Abstract
The investigation of the pavement performance under dynamically increased wheel loads combines approaches about the modelling of axle assemblies, the simulation of the dynamic wheel loads due to longitudinal unevenness as well as the estimation of the impact on the service life of pavements. The focus in this work is laid on the determination of distress and service life of rigid pavements under dynamic wheel loads using a recently introduced and for the purpose of this study adopted mechanistic-empirical design method for rigid pavements. The results show a good correlation between the assessed Weighted Longitudinal Profile (WLP) (as an indicator for longitudinal unevenness) and the theoretical service life of rigid pavements. Based on that correlation a rating scheme for longitudinal unevenness is introduced. It allows the classification of the unevennes of roads in a five-grade system depending on the WLP and the definition of limiting values for the longitudinal unevenness.
