PEDRO, PErmanent Deformation of asphalt concrete layer for ROads

PEDRO is a viscoelastic uni-layer model that can be used to predict rutting components (post-compaction and shear rutting) in bituminous pavement layers that are subjected to traffic loading.

Vehicle characteristics, such as axle load configuration, speed, tyre-pavement interaction, and influence of lateral position, are taken into consideration to estimate rut development as a function of pavement age.

The PEDRO model utilizes the viscosity of bituminous materials, hourly measured traffic and climate data, and the geometry of the pavement structure.
