Shakedown analysis of road pavement performance

摘要

Shakedown behaviour of road pavements was investigated in laboratory controlled conditionsusing the Sydney University Pavement Testing Facility. Wheel loads lower than the shakedown load generated lowpermanent deformations for a larger number of load cycles in comparison with high permanent deformationsfor a lower number of load cycles for wheel loads higher than the shakedown load. Computer software wasdeveloped to calculate the shakedown limit using elastic stress distributions calculated with Sydney University'sFLEA (Finite Layer Elastic Analysis) program.
