Engineers to use Biochar to Make Asphalt Roads More Sustainable

Apr 30, 2024

  • Aston University experts are working with road surfacing specialist Miles Macadam
  • The project aims to find a more sustainable alternative to traditional fly ash
  • The two organisations have entered a knowledge transfer partnership (KTP), a collaboration between a business, an academic partner and a highly qualified researcher.

Aston University civil engineering experts are teaming up with construction and surfacing company Miles Macadam to help make road surfaces more sustainable.

The University has entered a knowledge transfer partnership (KTP) with the Cheshire-based firm, which manufactures and installs ‘grouted macadam’, an asphalt and cement-based material for road and industrial surfacing.

A KTP is a three-way collaboration between a business, an academic partner and a highly qualified researcher, known as a KTP associate. The UK-wide programme helps businesses to improve their competitiveness and productivity through the better use of knowledge, technology and skills. 

Aston University is a sector-leading knowledge transfer partnership provider, with 80% of its completed projects being graded as very good or outstanding by Innovate UK, the national body.

The grouts that Miles Macadam use in their surfacing products contain fly ash, a waste product from coal-fired power stations, which now has to be imported. As a result, the quality of this fly ash is variable and the supply can be erratic. Miles Macadam is collaborating with the University to find a more sustainable alternative.
