Abstract: The objective of this study is to determine the effect of bitumen modification with varying percentage of ethylene vinyl acetate (EVA) for preparing the hot-mix asphalt containing various aggregates (marble, granite and quartzite) and compare the results with mixes prepared with neat viscosity grade 30. The selection of aggregates has been done based on their acidic and basic nature. The physical and mechanical properties of EVA-modified bitumen and neat bitumen aggregate mixes were evaluated. Moisture susceptibility tests and wheel tracking test were carried out on the samples. Brookfield viscometer and dynamic shear rheometer were used to determine the mixing and compacting temperatures of neat and modified bitumen. The results indicate that mixes prepared with aggregates that are basic in nature, i.e. with higher calciumcontent, show better bonding with both neat bitumen and EVA-modified bitumen compared with acidic aggregates, i.e. aggregates with higher silica content. ¬© 2014 Taylor & Francis.
