ASI Solutions Limited

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

What we do

RHiNOPHALT®, ASI’s best known product, is an asphalt preservative which is proven to extend the service life of asphalt assets such as roads, footways and car parks, as well as test tracks and airport runways and taxiways. Rhinophalt is a cold spray-applied sealer which penetrates into the asphalt surface and forms a very hard seal which protects against the damaging effects of water ingress, UV light and traffic wear. Ultimately Rhinophalt reduces the risk of surface failure and increases pavement life. Utilised as part of a planned maintenance program, asphalt should be treated with Rhinophalt 2 years before surface defects are expected; the treated surface is maintained in the same condition for longer with clients typically experiencing 50-100% extension of pavement life. This is good for Local Authorities, good for drivers as it means road are kept in good condition for longer and there is less congestion due to roadworks, and good for taxpayers.
