Study On The Maintenance Technology Of Micro Surfacing In Shanxi Expressway

Micro-surface conservation technology has been applied in China for many years,with its convenient and efficient and economical welcome,its application can be simple to deal with the road rut,pits,water damage and some other diseases,but also when the road in good During the period of use,preventive maintenance is carried out in a timely manner to prevent overhaul of the road after severe damage,to improve the service life of the road and to save the life cycle cost.Based on the characteristics of traffic conditions in Shanxi area,local climatic environment and other conditions,the reasonable suggestions for improvement of micro-surface raw materials in Shanxi Province were put forward and the matching design method of mixed materials was put forward.And put forward a complete set of micro-surface construction technology for Shanxi micro-surface construction provides a reference.The optimal timing of microfabrication is studied,and a comprehensive evaluation index based on performance is proposed.Combined with the prediction model of road performance decay,the best time of curing is determined.Relying on the original too highways,micro-surface technology in Shanxi area application,the effect is good.,For the follow-up micro-surface conservation to provide a case,played a reference role.
