The US Tire Manufacturers Association (USTMA), in collaboration with The Ray – a non-profit company for sustainable transport technologies – have announced  a research project to evaluate the performances, the environmental impacts, and the advantages linked to the use of asphalts modified with rubber recycled from ELTs- End-of-Life Tyres.

The research will provide a report on the “state-of-the-art” of all existing research related to the sector of asphalts modified with rubber recycled from ELTs. The aim is to have an in-depth knowledge of this valid application of recycled rubber.

Asphalts modified with rubber recycled from ELTs allow to make long-lasting, safe, and silent roads. The interest towards this application is constantly growing also in Italy thanks to its exceptional properties: a reduction of up to 5 dB of the noise generated by the passing vehicles, and a duration that is up to 3 times the one of conventional asphalts, thanks to its greater resistance to wear and the formation of cracks and potholes. This aspect also allows a subsequent reduction of maintenance costs in the medium-long period.

Dr. Bill Buttlar, Director of the Missouri Center for Transportation Innovation, will lead the study in collaboration with a team of technical consultants composed of scientists, researchers, and experts of the sector.

The results of the study should be published in spring 2021.
