Surface dressing is a quick, relatively low cost way of improving the condition and skid resistance of the road surface. It involves spraying bitumen (a tar like substance) over the surface of the existing carriageway and covering it with a layer of stone chippings. As the bitumen sets the stone chippings are compacted in by the use of a roller and further assisted by vehicles travelling over the newly laid surface. Any excess chippings are then swept up.
In Calderdale we regularly inspect our highways to ensure they are safe and to monitor their condition and rate of deterioration. Roads that would be suitable for surface dressing are highlighted throughout the year and are then included in the surface dressing programme which takes place in May – September the following year.
Advantages of surface dressing
- It provides a good skid resistance;
- It prevents water from seeping into the road foundation and weakening it, improves the roads surface and substantially delays the need for the complete rebuilding;
- It is up to ten times cheaper than other methods of restoring road surfaces;
- Traffic can be allowed to run on the new surface almost immediately.
Disadvantages of surface dressing
- Works are weather dependant, it is not possible to surface dress roads during wet weather;
- Drivers need to travel slowly on the newly laid surface to prevent chippings being dislodged.
What we / our contractors will do
- Give advance notice of works to residents and drivers wherever possible.
- Provide advisory and warning signs from the time they start work to the time the road is ready for normal use.
- Sweep the roads and footpaths to remove the loose chippings
- Ensure that the work is carried out to a high standard
- Minimise hazards and disruption to traffic through correct use of traffic control.
- Ensure that any complaints are investigated and appropriate action taken.
What you can do
- Ensure that your vehicle is not left on the road which is to be treated;
- Try to avoid inviting visitors or arranging deliveries when work is to take place;
- Keep to the recommended speed limit on recently treated roads;
- Take care not to walk on newly dressed roads until the bitumen has set properly and remove outdoor shoes before entering the home.
- Bitumen can be removed from shoes, wheels and clothing with the help of turpentine or white spirit.
Footway Slurry Seal
Slurry seal is a quick, low cost treatment which is used to improve the condition and appearance of footways whilst prolonging their life expectancy and delaying the need for more expensive reconstruction works.
The process involves:
- Spraying the area so that it is clear of weeds;
- Jet washing or cleaning the areas to be treated;
- Lifting of ironworks;
- Ensuring that undergrowth is away from footway edges;
- Masking of kerbs and or ironworks;
- Laying of material which is a wet black mixture spread over the footway using brushes and squeegees;
- Sweeping/picking tape up off covers and general clear up of the site.
If you have any vegetation overhanging the footway please ensure that this is cut back prior to works being carried out.
Residents will be informed that slurry sealing is due to take place in their area but it is difficult to give exact dates as works are weather dependant.
Micro asphalt is a liquid treatment, similar to slurry sealing, which is applied to carriageways, either mechanically or manually. The treatment provides improved skid resistance whilst improving road condition, preventing ingress of water and delaying the need for more costly road repairs. This treatment is quick to apply and can be driven on within a short space of time. This treatment is weather dependant and works will be delayed during wet conditions.
