Projects related to the micromechanics of bitumens and asphalts
An exciting area of research in the department is a multi-disciplinary project
investigating the micromechanics and failure mechanisms of asphaltic pavement materials. Experts in materials science, fracture
mechanics, powder compaction, polymer composites, rolling contact, soil mechanics, and vehicle-road
interaction; as well as pavement engineers from Nottingham University are collaborating on the project. The
research is investigating asphalt deformation and fracture from a fundamental micro-mechanical perspective.
Initial work has concentrated on the behaviour of pure bitumens, measured over a very wide range of operating
conditions, as well as the performance of idealised asphalt mixes consisting of known aggregates mixed with
bitumen. The work has so far produced fascinating new insights into the deformation and fracture behaviour of asphaltic materials, and
the researchers are hopeful of eventually being able to develop new, less empirical methods of road mix
design.
