Highways England’s contractors A-one+ is using new machines to resurface a main road in Northumberland, England, which are ten times more efficient than traditional methods, reports Construction Enquirer website.
The kit allows the underlying layers of the road to be recycled, taking up the old surface material, combining it with new material within the body of the machine then laying it immediately on the road behind.
Up to 1,000 tonnes per hour can be resurfaced compared to an average of 100 tonnes per hour using conventional methods.
As well as being able to resurface larger areas, there is also a 75% reduction in the amount of quarried stone used on the job, a 66% reduction in the amount of waste taken to landfill and there are 70% fewer lorry trips to and from site.
Steve Bishop, project manager, Highways England said: “There are lots of benefits to using this new way of working.
“It means we can resurface larger areas of road, there are fewer construction vehicle trips and the road surface is designed to last for at least 10 years, meaning that we shouldn’t need to go back to carry out further repairs any time soon meaning less disruption for drivers.
“This is the first machine of its type in the UK but the process is already successfully used in the USA, France and China.
The project is expected to take 3 weeks and work will be carried out during the day by subcontractor Lane Rental Services.
