Fine bitumen droplets dispersed in water with an emulsifier. Charge, setting behaviour and aggregate compatibility determine the right product. Emulsion and recovered-binder tests must be considered separately. Tack coats, surface treatments and cold mixes can call for different emulsion grades even on the same project. Share the intended treatment, aggregate information and specified setting class, together with the required tests and storage arrangements.
Reference limits from the SRNT catalogue, not measured batch results or a COA. Availability, the applicable standard edition and contractual limits are confirmed for each enquiry.

Emulsion tests and recovered-binder tests are separate. Use the recovery method and conditions shown; confirm the required specification edition and application-specific tests with your enquiry.
Grade selection also depends on the aggregate and intended treatment. Packaging, handling conditions, storage
period and final specifications are confirmed for each enquiry.
