ASI Solutions Ltd

Airfield Runway Preservation and Asphalt Maintenance

ASI Solutions Ltd is a developer and provider of innovative and sustainable solutions for the preservation of asphalt and other bituminous bound surfaces.

The company was formed in 1997 in the UK and, from its beginnings as a domestic operator, has expanded to become an international player in the asphalt infrastructure market. In recent years the company has developed a strong network of own sales force, distributors and partners that spans a substantial part of the industrial world. ASI’s sales focus is primarily upon countries with strategic commitment to the investment in and maintenance of extensive road and air transport infrastructure.

Airport infrastructure works are a core part of our business and our teams are experienced in providing the engineering skills and technologies necessary to deliver sustainable asset management solutions. To date ASI has successfully completed projects on the world’s major civil and military airfields such as Sydney, Heathrow, Birmingham, Manchester, Brize Norton, RAF Marham, Lisbon, Keflavik, Phnom Penh, Siem Reap, Antigua, Montego Bay, Rota and Airbus.

Working closely with airport operators, owners and carriers, we understand the need for maximum safety and security within ‘live’ environments.

Strict working operations rely on absolute performance; on-time delivery, quality and contingency. Downtime is not an option. We understand the commitment required to keep works on plan and flight schedules free from disruption.

Delayed flights cost huge sums of money, so airport runways need to operate at optimal capacity at all times. Runway maintenance needs to be undertaken fast as a minute’s delay to a take-off time can run into massive extra costs for the airline and the airport. But safety is also paramount, doubling the pressure on contractors to get things absolutely right in the minimum timespan.

Company Profile

  • About RHiNOPHALT®

    RHiNOPHALT® is a unique preventative maintenance treatment for asphalt which protects asphalt from weathering, oxidation and traffic wear. It addresses the major challenge of how to preserve and extend the life of expensive asphalt infrastructure such as airport runways and taxiways, road network, automotive tracks and car parks. It has proven to be a very reliable, effective and innovative method of preserving asphalt infrastructure all over the globe, offering substantial operational, environmental benefits and long-term cost savings to all parties involved.

    RHiNOPHALT® is fundamentally different to other surface treatment products. It penetrates the existing surfacing course and seals in essential oils and resins, whilst at the same time improving the binding and waterproofing properties of the existing surface. As a result, the treated surface will become more resistant to abrasion, stone loss, water ingress and the severe ageing effects of extreme temperatures.

    RHiNOPHALT® is best utilised as part of a planned preventative maintenance tool in asset management, extending the operational life of the asphalt pavement and removing the large costs of resurfacing and repair works. But, also it is used extensively to extend the life of older pavements and allow for planned replacement funding to be arranged, or to arrest aggregate loss.

    As the bitumen ages, the asphalt loses its flexibility and becomes more brittle leading to an increased prospect of ravelling and pot-hole formation. This surface aggregate loss is a major safety concern to all airport operators as it poses a severe FOD risk.

    RHiNOPHALT® provides almost silent working. It can be applied day or night to significantly reduce any issues with lane availability or traffic disruption, and will generally cure within 30 minutes to 2 hours, dependent upon climatic conditions. Areas ranging from 10,000m2 to 60,000m2 can be applied by tanker in a single shift and the largest airfield contract we have done to date saw 270,000m2 preserved at Keflavik from 7th to 11th July 2009. The whole process of preservation, grip recovery and re-lining can be carried out in shifts of as little as 5 hours. Productivity is much improved over the conventional surfacing treatments.


      • No change to the surface characteristics. Texture is maintained, grip restored
      • Strengthened surface aggregate matrix minimising FOD risk
      • Improved waterproofing and protection against weathering
      • Extend the life of the existing surface and delay the cost of major refurbishment
      • Lower reactive maintenance requirements, higher efficiency in air traffic
      • Less down time of runways, increased revenue
