Rutting has been one of the major problems in asphalt pavement engineering since it deteriorates not only performance but also serviceability of the pavement. Proper evaluation oh rut depth can be an essential factor for economic management of asphalt pavement. This study describes a prediction method of rut depth in asphalt pavement which consists of pavement materials characterization, struct…

Backcalculation of FWD data often results in unrealistic layer moduli. The modulus of the subgrade may be two to three times the expected value, and the modulus of an intermediate granular material may be lower than the subgrade modulus. If stresses or strains measured in the pavement are compared with theoretical values, the agreement is often poor. All theoretical models for calculating pa…
