Improved Laboratory Characterisation of the Deformation Properties of Granular Materials

This report examines the capacity of the extra-large wheel-tracking laboratory test method to predict the in-service performance of granular materials.

Rutting is a common distress mode of unbound granular bases under thin bituminous surfacings.

Long-term Ageing Resistance of Bitumen using the Pressure Ageing Vessel (PAV) and the Dynamic Shear Rheometer (DSR)
This test method sets out the procedures for the ageing treatment of bitumen samples under specific conditions using the Pressure Ageing Vessel (PAV), and also the determination of the complex viscosity of treated samples under specific conditionsā€¦
