Asphalt preservatives dramatically extend the lifespan of highways
The highways industry is faced with a unique challenge – The โRoadโ, with its depreciating finite life, cannot economically be renewed in line with traditional life cycle activities.
There are 31,000 potholes awaiting repair in the UK that is estimated could take 11 years to clear, while 1 in 7 drivers have claimed their car was damaged as a result of pavement defects, with more than ยฃ20 million paid out annually in third party claims.
Road works, both planned and unplanned are estimated to cost the UK economy more than ยฃ4.3 billion – is this sustainable? ASI Solutions response, and that of an increasing group of asset managers is that – it is not. Lobbying Government for more funds is one way forward, but unlikely to be successful due to budget constraints and spending cuts.
But there is another way – Using an asphalt preservative based Highway Asset Management methodology would have a dramatic effect on the long-term deterioration and sustainability of road surfaces, reducing wear and driving down costs.
RHiNOPHALTยฎ from ASI Solutions is the perfect example of a low cost, cold applied, chemically engineered preservative applied to the top surface of a โRoadโ, forming a membrane on, and uniquely, within the bituminous surface. Ideally, applied 1-2 years after surfacing has been laid and maintained as part of a 5-7 year cyclical regime of application and re-application with optimum results being delivered by targeting โRoadsโ with an IRI Condition Index of โVery Goodโ or โGoodโ to radically slow deterioration of the surface.
Preservatives have been used to treat assets like wooden buildings, fences, and even cars with surface preservative applications for many years, so ASI Solutions knew the technology works and developed their RHiNOPHALTยฎ preservative solution for bituminous surfaces to deliver economic and environmental savings by increasing the productive life of this โfiniteโ asset.
Typically RHiNOPHALTยฎ will save at least one resurfacing over a 20-year period and one of ASIโs largest motorway concession customers is confident of achieving whole life savings of close to 40% and will minimise the amount of โunplanned interventionsโ that would normally be expected to be carried out, which are estimated to be reduced by 66%.
