... subgrade strains were recorded. Analyses of the rutting, FWD tests and shallow dynamic subgrade strain behaviour are presented, leading to the general conclusion that the benefits of reduced tyre inflation pressure traffic seen in field implementations of CTI systems are derived more from the behaviour...

... evaluated. The rheological properties of mixtures were measured and the stress-strain relationships in model pavements were analysed. Mixtures with high viscosity had high strength, a high modulus, low compliance and a low rate of deformation, and consequently had high deformation resistance to wheel load...
