Synthesis of succinimide based novel additives for viscosity reduction of bituminous binder
Graphical abstract Display Omitted
Highlights Three bitumen viscosity reducers DDSA-TETA, DDSA-TEPA and DDSA-PEHA developed. DDSA-TEPA affects constitutive properties of modified bitumen most. Increasing DDSA-TEPA concentration decreases kinematic viscosity & complex modulus. Penetration increases, softening point decreases but ductility not deteriorated.
Abstract Three novel succinimide based additives DDSA-TETA, DDSA-TEPA and DDSA-PEHA were synthesized by a simple refluxing reaction between dodecenylsuccinic anhydride (DDSA) with triethylenetetramine (TETA), tetraethylenepentamine (TEPA) and pentaethylenehexamine (PEHA) respectively in toluene. All were characterized using elemental analysis (CHN), infrared (IR) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy. The compounds were then evaluated as additive in hard base bitumen in order to reduce the viscosity and increase the penetration. Comparatively DDSA-TEPA was found to be most effective in reducing the viscosity and improving the penetration property. It also shows the concentration effect without much affecting the other important physical parameters like softening point and ductility.
