Using a process called micro asphalt, a liquid mix of stone, cement and bitumen, the treatment is applied to seal the road surface, preventing any damage and filling in any potholes.
The work is part of our ongoing highways capital programme and is a preventative treatment to maximise the road’s lifespan. The micro asphalt repair programme is part of this year’s £27 million investment in roads, pavements and transport across the county.
Micro asphalt repairs can be carried out in cooler weather conditions. The weather does need to be dry which can lead to last minute changes to the programme, as some repairs may have to be postponed if it's raining.
The treatment can be completed in around 20 minutes, so there should be minimal delays and inconvenience for local road users. Leaflets delivered door-to-door and temporary road warning signs will be used to inform residents living in areas where the micro-asphalt repairs will be carried out.
In Derbyshire, we focus the repair on cul-de-sacs on residential estates and use it as a preventative more cost-effective treatment to prolong the lifespan of the road.

Councillor Charlotte Cupit, Cabinet Member for Highways Assets and Transport said:
“Micro asphalting is just one part of our wider highways capital programme of road repairs. It’s a way to seal the road surface against water and protect it, which will then help to extend the life of the road surface.
“It’s done as more of a preventative treatment at the most cost effective time, which is why these 63 roads have been selected following assessment.
“The initial treatment settles over several weeks with traffic use to create a new road surface.
“Alongside this part of the programme, we are also continuing our wider programme of both full and sectional road resurfacing and pothole repairs.”
To help minimise delays and inconvenience local residents are advised to:
- park cars on a neighbouring street to avoid any last minute delays to the repair programme
- try to avoid walking on the surface until it has dried
- take extra care driving on the new surface until it has fully dried
- avoid any sudden braking or steering manoeuvres on the new surface until it has fully dried
- take care at junctions where give way and centre line road markings have been replaced.
Subject to weather conditions, the repair programme is expected to be completed in late August.
