Asphalt preservation can double the surface life of roads, says ASI MD

Asphalt preservation treatment could double the asphalt road surface service life for half the cost compared to resurfacing, if two treatments are made in 10 years, according to Howard Robinson, Managing Director of ASI Solutions.

This is based on treating roads in a green to light amber condition, and in particular Stone Mastic Asphalt (SMA) and Thin Surface Course Systems (TSCS), which ideally should be treated two years before reactive maintenance is need to help prolong the life.

Dr Robinson was speaking at the first of series of CPD accredited webinars in association with the Local Roads Improvement Group (LCIG), taking place over the summer.

He said reactive maintenance was ‘inevitable’ sooner rather than later on these types of roads but preservation could delay more expensive intervention treatments. “More and more local authorities are using our RHINOPHALT treatment to help keep their roads in better condition for longer. As well as this, preservation helps with compliance including the Well-Managed Highway Infrastructure Code of Practice.”

As well as demand for reactive maintenance, fewer potholes and less claims, asphalt preservation helps with life-cycle planning and the Incentive Funding Band 3 objectives. It also provides ‘invisible working’ with up to 30,000m2 being treated per shift, per night. Breaking the deterioration cycle, its aesthetics are enhanced and visible to voters and more than 90% carbon savings can also be achieved compared to resurfacing.

RHiNOPHALT is a preventative maintenance treatment for all asphalt which preserves, protects and extends the life of the asphalt infrastructure and is proven to withstand all extreme weather conditions. Applied to the asphalt surface and penetrates through micro-cracks and interconnecting voids to form a hard seal, keeping water out and slowing the ageing process. RHiNOPHALT contains a natural asphalt, Gilsonite, which is a mineral antioxidant and is a key component in preventing asphalt deterioration caused by oxidation of the bitumen. Gilsonite resin
is much harder than bitumen – it is an antioxidant that reinforces, seals and
strengthens the surface course and slows down asphalt ageing.

“Treatment of RHINOPHALT does not prevent other treatments in the life cycle from being used it just keeps green and light amber roads in good condition for longer,” says Dr Robinson.

RHINOPHALT® is also a highly-engineered asphalt preservation system, meeting requirements of clause 950 in the Specification for Highway Works and carries a HAPAS certification and CE Mark.

RHINOPHALT has been applied to sites on the M40, A6, A50 and A421 as well as on many other local roads including in the areas of Staffordshire, Blackpool and Leicestershire.
