冷铺沥青材料的特性与配制技术

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。

Property of Asphalt Material Cold - Paved and Disposing Techniques

Repairing the chuck holes of pavement with cold - paved asphalt mix possesses the merits of convenience,quickness etc. In order to ensure its ravel and compactness, the mix differs greatly from hot - mixed asphalt mix in its disposing methods for example the viscosity of asphalt, dosage of asphalt, additive as well as grading of aggregate. Practice shows that the cold - paved material developed has a good service performance, its cost has been greatly lowered over one of similar material imported.
