Industry collaboration to improve concrete carriageways in Brighton

Project

Concrete pavement rehabilitation scheme with rj dance and power plane for Brighton & Hove City council

Background

Brighton & Hove City Council, like many other local authorities, still has miles of concrete carriageway that left alone will deteriorate slowly over decades. With the City Council’s push to being Carbon Neutral in 2030, the Highway Asset Maintenance Team decided it needed to become ‘Carbon Clever’.

Looking at the way they traditionally dealt with maintenance of their road network and where value engineering and the change of process can reduce the carbon footprint of a scheme, without impacting on the long-term resilience of the solution, has become a key part of this thinking.

County Oak Avenue was a case in point, a concrete road that had been overlaid with a thin Microasphalt (there are many roads like this in the City) – aesthetically it was looking tired and needed an effective maintenance solution before more long-term issues started to arise.

Solution

Working in partnership with their Term Maintenance contractor, RJ Dance, Brighton & Hove City Council engaged with Roadtechs and Power Plane to deliver concrete pavement rehabilitation works at County Oak Avenue, Brighton.

As an industry, we continue to develop techniques and procedures that will result in cost effective and longer-lasting pavement rehabilitation. Concrete pavements rehabilitation with Fine Milling and Techcrete Repairs is one such technique – ensuring excellent adhesion and extension that maintains high tensile strength and compressive resistance.

As an industry, we continue to develop techniques and procedures that will result in cost effective and longer-lasting pavement rehabilitation. Concrete pavements rehabilitation with Fine Milling and Techcrete Repairs is one such technique – ensuring excellent adhesion and extension that maintains high tensile strength and compressive resistance.

Roadtech’s concrete pavements rehabilitation solution and repair product, Techcrete, is literally flexible and is Highways England and TRL approved and recommended. This solution enables in-situ localised repairs, is versatile in the types of repair possible and is rapid setting so suitable for short duration closures. The high skid resistance restores ride quality and seals the surface from further water ingress.

The work on this scheme included:

  • Removing the thin Microasphalt surface, using a fine milling machine
  • Repairing all the joints using Roadtechs’ proprietary product – Techcrete
  • Fixing failed gullies with a five-year warranty
  • Replacing the failed speed humps and dealing with the ponding issues around them – the flexible repair with an imprint (block effect) is more resilient and will outlast traditional designs

During the works, near a local primary school, we gained an audience with some of the children intrigued as to what we were doing and the vehicles we were using. Our site supervisor took some time to explain the process to the children and their parents which was very well received (and will hopefully encourage our highway engineers of the future!).

 

“The children really enjoyed watching this process. Can I just say how amazing the workers were. They took the time out to explain to my son and friends what was happening and all the names of the vehicles and what they do. My son is obsessed with construction vehicles so the fact they took this time was so lovely.”

Local Resident

Outcome

The rapid installation process ensured the works were carried out in a timely manner with minimal disruption to local residents and traffic.

The concrete pavement rehabilitation process provides:

  • Restored and improved texture depth value
  • Noise reduction (10dmb quieter than asphalt) and an improved ride quality
  • A proven durability and reliability – providing a more resilient road surface and minimising ongoing maintenance issues
  • Less disruption as it can be driven on immediately
  • A more aesthetically pleasing road network
  • Reduced Carbon footprint – no bitumen products or deliveries

“Roadtechs were professional and efficient throughout the whole process from design, survey and through to the delivery stages. We found them to be knowledgeable and they were able to provide everything for the works to be completed.

This method of repair takes away the issue of constant complaints about potholes and bitumen based thin surface treatments delaminating from the concrete pavement.
The difference can clearly be seen in the before and after photos and the residents and Councillors are pleased with their “new” road.

This was achieved through collaboration at every stage and has resulted in a reduction in the carbon footprint compared to other more expensive traditional options – not only during construction but in the Whole Lifecycle as ongoing maintenance has been designed out.

We are planning more works with Roadtechs and look forward to collaborating with them again.”
