Adhesion Promoter for Hot and Warm Mix — cationic type
Surfactant based on polyamide-amines and imidazolines of fatty acids. Provides high degree of bitumen adhesion to different aggregates with high acidic properties. DAD-K improves and accelerates wetting and covering of the surfaces of mineral materials and thus increases adhesion of bitumen to filler.
Homogeneous dark-brown viscous-flow liquid recommended both for manual and automated injection into a bitumen binder in an asphalt plant.
Package and Storage
The preparation is supplied in metal barrels with volume of 216l or 52l and polymer containers with capacity of 1m3.
The preparation is stored in transport package or in hermetically sealed package. The preparation is stored in closed storage areas at distance of at least two metres from heating elements, at temperature from minus 35°C to 50°C, in open areas under sheds or in special heated tanks.
Guaranteed storage life is 2 years after manufacturing.
DAD-K may be added both into an operating reservoir at the stage of binder preparation and directly in the bitumen supply line of asphalt plant mixer.
The technology of production of bitumen modified by the agent includes:
- Heating of basic bitumen up to operating temperature
- Adding of DAD-K in specified amount
- Stirring until homogeneous mix is obtained
