Aggregate pre-coating approach using rubber- and silane-coupled thermoset polymer and emulsion for warm-mix asphalt mixtures

The surface strength of the synthesized epoxy was at least 2-fold greater than the general epoxy sample, as verified by the Dolly test. The chemically modified epoxy was used as a coating agent for aggregates and made possible to react with the water molecules in the emulsified asphalt binder. The bonding effect was verified by the boiling test, maintaining greater than 90% of the coated film.
