冷补沥青混合料的配比设计

与热拌沥青混合料相比，冷补沥青混合料由于不受天气条件限制，能随用随补，成为目前公路沥青路面坑槽修补的一种新形式。针对冷补沥青混合料的配比问题，选择了冷补沥青混合料的原材料，研究了冷补沥青添加荆的配方，对冷补沥青混合科初始强度和成型强度进行了试验。试验结果表明，所配制的冷补沥青混合料有较好的性能。

Proportion Design of the Cold Fill Asphalt Mixture

Compared with hot-mix asphalt mixture, cold fill asphalt mixture can be used with no regard to the weather and time and has become a new form of filling the pits of road pavement. Considering the mixing proportion and raw materials of the mixture, the paper studies the mixing and tests initial strength and forming strength, the result shows that the mixture of the proportion has better performance.
