Abstract

Two eco-compatible bituminous materials were analyzed as surface layers in two different structures under varying conditions. The pavement performances were simulated using the CalME design software with parameters obtained from Repeated Simple Shear Test and 4 Point Bending tests. The primary purposes of this study are to demonstrate the value of the eco-compatible mixes with regard to their mechanical performances and to examine the relations between their fatigue and rutting performances and the pavement structures. It was verified that the suggested asphalt thickness should correspond to a reliable pavement foundation when surface layers may suffer of stiffness and/or rutting deterioration.
