Effect of fly-ash based geopolymer coated aggregate on bituminous mixtures

Abstract

The research presented in the paper is conducted to evaluate properties of fly ashbased geopolymer coated aggregates and their effect on characteristics of bituminous mixtures. The investigation included aggregate testing, scanning electron microscope (SEM) analysis of fly ash and fly ash-based geopolymer, Marshall mix design, indirect tension test, dynamic shear rheometer (DSR) test for rheology, and repeated load test on bituminous mixtures with fly ash-based geopolymer coated aggregates.
