DESIGN CONSIDERATION FOR ASPHALT PAVEMENTS

This report describes some research which has been completed to permit estimation of the accumulation of permanent deformation from repeated traffic loading in asphalt-bound layers resting directly on subgrade. Constitutive relationships which attempt to define the distortion characteristics of a fine-grained soil as a function of water content, dry density, stress state, and number of stress repetitions are presented. In addition such relationships for asphalt concrete as a function of time, loading, temperature, and stress state are developed. The data for the asphalt concrete have been incorporated in analysis procedures using both layered elastic and viscoelastic theory to represent pavement response to load to illustrate a preliminary framework by means of which rutting in the asphalt bound layer can be estimated. /FHWA/
