The addition of Evonik products to the bituminous binders used in road construction does not only enhance the performance of road surfaces, it also makes construction work easier and safer.
APAOs from the VESTOPLAST® product range improve the low temperature flexibility, whereas VESTOWAX® Fischer-Tropsch hard paraffins decrease the viscosity of the binder and therefore allow processing at lower temperatures, resulting in energy savings and reduction of emissions. In addition to this, VESTOPLAST® as well as VESTOWAX® increases the deformation resistance at elevated temperatures.
Road marking compounds
The admixture of small amounts of VESTOPLAST® to hydrocarbon resin based road marking compounds can avoid the crack initiation during utilization. VESTOWAX® Fischer-Tropsch hard paraffins reduce the dirt pick as well as secure faster setting and therefore diminish the abrasion of road marking compounds right after application onto the road.
