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. Five granular bases were tested for rut-resistance under accelerated loading and the results compared to a number of laboratory characterisation tests. The laboratory tests included large-scale wheel tracking, repeat load triaxial and shear strength. It was concluded that the large-scale wheel-tracking test was the best available test to rank granular base rut-resistance. It is a useful performance-based test, which can lead to significant cost saving by optimising the use of otherwise non-traditional locally available aggregate resources.
