Car total kilometrage breaks through 4,500,000 kilometers, and wherein highway mileage open to traffic reaches 10.8 ten thousand kilometers, and highway in China road network scale occupies
The first in the world.The construction of a large amount of highway facilitieses consumes a large amount of valuable natural resources, has not only broken up natural environment, Er Qiejia
Weigh resource environment bearing load；Natural resources is petered out, and the mankind are that contention resource occurs the phenomenon of opposition to get more and more；?
Highway facilities big or middle produces substantial amounts of waste and old ground surface material in repairing and reconstructing, and substantial amounts of waste and scrap generally uses landfill etc. to arrange
Execute and process, occupy limited land resource, environment is produced and pollutes, cause the substantial amounts of wasting of resources simultaneously.
According to the preliminary statistics, China's only arterial highway medium-capital overhauling engineering, every year generation old material of asphalt pavement is reached 1.6 hundred million tons, cement
The old material in road surface reaches 30,000,000 tons.But, current highway in China ground surface material cyclic utilization rate is less than 30%, far below developed country
90% rate level utilized above, away from Department of Transportation's " about accelerating to advance the instruction of highway pavement closed matereial cycle work "
What ([2012] 489# is sent out on road of handing over to the collective or the state) proposed reaches 50% to " 12 " end highway pavement waste and scrap cyclic utilization rate, height
Speed old road ground surface material cyclic utilization rate reaches the target of more than 90% also many gaps.To this end, Department of Transportation " ten
Two or five " environmental protection planning proposes to utilize demonstration highway, regenerating waste asphalt to utilize demonstration emphasis building constructions recycle respectively
Highway is not less than 1000 kilometers.Therefore, the work that recycles accelerating highway pavement waste and scrap is imminent, and to promotion
