Thermally Stable Adhesion Promoter for Hot and Warm Mix Asphalt
Thermally stable adhesion agent based on fatty acid maleates. Applied in road construction for improvement of adhesion of oil bitumen to the aggregates consisting both of acid and basic rocks, keeps enhanced adhesion properties of hot oil bitumens for up to 5 days.
DAD-M is homogeneous brown viscous-flow liquid recommended for manual and automatic adding 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 1 year after manufacturing.
DAD-M 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-M in specified amount
- Stirring until homogeneous mix is obtained
