Application And Research Of Weifang City Road Surface

Over the past decade, rapid social and economicdevelopment, urban constructionby leaps and bounds, municipalroadnetwork continues to improve.With the rapid development of Weifang city economy in recent years, but also grow with each passing day city road construction, now the road mileage is about565kilometers, the new and old road coexist, most of the road going into the overhaul period, in order to better do road maintenance management, improve maintenance quality, cost saving, the city began in2011the micro surfacing technology introduced to the maintenance and management of city road.Micro surfacing is mainly suitable for important traffic road preventive maintenance such as highway, city trunk road, airport runway, is waterproof, wear, improve the skid resistance of pavement, many advantages/beautiful degree, prevent aging and loose, pavement fill has stable rutting, open environmental traffic is short, etc.This paper will summarize the engineering problem of road of Weifang City, the application of micro surfacing technology, from the micro surfacing the preparation work before construction, material, mix proportion, construction process control and analysis of common problems and other aspects, to optimize the city road of micro surfacing construction parameters and procedure, as the micro surfacing later better service city road maintenance for reference, to improve the quality of road use, prolong the service life of roads...
