DESCRIPTION:
RoadChem™309® is a specially engineered emulsifier used in the manufacture of high performance microsurfacing emulsions and quick set slurry emulsions. It improves the mix characteristics with a range of additives allowing lower emulsifier and water levels, even for difficult aggregates. RoadChem™309® systems are rapid curing and setting with the additional advantage of also being quick to traffic. RoadChem™309® is proven to give excellent mix set and cure characteristics on a very wide range of aggregate chemistry. RoadChem™309® is compatible with most Russian, Asian and Arabian crude based bitumen. Mix designs should always be carried out with any aggregate/bitumen system to ensure optimal performance.
