Surface dressing
What is surface dressing?
Surface dressing is a way of protecting and improving roads. It involves spraying hot bitumen on the road and covering it with stone chippings. Vehicles help press the chippings into the surface.
It is
- cost-effective - much cheaper than full resurfacing
- quick - reduces delays for traffic
- durable - can extend the life of a road by up to 10 years
When does it happen?
Work is usually done between May and July when the weather is warm and dry. Wet or very hot conditions can stop the process from working properly.
Surface dressing vs resurfacing
- Surface dressing: prevents damage on roads that are still in good condition
- Resurfacing: replaces damaged layers when a road is badly worn
Why do we do it?
- Makes roads safer by improving grip
- Stops water getting into the road surface
- Extends road life
How is it done?
- Hot bitumen sprayed on the road
- Stone chippings spread and rolled in
- Loose chippings swept away over the next few weeks
- Road markings replaced after the final sweep
Why is there a 20mph speed limit?
To
- reduce skidding on loose chippings
- prevent damage to vehicles
- help chippings settle into the surface
How will I know if my road is affected?
- You'll get a leaflet before work starts
- Signs will be put up with dates
- Roads may close for a short time - emergency access is always maintained

The case for surface dressing
Road Emulsion Association (REA) and Road Surface Treatment Association (RSTA) have joined forces to explain why surface dressing is the solution to reducing potholes.
