Viability Assessment and Cost-Effectiveness of Using High-Modulus Asphalt Concrete (HMAC) as Base Course in Asphalt Pavements in Louisiana

The main objective of this research study is to evaluate whether local virgin and recycled materials in Louisiana could be used to produce Enrobé à Module Élevé- (EME) mixtures so that it can used as a base course in asphalt pavements. To achieve this objective, high-modulus asphalt mixtures mimicking the European approach will be prepared using the Superpave specifications. These mixtures will include different asphalt binder grades, polymer contents, and reclaimed asphalt pavement (RAP) percentages. The dynamic modulus as well as the performance of these mixes against rutting, moisture damage, and fatigue cracking will be evaluated. The results of this study will provide solutions for fatigue and rutting failures in asphalt pavements in Region 6, hence, enhancing the durability and service life of the road infrastructure.
