Our research on waste and biomass derived bitumen for road applicaiton is reported in media

Could the roads of the future be bio-based?Bitumen is a by-product of oil production and is used to bind the surfaces of paved roads. Some researchers, concerned about its environmental impacts and future supply if petroleum refining slows down, ...

Bio-bitumen research is reported in media

Scientists use domestic waste for greener roads | Planning & Building Control TodayScientists at Aston University in Birmingham have developed a way to transform ordinary domestic waste into material suitable for laying roads and pavements

Impact of minerals and water on bitumen-mineral adhesion and debonding behaviours using molecular dynamics simulations

Adhesion between bitumen and aggregate mainly results from van der Waals internations for neutral minerals (e.g., quartz)
Adhesion is primarily due to the electrostatic interactions for alkali minerals (e.g., calcite, albite and microcline)
The bitumen-mineral debonding due to water is a thermodynamically favourable process.

Modelling cracking damage of asphalt mixtures under compressive monotonic and repeated loads using pseudo J-integral Paris’ law

Pseudo J-integral Paris' law coefficients proved to be material properties, independent of loading rate, loading mode and temperature
You can determine the Paris' law coefficients using a monotonic load, rather than a time-consuming repeated load.
