Eco-friendly road resurfacing
Minimum disruption
Peacehaven, Brighton
Roadways was asked by Lewes District Council to price repairs at The Promenade in Peacehaven, Brighton. Initially project scope was limited to filling potholes with crushed stone in the badly compacted concrete road. Upon Roadways' advice, a better plan was developed which cost less, caused minimum disruption and improved the road for residents and road users.
Innovation
Less disruption, saving money
Longer lasting than traditional methods
CHALLENGE
The road is beside a cliff, so crushed and compacted stone would wash away in very quickly, and potholes would soon appear again.
Roadways came up with an alternative design, suggesting a long-lasting solution, with better value for money. Roadways’ HBM, with recycled materials, could be installed for the same price.
Lewes District Council did not hesitate to apply a strategic approach to this road problem and agreed to Roadways’ suggestions. The council decided to address the road’s underlying problems – lessening the need for future maintenance.
This road is now expected to last ten or more years – instead of just a few rainstorms in this exposed location.
THE RESULTS
- Innovative solution
- Eco-friendly method
- Less disruption to local residents and road users
- Emissions cut from road use
- Longer-lasting road surface
- Cost savings for taxpayers
The road will last ten years or longer, and will only need to be resurfaced when the natural life cycle of the surface dressing comes to its end.
PROJECT SCOPE
Roadways carried out a range of works:
- Innovative Point Cloud LIDAR scanning was performed to define the correct road levels.
- Road foundations were strengthened using environmentally-friendlier recycled road materials: a 150mm layer of HBM (hydraulic bound material) or roller compacted concrete.
- The road was narrowed to 3m to slow traffic.
- Excavated materials were used to form bunds to stop parking and deter people from driving too close to the cliff edge
- Water diverters and speed humps were constructed
- The project was surface dressed and completed in September 2020
Over 20 highly skilled operatives, supervisors and engineers were involved in the project.
