The properties of cuplump-modified bitumen with was

TextPublication details: Journal of Rubber Research, 25(4): 367-373. 2022Subject(s): Online resources: Summary: This study focussed on investigation of fundamental properties of cuplump-modified bitumen (CMB) modified with an additive Ethylene Bis Stearamide (EBS) wax. EBS is a non-polar long fatty acid bis-amide with two central amide groups. The properties evaluated included conventional and rheological properties of CMB. The properties were tested using Viscometer, penetrometer, Ring and Ball softening tester and dynamic shear rheometer (DSR). Results indicated that viscosity of bitumen increases with the EBS addition. Greater temperature rutting resistance, softening point, stiffness and complex modulus were observed with EBS addition compared to the unmodified one.
