Hundreds of tonnes of road surface from a stretch of motorway in Cumbria are to be ripped up, recycled and put back in.
More than 20 lorry loads of motorway surface will be taken off the M6 between the Killington Lake Services and junction 37.
The method is being used to preserve the aggregate stock and cut waste.
The work starts on Monday and will involve the closure of the northbound carriageway with a contraflow system southbound from Sunday night.
Low-noise materials
Around 470 tonnes of road material will be taken off the motorway and taken to a specially prepared recycling site to be regraded and remixed before being brought back.
Highways Agency project manager Phil Davies said: "Recycling some of the existing road surface reduces waste and preserves the nation's stock of aggregate and raw materials.
"The new road surface will use low-noise materials to improve carriageway condition and safety."
The work is due to go on until 7 November and there will be a 50mph speed limit.
