Depending on the bitumen and aggregate natures used, it may be necessary to improve the coating and bonding between the bitumen and aggregate interface. A consquence of better bonding has been proven to give much better water resistance to the asphalt and therefore longer life pavements.

Nayler Chemicals has a range of adhesion agents. Included within our range are heat stable products designed to be added to the bitumen when stored for a period prior to mixing in the asphalt plant.  

Nayler Chemicals also offers the Arkema Cecabase products into this area.
