Carriageway micro asphalt
Carriageway micro asphalt is a road surface treatment designed to restore texture, improve skid resistance, and extend the life of existing roads.
The specific benefits are that it:
- is a cost-effective treatment applied to worn or aged road surfaces
- seals the surface, fills minor imperfections, and provides a new, smooth running layer
- improves ride quality and overall appearance while helping to prevent further deterioration
Micro asphalt treatments are typically carried out between April and September, as the process requires warm and dry weather conditions.
Before we start
Advance warning signs (yellow) will be placed on affected roads at least seven days before work begins.
Residents on roads due to be treated will receive information explaining what to expect. If you need vehicle access during the day, please move your vehicle to another location before works start.
During the works
To ensure safety, we use traffic management such as road closures, convoy systems, or stop/go boards.
The micro asphalt material is laid in one or two thin layers, which set and cure relatively quickly.
Please avoid walking or driving through the freshly laid surface until it has cured, as it can mark shoes, tyres, and nearby surfaces.
After the works
The site will be swept to remove any loose material once the surface has cured.
Ironworks such as manhole covers and drainage gullies will be adjusted to match the new surface levels where necessary.
The new surface may appear darker or textured immediately after application this is normal and part of the curing process.
As traffic moves over it, the surface will bed in, lighten in colour, and take on a smoother, more uniform appearance over time. Road markings will be repainted as soon as possible.
Weather and scheduling
Micro asphalt surfacing can only take place in dry conditions. If the weather changes or rain is forecast, works may need to be rescheduled at short notice to ensure quality and safety.
