The objective of this study was the evaluation of high-modulus asphalt mixtures (HMAM). Two types of hard-penetration bitumen (HPB) and conventional bitumen were used to fabricate Enrobés à Module Elevé Class 2 (EME2) and Grave Bitumen Class 5 (GB5)) and control mixtures, respectively. In this study, complex modulus, fatigue, dynamic creep and moisture sensitivity tests and also, Witczak and Zhou models were used to evaluate the performance of the prepared mixtures. Results showed that hard-penetration bitumen (HPB) improved the performance of asphalt mixtures compared to conventional bitumen.
