RHiNOPHALT® is a unique preventative maintenance treatment for asphalt which preserves, protects and extends the life of expensive asphalt infrastructure such as airport runways and taxiways.

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® can be applied day or night and will generally cure within 30 minutes to 2 hours, dependent upon climatic conditions. Areas ranging from 10,000m² to 30,000m² 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 7 to 11 July 2009.

The demand for air transport is high and air travel will most likely double by 2035, according to PC’s 2015 annual report on the state of the worldwide airline industry. The aviation industry is experiencing significant change as airport expansion plans rise to the top of government agendas to meet the growing demand from today’s business and tourist travellers.

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 of almost 2 million square metres on the world’s major civil and military airfields, such as Heathrow, Birmingham, Manchester, Brize Norton, Lisbon, Keflavik, Phnom Penh, Rota or Airbus.

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.

The whole process of preservation, grip recovery and re-lining can be carried out in shifts of as little as five hours. Productivity is much improved over the conventional surfacing treatments.

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 pavement and allow for planned replacement funding to be arranged, or to arrest aggregate less.

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.

Rather than adding a new layer of surface, RHiNOPHALT® penetrates into the top of the existing surface 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.
