Asphalt Rubber Plant
An asphalt rubber plant is a specialized facility used in the production of rubberized asphalt. Asphalt rubber plants are important in sustainable construction practices as they help recycle used tires and reduce the demand for virgin asphalt. They play a crucial role in road construction and maintenance projects, providing a more environmentally friendly and longer-lasting alternative to traditional asphalt.

Brief Introduction
LXJ Series asphalt rubber plants are used to produce rubberized asphalt concrete (RAC). Rubberized asphalt is a special pavement material consisting of approximately 75-80 percent regular asphalt with 20 percent (+/-2%) crumb rubber made from scrap tires. Rubber asphalt overlays on road surface make road smoother, effectively reduce traffic noise and prolong road service time, having bright future and wide application in highway construction. Meanwhile, rubber asphalt plant recycles a large number of scrap tyres, helping to save resources and reduce pollution.

Working Principle of Asphalt Rubber Plants
Crumb rubber made from scrap tires is loaded into the hopper before mixing begins and must be replenished during the mixing process. Next the screw conveyor carries the crumb rubber to the mixing chamber. Then, the crumb rubber is blended with virgin asphalt by a high shear mixer running at a speed of 3400 rpm. As the materials are mixed, they are pumped to the portable holding tank. During the mixing process, fresh materials are continuously fed into the chamber until the required volume of material has been mixed.
