微表处配比在杭宁沥青路面养护中的应用研究

微表处技术作为国内高级路面养护的一种新技术,具有施工工艺简单,成本低,污染小,开放交通快等优点。该文结合微表处技术在杭宁高速公路路面养护中的应用情况,探讨了微表处沥青混合料的配合比设计问题,介绍了施工工艺过程。结果表明,采用MS-3型混合料配比进行现场施工控制是可行的,并通过了实践检验。

Study of Application of Surface Micro-treatment Mixture Ratio in Curing Asphalt Pavement of Hangning Expressway

The surface micro-treatment technique, taken as a new high-quality technique of pavement curing in China, has the advantages of simple construction technology, low cost, a little pollution and quick opening of traffic. Combined with the applying condition of the surface micro-treatment technique in curing the pavement of Hangning Expressway, the article approaches and discusses the design of the mixture ratio of the asphalt mixture of the surface micro-treatment, introduces the process of construction technology. The result makes clearly that it is feasible to use MS-3 mixture ratio for the control of the field construction and to pass the practical inspection.
