ELT Asphalt Mixtures

The Latin American Society of Tyre Technology (SLTC) is hosting its second Ibero-American course on using end-of-life tyres in asphalt mixtures, held virtually across five sessions in June 2026.

A Regional Effort on Rubberised Asphalt

Organised through the SLTC Recycling Committee, the course is coordinated by Lic. Karina Potarsky, the committee’s director, with academic leadership provided by Dr. Gerardo Botasso of UTN La Plata and the institution’s Rubberised Asphalt Subcommittee. The programme brings together public agencies, universities, companies, and specialists from several countries to address the technical and regulatory developments shaping the use of end-of-life tyres (ELTs) in asphalt mixtures.

Why ELT Asphalt Mixtures Matter

End-of-life tyres are a persistent waste challenge, and road construction offers one of the highest-volume outlets for recycled tyre rubber. To produce the material, whole tyres are shredded and ground — typically through ambient or cryogenic processes — into crumb rubber, which is then blended with bitumen and aggregate. The resulting rubberised asphalt can improve pavement durability, crack resistance, and skid resistance while measurably reducing traffic noise. Equally important, every length of rubberised asphalt placed diverts scrap tyres from stockpiles and landfill, converting a long-standing waste burden into a durable, high-value construction material.

Crumb Rubber and the Circular Economy

Rubberised asphalt is a major consumer of crumb rubber, but it sits within a wider network of tyre-recovery pathways. Klean Industries supports this space through tire pyrolysis, which thermally converts scrap tyres into recovered fuel oil and char, and through recovered carbon black, a co-product that can be compounded into new rubber and plastics. When crumb rubber, pyrolysis products, and recovered carbon black are developed side by side, the industry captures far more of the tyre’s material value than any single route alone, keeping tyre-derived materials in productive use instead of letting them go to waste.

Building Regional Capacity

Training and knowledge-sharing initiatives such as this course matter because they equip regulators, road agencies, and engineers with the practical know-how to specify and adopt rubberised asphalt with confidence. For operators and project developers, a rigorous feasibility study is the essential first step in evaluating how tyre-derived materials fit a given road network or regional recycling strategy.

Put ELT Asphalt Mixtures to Work

Rubberised asphalt and crumb rubber give road builders a proven way to strengthen pavements while consuming scrap tyres at scale. Klean Industries supports the full value chain, from tyre recovery and pyrolysis to recovered carbon black and project feasibility.
