Frequently Asked Questions
What is Surface Dressing ?
This is a traditional tried and tested method that involves spreading a layer of stone chippings onto a thin layer of bitumen binder, which is sprayed onto the road first. This type of treatment is used on roads that are structurally sound but require a new surface to improve skid resistance. The treatment also helps prolong the life of the road by sealing any surface crack and preventing water ingress.
The process usually leaves surplus chippings on the road surface but these will normally be ‘run in’ by traffic movement or swept up during routine sweeping operations. The surface is usually free from any loose chippings within a few weeks but further sweeping will be arranged if required.
What is Patchwork ?
Patchwork involves cutting into the surface around the area of the pothole and removing the damaged surface. New material is then laid into the hole and compacted to repair the area of damage. This technique is used when there are localised areas of damage that do not require the entire road to be resurfaced.
Very often patching is carried out prior to Surface Dressing when there are areas of increased damage to the road surface that Surface Dressing cannot remedy.
What is Plane & Resurface (PRS) ?
PRS is used on roads that have severe irregularities and / or structural problems. The technique involves removing some or all of the existing surface and using a machine to lay new hot material on to the carriageway, which is then rolled to compact it and give a smooth running surface.
PRS results in improved skid resistance and a smoother ride for road users, and also means the road surface should require less maintenance in the future.
