Experimental investigation on the application of the aggregate of gneiss-based migmatite in asphalt mixture of AC-13

In this research, the aggregate of acid migmatite and its application in the asphalt mixture were evaluated experimentally. In order to study the performance of asphalt mixture with the aggregate of acid migmatite, four different compositions of mixtures were designed by Marshall method. Six test me...
