Avani Chopra Assistant Professor of Chandigarh University Gharuan Mohali (Civil Department) 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. Key words: Epoxy resin, marshal test, softening point, penetration value, Asphalt. Cite this Article: Sumesh Sharma and Er.

The one of tshe main reason of quick deterioration of the pavement in condition of adverse climatic factor and heavy traffic loads is bitumen properties. From all the materials of road construction bitumen is more sensory to adverse climatic factor due to its thermoplastic properties bitumen is softened at high temperatures (summers) and it becomes brittle at low temperatures (winters) which leads to the formation deformation in pavement. Such as (Ruts, cracks, potholes and pits on the pavement) the most efficacious way to increase the properties of bitumen is the addition of
