Tire Rubber Modified Asphalt Mixture Road Performance

As China's industrial and agricultural production and transportation development, discarded tires and various rubber products, waste more and more stock. 2004 reached 120 million, by 2010 will exceed 200 million. A large number of scrap tires are discarded, causing a serious waste of resources and environmental pollution. Address the large accumulation of waste tires caused by pollution and land use black issues, protection of the environment, alleviate the pressure of the shortage of national resources, is imminent.Tianjin, the third national identity as a growth pole, leading the Bohai economic circle, are high-speed economic development, transport system which is the most important, Expressway construction of a large area of the city will be significantly ease the traffic pressure, improve the city's overall structure, and the resulting negative impact caused by road builders attention: first, quick way to assume greater traffic flow, as Tianjin, the main road network skeleton, must ensure that its use function in a long time in good condition, should take measures to enhance the durability of asphalt pavement, high temperature stability, low temperature cracking, reducing the interference caused by road maintenance to reduce maintenance costs; Second, the rapid construction of road vehicles has greatly enhanced the speed of traffic will inevitably bring noise pollution to nearby residents, eliminate the noise must also be highly valued.To this end, the latest research results at home and abroad, through theoretical analysis, laboratory test, test road paving and outdoor testing, the status of pollution of the environment for waste tires, waste tire rubber modified asphalt mixture performance of the construction techniques were used studies to grade the road in the construction of Tianjin, a large area of applications received, pre-Tianjin Expressway Bridge Sunco test sections were paved, has been successful.
