Green Tire Pavement Construction Technology
Already used tire when recycled then tires improves asphalt pavement quality while utilizing an unwanted used waste by-product of the transportation industry and highway construction.
What is Rubber Road?
The annual production numbers show over 200 million tires manufactured globally for automobiles, trucks, farm equipment, and recreational vehicles reflect as a high demand of tire. Whenever these tires wear out ,then need to be to be throw them away at a waste product, try to reuse the worn second hand tires architecturally, or last option is to chop /grind them up evenly and reuse as a raw materials for other products. Now such product reuse and adds the grindings into the binder portion of asphalt paving mixture content. Well grinded fine rubber particles at first stage screened to remove small bits of metal, plastic, and other non-rubber components which used in tire manufacture. Then the rubber bits are mixed well into the liquid asphalt binder at a extreme temperature to swell and react physically and chemically the rubber with the binder material. It helps to keep the bits suspended in the liquid binder material until it is mixed well with the usual coarse aggregates and sand at the asphalt bitumen concrete mixing plant. The resultant product is called Rubber Modified Asphalt Concrete (RMAC) and it is used in a various of pavement construction applications.
Advantages of Scrap Tires use in Pavement construction
Proper grinding of these scrap tires uses heavy effort and energy. It was observed that for making few inches of RMAC overlay can use over 1700 tires required per lane per mile. Also not only does this process recycle is tough but sometimes very dangerous eye and health hazardous but the constructing pavements have other many advantages.
- It is quieter and reducing the necessity for sound wall construction along busy roadways or highways.
- They are very much durable and less chances to fatigue cracking which can improve the lifespan of pavement and reduces regular basis maintenance costs.
- Pavement can be made more porous to drain out the water below and away from the pavement surface level.
