稀浆封层在公路养护中的应用

Application of Thin-Flowing Seal in Highway Maintenance

稀浆封层具有提高路面的防水、防滑、耐磨性能,能改善路面平整度,延长路面使用寿命,降低路面养护成本,施工方便等优点。它适用于沥青和水泥路面的预防性养护和网裂、贫油、麻面等病害路面的修补。叙述了以花岗岩为骨料的乳化沥青稀浆封层在现代公路养护中的应用,并结合工程实际对该技术从材料到施工进行了探讨。

Emulsified-asphalt thin-flowing seal not only have the advantage to improve the watertight, the skid resistance, the wearability and improve the flatness of road surface, but also, it can prolong the life span of pavement and it have the superiority in the construction or investment. Emulsified-asphalt thin-flowing seal can be used in asphalt pavement and cement concrete pavement by preventing maintenance or revamping in the disease of net-split, lean oil, numb surface and so on. The use of emulsified-asphalt thin-flowing seal with granite aggregate in modern highway maintenance was introduced. Also, combined with engineering project, the technology was studied the from material to construction.
