Pavement, rail track and airfield materials include bitumen, asphalt, hydraulically bound materials, unbound granular materials and soils.

Research activities address the key distress mechanisms of flow and plastic deformation; cracking and fracture; and environmental damage.

Research

Key growth areas include micro-structural characterisation using X-Ray Computer Tomography (CT) and physico-chemical analysis of the material components and their respecitve interfaces. This is of critical importance since the bulk mechanical properties of particulate materials depend on the structural and mechanical properties of the individual particles and the combined physical and chemical processes acting between them.

 

Research aims

  • Characterisation of foam bitumen and hydraulic stabilised materials for use in pavements and airfields
  • Development of a combined moisture/ageing durability test
  • Investigation of interlayer bond
  • Elasto-plastic modelling of cyclic loading and application of 'Shakedown' theory to foundation materials
  • Fatigue and permanent deformation characteristics of bitumen-filler mastics, and asphalt mixtures
  • Resilient and permanent behaviour of unbound granular materials such as railway ballast and soils
  • Development of alternative asphalt mixture binders
  • Interfacial characterisation of bitumen-aggregate systems using surface activity measurements to address moisture damage of asphalt mixtures
