Prediction of Load Associated Damage in Asphalt Layer

Prediction of Load Associated Damage in Asphalt Layer Ullidtz, Per - p Primary Author mixed material bibliography England Federal Highway Administration 1994 en English 1291-1308;p Proseedings ; The 4 th International Conference On the "Bearing Capacity Of Roads And Airfields" Volume 2 The first step in structural evaluation of pavements (when using the analytical-empirical approach) is the determination of layer thicknesses, moduli, and types of materials. Based on this the structural performance is normally predicted by calculating the number of loads to cause a certain amount and severity of cracking. Most procedures do not predict the changes in the structural condition, i.e. in the layer moduli. This paper presents two methods of calculating the damage, one based on the actual stress, i.e. the stress in the intact part of the cross sectional area, and another based on the peak internal energy. With both methods the changes in moduli and the fatigue life may be calculated for either controlled stress or controlled strain testing.
