Fundamental behaviour of unbound granular pavements subjected to various loading conditions and accelerated trafficking

Specific loading parameters (load magnitude and number of repetitions, tyre inflation pressure and basic tyre type) that influence the fundamental behaviour and performance of unbound granular pavement layers and subgrades were studied. Three flexible pavements were tested in sequence in the Canterbury Accelerated Pavement Testing Indoor Facility. Strain measuring technology suitable for instrumenting unbound granular and subgrade materials was developed and proven. The subgrade strain criteria for flexible pavement designs are conservative, and linear elastic theory is inappropriate for unbound granular pavements. Surface rutting after an initial trafficking period, combined with appropriate modelling, can be a reasonable predictor of pavement performance.
