微表处技术在高速公路养护中的应用

On Micro-surfacing Technique Applied in the Expressway Maintenance

微表处是一种性能优良的路面养护技术。结合微表处在某高速公路养护中的应用,探讨了微表处改性乳化沥青、集料、填料和水等材料的选用,配合比设计,以及施工工艺。该项技术在无结构病害的路段进行推广与应用,具有良好的经济效益和社会效益。

The micro-surfacing technique is ragarded as a pavement maintenance technique with excellent performance.With the technique applied in some expressway maintenance,the choice of the material(modified emulsion asphalt,aggregate,filler and water),mixing proportion and the construction technique have been discussed.The technique has been proved of good economic and social benefits through its popularizing and application in the road section without structure disease.
