Research On Technology Application Of Medium-capital Overhauling Of G314 Line Bituminous Pavement

This project mainly focuses on the application of the G314 line to carry out large-and medium-sized road repair works.G314 Line is the national highway,it is starting for Urumqi and the terminal is Khunjerab in Xinjiang.The route extends from the north to the south,and by the way of Korla? Aksu? Kashgar.The long is 1948 km.With the increase of road transportation demand in the area covered by the G314 Line,the rapid increase in traffic volume,the increasing pressure on transportation,accompanied by the overload of overloaded vehicles,and the adverse natural environment and geographical conditions,G314 have the serious roadbed and road surface diseases,and concentrated on local road sections and have begun to affect the normal passage and operation of roads,and also seriously affect the road safety;it is necessary to carry out major repairs on the road surface to ensure the traffic safety of the G314 Line.Based on the further extension of the road's service life.Based on the preliminary analysis of the natural geographic location,road traffic and daily maintenance status of the G314 Line,the paper uses artificial walking,mechanical equipment,core drilling and digging surveys,etc.A comprehensive investigation and analysis was conducted on the asphalt pavement section,and the road condition,driving quality,rutting and structural strength of the G314 Line.Based on this,designed the Program of asphalt pavement repair about G314 Line.Finally,carry out construction of the asphalt pavement on the G314 Line.Therefore,this Dazhong modification will greatly improve the G314 road traffic conditions,improve its use of functions,improve the road network structure,and has important construction significance.
