溶剂型冷补沥青混合料矿料级配组成设计研究

Study on the gradation composition design of the solvent cold patching asphalt mixture

通过冷补沥青混合料工作性、初始强度及空隙率等试验研究,分析了不同类型级配冷补沥青混合料的技术参数,提出冷补沥青混合料最佳级配组成。结果表明,在满足工作性要求下,改进型骨架空隙型冷补沥青混合料具有更好的初始强度及空隙率参数,能够有效保证冷补沥青混合料的长期使用耐久性。

Based on the experimental study on the workability, the initial strength and the void fraction of cold patching asphalt mixture, the technical parameters of different types of cold mix asphalt mixture are analyzed. The results show that to meet the work requirements, improved the skeleton void type cold mixture has better initial strength and void rate parameters of asphalt, which can ensure the long - term durability of Cold Patch Asphalt mixture.
