Dynamic Viscosity Analysis of Base Bitumen with the Addition of Rediset

Abstract:

This paper investigated the influence of Rediset on the properties of base bitumen. The warm mix bitumen binder were produced by mixing a standard 40/60 pen bitumen with Rediset at fixed two proportions. The dynamic viscosity behaviour of the samples have been determined using dynamic shear rheometer with a cone and a fixed plate with a diameter of 25mm. The thermal stability of the Rediset was characterized and the result indicate that the physicochemical properties of Rediest are stable bellow 150°C. The dynamic viscosity result shows that the addition of Rediset can affect the flow behavior of the bitumen. Rediset decreases the viscosity of the binders, especially at the range of 100°C~150°C. The contribution of Rediset to the change of viscosity became less with the temperature increasing from 100°C to 150°C.
