用冷铺沥青混合料修补路面坑洞 ,具有方便、快捷等优点。为保证其疏松性和压实性 ,在配制方法上 ,如所用沥青的粘度、沥青的用量、添加剂以及集料级配等 ,与热拌沥青混合料都有很大区别。实践表明 ,所研制开发的冷铺材料使用性能良好 ,而成本却比同类进口材料大大降低。 With cold paving asphalt mixture repair road potholes, with convenient, fast and so on. In order to ensure its looseness and compaction, in the preparation methods, such as the viscosity of asphalt used, the amount of asphalt, additives and aggregate gradation, and hot mix asphalt mixture are very different. Practice shows that the performance of cold-laid materials developed by the company is good, while the cost is much lower than the imported materials of the same kind.
