“Crumbing” up with a solution for cracked roads

18/07/2019  Here, the high viscosity of the crumb rubber modified binder allows higher binder contents to be used in open graded asphalt, without the binder draining down. The presence of carbon black in combination with a thick film of binder retards oxidation and increases the life span of open graded asphalt. Overall, this makes for lower maintenance costs and more durable roads.

Making the Case for Rubber Roads Agg-Net

‘Crumb rubber can be successfully incorporated into asphalt mixtures to create innovative mix designs, and these are now being used in the EU. These technologies are known as the ‘dry’ or ‘semi-wet’ process and do not require adaptations to asphalt plants. However, they are still not considered a viable option when it comes to building roads.’

How Rubberized Asphalt Is Changing Our Roads

22/04/2021  The program’s goal was to investigate whether rubberized asphalt could reduce road noise enough to eliminate the need for sound barriers on major roads. After one year, the evidence was clear. Adding crumb rubber to the streets significantly decreased the noise produced by passing cars up to 12 decibels. Its ability to reduce road noise would make rubberized asphalt more appealing to other ...
