Drivers are reminded to drive at 20mph or less through areas being treated with surface dressing. We advise this speed to help keep our workers safe and to minimise the hazard of flying chippings picked up by tyres.
Residents whose roads are being treated will be notified by letter to help ensure roads are cleared of vehicles to allow the work to be carried out as quickly as possible.
After the initial surface dressing operation and first vacuum-sweep of loose chippings, the roads are swept at seven days and six-week intervals to ensure safety of all road users. Typically 10% of chippings are swept up over the six-week period and recycled for more surface dressing work on other less busy rural roads to ensure no materials are wasted.
This process involves covering the carriageway with a minimum thickness of 40mm of dense hot laid surfacing material. This is carried out to replace a failed surface that is not suitable for Surface Dressing. Resurfacing restores the ride quality and skidding resistance and can reduce surface noise.
