China,higher and higher requirements have been placed on the index performance of road materials.Asphalt materials are directly related to the quality and life of roads.Based on the research results of domestic and foreign scholars on the performance of asphalt materials,the asphalt materials used usually face the difference between the comparison of different indicators.The performance is compared and analyzed to obtain the change of the index performance of the asphalt material before and after modification.The research results show that temperature changes have a significant impact on the performance of asphalt materials.According to the index weights of regional temperature changes,different types of basic materials are distinguished.The research results provide a scientific basis for the quality control of highways.
