The results obtained from ∇RG analysis clearly indicate that LY 450139 G*sin (δ) of warm binders decreases when Rediset® is added to the asphalt binders, while Sasobit® increases ∇RG, irrespective of the asphalt binder type. Consequently, Rediset® is a more desirable WMA additive compared to Sasobit®. The use of Rediset®-modified PG 76 is more desirable when intermediate temperature cracking needs to be considered.
