Since 1997, ASI has been supplying Local Authorities with innovative solutions to extend the service life of asphalt.

What we do

With over 170 years of combined experience in the asphalt and bitumen industry, our experienced team work closely with Local Authorities from the moment our products are introduced through to the successful completion of projects.

ASI is best known for RHiNOPHALT®, the original penetrative asphalt preservative.  HAPAS approved and CE marked, RHiNOPHALT® penetrates into the asphalt to form a hard seal, protecting against the ingress of water, and the damaging effects of weathering and traffic; preserving your asphalt surface for longer and delaying the need for expensive resurfacing

The RHiNOPHALT® preservation methodology also delivers enhanced sustainability when compared with alternatives. This is achieved through:

Significantly lower requirement for raw materials
Far fewer vehicle movements for maintenance and repair
Reduction or elimination of waste material disposal
Lower associated energy usage

It has been independently proven that RHiNOPHALT® delivers up to a 94% reduction in carbon footprint, when compared to conventional maintenance methods.
