Adhesion Promoters
Added to bituminous mixtures, they create a very strong chemical bond between aggregates and bitumen, which is indissoluble and resistant to traffic and especially to the water damage extending the service life of road pavements.. New generation additives: biodegradable, odourless, non-toxic and non-hazardous to humans and the environment.
ADHEBIT LA-1245
Liquid additive, offering the best value for money. It guarantees both active and passive adhesion with all types of aggregates, both siliceous and calcareous. It establishes a very strong chemical bond between aggregates and bitumen, indissoluble and resistant to traffic and the disintegrating action of water, prolonging the service life of road pavements. Odourless, non-hazardous and non-toxic chemical.
ADHEBIT LA-1247
Liquid, high-performance additive. Extends the service life of road pavements. Provides chemical adhesion between aggregates and bitumen resistant to the disintegrating action of water. Improves workability and facilitates compaction even at lower temperatures than those traditionally used. Odourless, non-hazardous and non-toxic chemical.
Unique Antistripping Agents / Adhesion promoters: biodegradable, environmentally friendly, odourless and non-hazardous to human health and the environment; they perform far better than traditional amine-based Antistripping Agents: they make bitumens adhere to any type of inert material by creating a chemical bond that resists the destructive forces of water
Features & Benefits
Promotes Aggregates/Bitumen Adhesion
-
Reduces bitumen/aggregate surface tension by promoting bitumen adhesion to any type of aggregate even in the presence of moisture (Active Adhesion).
-
Creates a chemical bond between bitumen and aggregates, forming a film resistant to traffic and to the disruptive action of water (Passive Adhesion or Stripping Resistance).
Improves Workability and Compaction
-
Significantly increases the workability of bituminous mixtures.
-
Facilitates compaction by achieving optimum density with fewer roller passes.
Extends Pavements Service Life
-
Establishes a bitumen/aggregate chemical bond that prevents degradation of the pavement by preventing surface crumbling, the formation of potholes and cracks.
-
Delays bitumen oxidation.
Sustainability and Environmental Impact
-
Increases the amount of Reclaimed Asphalt.
-
Prevents overheating of aggregates when adding Reclaimed Asphalt.
-
Reduces CO2 emissions and plant energy consumption.
-
Eliminates the risk of exposure to chemicals for paving and plant workers as it is odourless, biodegradable, non-toxic and non-hazardous to humans.
Safe and Easy To Use
-
Liquid and pumpable at low temperatures.
-
Low use dosage.
-
Performance is maintained after long storage in hot bitumen.
-
It does not emit odours in mixes, eliminating the problems of fumes and bad smells typical of “amine” additives that can be problematic from an environmental and health and safety perspective.
-
It can be handled and stored without special precautions; it is not regulated as a dangerous good for transport.
