Surface Extension Treatments are paving the way for a more cost effective and sustainable future…

Innovation is driving change in the highway maintenance sector. More local authorities are changing their approach to asset management programmes to include more preventative, early intervention treatments that are proving cost effective, innovative and sustainable alternatives that work effectively alongside the more traditional treatments.

This in part, is being driven by the need to prioritise funding more effectively and reduce carbon in the maintenance cycle, as well as a move towards treatment intervention predictions to understand in greater detail the early deterioration of the road surface so measures can be taken before it is too late.

Currently though, the highways management system still directs spend in red areas not for surface extension treatments on green roads. Some survey systems often ignore the green roads and report back on the amber and red conditions because that is what the algorithms in their systems are designed to do. But thankfully this is starting to change.

One surface extension treatment that helps solve these challenges is Reclamite. Did you know that by applying Reclamite in the first five years of the life of the surface, the return will simply dwarf the investment involved?

If, for example the local authority in this example reallocated £1 million from the ‘red roads’ budget and applied Reclamite – it would be able to treat approximately 50km of its local road network. So, if you have a road network with a length of 700km, when the process is repeated over the next 10 years you would have been able to treat 500km. The local authority would then still have 500km in green condition.

Incorporating surface extension treatments into asset management planning will extend the life of your network and reduce the need for disruptive reactive maintenance. It can also enhance the benefits gained from improved public perception and fewer insurance claims.
Reclamite, which is a penetrative bitumen rejuvenator which is BBA/Hapas approved and has been used in the USA for over 50 years and in mainland Europe. It was first used in the UK in 2007.

It can be applied before defects become evident. This enables the bitumen to be rejuvenated through the full depth of the wearing course. The micro cracks are sealed preventing them developing into visible cracks and then into potholes and other defects. At the same time, the surface will be resistant to the ingress of water.

What about the parts of the network that you would like to surface dress but have been unable to due to noise threshold or traffic behaviour? Until now you may have left the asset to deteriorate with patching and multiple repairs required before replacement is the only option – ‘sweating the asset’.

Using SET solutions brings the following additional benefits at installation:

Environmental

  • Reducing environmental impact by 88%.
  • No quarried aggregate.
  • No landfill generated.
  • Low noise compared to traditional repairs.

Financial

  • Whole life cost reduction of up to 40%

Operational

  • Efficient installation minimising disruption,
  • minimising traffic management costs.
  • Keeping the traffic moving.

Safety

  • Primarily mechanical process – minimal
  • human interaction.

One early adopter of Reclamite is Norfolk County Council, which has considered carefully its whole life costings and when viewed against traditional treatments, Reclamite is delivering best value. As a result, the council has included the use of Reclamite in its Transport Asset Management Plan.

Roadtechs supports all these processes with a site survey to understand it detail what our customers require.
