The chemical division of Colas
Chemoran prides itself on the development, manufacture and supply of a range of emulsifiers and bitumen additives for our partners in the Colas group worldwide. Our products enable Colas to be a world leader in the promotion and manufacture of environmentally-friendly pavement works and preservation techniques.
Bitumen emulsions are a low-carbon alternative to hot binders and are used world-wide by Colas subsidiaries for surface dressing (chip-seal), cold-mix asphalt, in place pavement recycling and cold-asphalt micro-surfacing techniques.
Our bitumen additive called CWM™ enables the production of warm-mix asphalt and our adhesion agents extend the life of hot-mix asphalt by improving the degree of adhesion between the bitumen and the aggregate.
