... to investigate the behaviour of unbound roads subjected to heavy wheel loads using low tyre inflation pressures. It is hoped that the research will aid in the development of procedures for the design of unbound roads used by vehicles equipped with central tyre inflation (CTI) systems. Full scale trafficking...

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...

The study showed that the actual power exponent values were between 0.02 to 7.16 and, for exponent values that were significantly different to 4, an initial pavement design life of 20 years would no longer minimize whole life cost. The consequences of this finding are far-reaching...
