Heat stable Adhesion Promoter for Hot mix asphalt
Thermally stable adhesion agent based on polyphosphoric acid ethers. Applied in road construction for improvement of adhesion of oil bitumen to aggregates consisting of both acid and basic rocks, keeps enhanced adhesion properties of hot oil bitumens for 7 to 10 days.
Liquid of light-yellow to light-brown colour, recommended for manual or automated adding to bitumen binder at an asphalt plant.
Package and Storage
The preparation is supplied in 216l plastic barrels or 1m³ polymer containers.
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-KT 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-KT in specified amount
- Stirring until homogeneous mix is obtained
