Waste tire rubber modified asphalt is the best form of recycling

Production of Rubber Fine Powder Grinder manufacturer rubber modified asphalt has been applied in laying Yangzhong old S238 Provincial Highway Road and other roads in the three columns, and now the completion of road about 45 km, using the mixture of about 5500 tons, the equivalent of recycling of 110,000 cars home waste tires, not only solved the problem of environmental pollution waste tires, also produced some economic benefits, only from 2012 to 2014, the total output value as high as 150 million yuan.

According to statistics, China's tyre debeader for sale in 2014 more than 562 million, and produce about 10 million tons of waste tires, and 5% to 6% annual growth rate. Large accumulation of waste tires, not only can not automatically degradation, occupation of land resources, there are also a risk of fire, the breeding of mosquitoes and other risks. How to properly dispose of these solid waste, become problems facing countries in the world.

Indeed, waste tyre dispose machine waste tires is not without merit, but also full of treasure: containing up to nearly 60 percent of the rubber mixture, it is a rubber mixture containing waste tires.

According to experts, the current treatment of waste tyre dispose device are the following: the prototype direct use, thermal decomposition, renovation of old tires, production of recycled rubber and vulcanized rubber powder. In these types of treatment method, using waste tire rubber modified asphalt is the best form of utilization of the development of circular economy.

This is because the use of crumb rubber modified asphalt paving, asphalt will not only enhance high temperature stability, low temperature crack resistance, anti-aging and durability, but also to replace the current widely used and expensive styrene - butadiene - benzene ethylene copolymer (SBS) and styrene-butadiene rubber polymer modifiers, reduce road construction costs, save oil resources.

"Compared to the SBS modified asphalt, rubber modified asphalt is not only lower costs, anti-rutting ability to aggregate also better." Experts.
