COMPARATIVE STUDY OF CONVENTIONAL AND EPOXY MODIFIED BITUMINOUS MIX
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
The efficacious way to increase the life time of asphalt mix pavement subjected to traffic load is the modification of bitumen with the thermosetting polymers. In this study epoxy resin is used for the modification of bitumen. The epoxy resin added in different % in the bitumen mix (that’s 1, 2, 3, 3.25, 3.5, 3.75& 4) and the test result of modified and unmodified mix are compared by the marshal test. The properties of the mix evaluated by the marshal are stability, flow, air voids, volume of mineral aggregates & void filled with bitumen. The optimum content of epoxy resin to be added in the bitumen mix is 3.25% as per marshal test. The softening point and penetration test is conducted on the modified and unmodified bitumen and the test results of the modified bitumen are better as compared to unmodified bitumen.
