Comparison of SBS, Crumbled Rubber and Zycotherm on VG-20 Grade Bitumen

This paper presents the comparison between three modifiers used in bitumen. The commonly used SBS and Crumbled Rubber has been compared against Zycotherm, which is a new generation silane additive. The paper presents a comparison between the modifications in penetration and softening point values of modified bitumen. The complex modulus variations obtained from DSR testing were also compared. The prices of the modifier used, per kilogram of bitumen has also been assessed. Citation: Nigil M, Vimal Jyothi Engineering College.
