Study On The Timing And Construction Applications Of Micro-surfacing Treatment For Rutting Pavement

Preventive maintenance of existing road system plan is a good road to take, based on cost-effectiveness of conservation strategies. Micro-surfacing gradually been widely used in recent years as preventive maintenance technology, has a good advantage for the Treatment of Rut road. This paper briefly describes the technical characteristics of the micro-surfacing, and select Expressway Rut road and slurry seal comparative advantage, research, analysis and calculation to take the economic benefits of micro-surfacing, the benefit-cost ratio method The optimal timing of conservation. Secondly, according to the local socio-economic situation, it is reasonable drawn Mixture Ratio Design. Finally, the Jinan-Qingdao micro-surfacing asphalt pavement maintenance and construction, construction in the best timing of conservation, the actual operation of the process of its construction. Through the construction process and effect evaluation, indicating that local materials in micro-surfacing mix the good ruts repair effect, meet the requirements of road performance. But in the different construction conditions, but also needs to proceed with the collection of test data, efficacy evaluation and follow-up research work. The conclusion of the study the conditions of different regions, drawing different micro-surfacing maintenance and construction has a larger role in guiding and certain theoretical reference value.
