Researchers Discover A Way To Build Durable Roads By Using Waste Tires

Since decades researchers are trying to find out ways for recycling the waste material, the recycling projects for waste materials are mainly done on massive scales. Besides, to get something new out of the waste materials, the all-new process involves cleaning our planet at large.

An Australian based team of Engineers came up with the marvelous mix for recycled road construction material. It involves old tires waste along with the rubble from construction sites. The blended material was tested and proven to have immense strength and flexibility to handle heavy traffics. The all-new road construction material will cost less and will be more longlasting in terms of road durability.

The researchers pointed on the massive amounts of waste generated by construction, renovation, and especially demolishing practices. On the other hand, tonnes of tires waste is produced worldwide. They just combined them both!

Crushed building rubble is called recycled concrete aggregate and can be mixed with other building materials waste to preserve our environment. In road construction, RCA (recycled concrete aggregate) can act as the base layer that sits above the sub-base layer of crumb rubber taken from scrap tires.

While its research on RCA integrated with different other materials, the team found that 0.5 percent of fine crumb rubber mixed with 99.5 percent recycled concrete aggregate will leave us full of strength, road construction material.

This is so far the best mix of rubber and rubble, which offers better flexibility compared to conventional road construction materials. In addition to becoming a milestone in recycling-related projects, the material is said to be precisely optimum for meeting the road safety standards. Cars will have a better grip on the road built with these waste materials.

The researchers say, along with providing benefits of cheaper and greener roads construction, it also enabled us to build roads with fewer cracks in the longer run.

Traditional road bases are made of unsustainable materials – inclusive of forms of rocks and natural sand,” says lead researcher Dr. Mohammad Boroujeni. “Our blended material is a 100-percent recycled alternative that offers a new way to reuse tire and building waste while performing strongly on key criteria like flexibility, strength, and permanent deformation. As we push towards a circular economy that can eliminate waste and support the continued use of resources, our recycled blend is the right choice for better roads and a better environment.”
