DESCRIPTION:
RoadChem™ 510® is a cationic emulsifier for the manufacture of asphalt emulsions for high performance dense graded cold mixes.
RoadChem™ 510® is designed to have a wide range of compatibility with aggregates and is particularly suited to aggregates that have adhesion problems. The emulsifier provides extended mixing times to ensure coating and adhesion. This allows mixing with soils, graded or ungraded aggregates.
RoadChem™ 510® may be used with a range of different polymer modification including Neoprene, SBP, EVA, EMA and SBS.
RoadChem™ 510® emulsions pass the cement mixing test and are very stable on dilution.

BENEFITS:

• Stability
• Easy to handle and transport
• Wide range of compatibility with aggregates
• Extended mixing times to ensure coating and adhesion

PHYSICAL PROPERTIES:
Appearance: Brown Liquid - amine odour.
Flash point (Closed Cup): > 100C
Pour point (C): 10C
Boiling point (C): 101C
Specific gravity: 25C 1.08-1.09 kg/It
Viscosity. cps 25C: 1000
pH of 15% solution in water: 10.4-10.6
Solids: 60%
Storage life: Min 12 months in drums or bulk. (20-50C in covered area in sealed drums).

APPLICATION:
Emulsion Manufacture: RoadChem™ 510® should be kept at 30C or higher prior to use for pumping. It should not be stored at above 60C.
RoadChem™ 510® can be easily neutralized with hydrochloric acid (concentrated). It is good practice to acidify the water before addition of RoadChem™ 510.

TYPICAL FORMULATION:
All formulations should be tested in the laboratory before use.

Cold Mix Emulsion
Asphalt 62-65%
Soap (based on total emulsion by weight)
RoadChem™ 509 1.0-2.5%
Concentrated BCI (pure): to pH 2.5-3.5

NOTES:
Note that RoadChem™ 510® should be added to warm water that has already had the acid added to it. The emulsifier buffers the solution so mix for at least 20 minutes before testing pH.
Note also that slurry and microsurfacing emulsions must be designed relatively to the mixture. That is a full ISSA mixture design must be done to verify performance.
