Road surface dressing works

One of the ways we maintain our roads is by surface dressing. This treatment seals the surface of the road to prevent water damage, improves surface texture and prolongs the life of the road. It is a quick, efficient and cost effective method of road maintenance, usually undertaken between April and August.

Notification of surface dressing works

When we plan to carry out surface dressing works we will put up notices along the road to let residents when we expect to start work.

When work is due to start vehicles should not be parked on the road or footway.

When the work gets underway traffic control measures will be in place to ensure everyone's safety.

2020 road surface dressing works

  • Park Lane, Whitefield - From Higher Lane to Hillingdon Road.
  • Radcliffe Moor Road, Radcliffe - From Bury New Road to Sunningdale Avenue.

The process

The surface dressing process is very weather dependent. The treatment cannot be applied to wet or cold roads or during high air humidity levels or very high road temperatures.

The step-by-step process is as follows:

  1. The road is swept and cleared in preparation.
  2. Bitumen is spread across the full width of the road.
  3. Chippings are spread on the road - these are embedded using a roller (the movement of traffic also helps the material to embed).
  4. Following completion of the work there will be some stone loss - this will be removed by a suction sweeper in stages with the first sweep normally taking place within 24 to 48 hours after the work.
  5. After the surface has been laid, traffic signs will be left in place advising of the risk of loose chippings and showing an advisory speed limit.
  6. When the chippings are embedded and no longer loose, any temporary signage will be removed from site.
  7. Depending on traffic levels, further sweeping may be necessary if there is continued stone loss - it can take up to six months for the road to reach its finished state.

What to expect

Surface dressing works will usually be carried out between 8am and 6pm and on-street parking will not be permitted during these times.

The material will remain wet for between 15 and 40 minutes after it has been laid, depending on the temperature and humidity. Please do not drive or walk over roads sprayed with bitumen emulsion until the surface chippings have been spread.

Vehicular access to properties will be possible for most of the time, but you may experience delays while the work is either in progress or immediately after the material has been laid.

Drivers should take extra care and travel slowly when travelling on a road with a new surface dressing.

Pedestrian access to properties will be maintained throughout the works.

Our workforce will be happy to help if you require any assistance.

For a short time, particularly if the weather is warm, there may be small areas of bitumen that are still soft. If you have to walk on the new surface please take care and check your shoes before entering your house or getting into your car. Pets should also be checked in case any bitumen has stuck to them.
