Adhesion Promoter for Hot and Warm Mix Asphalt — amphoteric type
Amhoteric surfactant applied in road construction for enhancement of adhesion of oil asphalt to aggregates made both of acid and basic rocks. There are three types of DAD-1 (A, C, D) with different commodity form for convenient application in different customer’s technological conditions and with similar chemical effect on bitumen.
DAD-1 Grade «А» – is a homogeneous brown viscous-flow liquid recommended for manual or semi-automatic adding into a bitumen binder in an asphalt plant.
DAD-1 Grade «С» – is a homogeneous brown liquid recommended for automated injection into a bitumen binder in an asphalt plant by means of high-precision dosing equipment.
DAD-1 Brand «D» – fluid brown liquid, recommended for both manual and automated injection into the bitumen binder in the asphalt plant with high-precision dosing equipment.
Main Advantages[spacer] [service title=”Universal (Amphoteric Surfactant) ” icon=”icon: hubzilla” icon_color=”#102956″ class=”sk-service”]DAD-1 adhesion agent contains anionic and cationic functional group, which allows to improve bitumen adhesion to not only acid rock, but also basic rock and neutral rock and to use a universal approach to selection of the aggregate required for production of asphalt mixes. This is compares DAD-1 agent favourably with common amine-based agents composed of cationic functional groups only.[/service] [service title=”Environmentally-Friendly” icon=”icon: leaf” icon_color=”#102956″ class=”sk-service”]DAD-1 adhesion agent is produced of absolutely safe and environmentally friendly raw materials. Most of alternative cationic or acid agents are toxic and less safe for use.[/service] [service title=”Cost-Effective” icon=”icon: diamond” icon_color=”#102956″ class=”sk-service”]DAD-1 is very cheap, therefore, when it allows to save up to 20–30% of adhesion agents cost even despite the higher concentration of injection.[/service] [service title=”Adaptable” icon=”icon: cogs” icon_color=”#102956″ class=”sk-service”]The agent is available in different viscosity versions adapted for manual and automated addition by dosing equipment. Shipment in small-volume package for convenience of manual loading is possible. Relatively high concentration of injection of the preparation to bitumen allows to define minimal required dosing volume of the product with higher precision.[/service] [note note_color=”#e3ecff”][spoiler title=”Other our adhesion agents” class=”sk-spoiler” icon=”plus-circle”][siblings][/spoiler][/note]
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-1 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-1 in specified amount
- Stirring until homogeneous mix is obtained
