What is Micro Surfacing?

Micro Surfacing is a fast, effective and economical way to preserve and protect the road surface and is a cost effective road surface treatment solution that is applied to worn carriageways.


It improves skid resistance and fills any small imperfections in the surface. It is ideal for urban and rural roads where a hard wearing and longer lasting surface is required, providing benefits to the road user, environment and local highways authorities. The process uses a specialist dedicated machine which mixes the aggregate and bitumen on site. The machine is then used to apply the material to the road surface. Two coats are normally laid, resulting in a new surface up to 20mm thick, smoothing out bumps in the existing surface. The surface is swept after laying and again two days later to remove excess stone, repeated if required.


Manhole covers and other ironworks will be raised and road markings replaced a few days after laying the surface to allow it time to ‘bed in’. Micro Surfacing is normally undertaken during the summer months as it best adheres to a dry road surface. This means the treatment cannot normally be applied during wet weather.


What benefits do road users see?

Micro Surfacing is quick to apply and often requires only temporary road closures. It is normally ready for traffic to travel on the new surface within 20-30 minutes, reducing delays to road users.


The surface is ideal for urban and rural locations, improving safety through improved skid resistance, evening out bumps in the carriageway and providing a durable, uniform finish. It creates a seal, preventing water from penetrating the road surface, prolonging the life of the road.


Does the product have any environmental benefits?

Micro Surfacing uses cold materials. This means that no hot material is used on site, improving safety and reducing fumes. As the bitumen and aggregate components are mixed on site within the machinery, transport and mix cost and fuel savings are made. This also contributes to the process having a lower carbon footprint than other forms of asphalt surfacing.


What should I do when the works are taking place?

During the operations, please ensure that your vehicles are not parked on the highway as the operations will require full access at all times to the road. ‘No Parking’ signs will be erected throughout sites to advise residents of the times when vehicles should be removed.


Please do not walk on the freshly laid materials, because it may stick to your shoes and can be transferred to carpets, wooden floors, etc. Please do not drive directly onto the freshly laid materials and observe the traffic control measures in place at all times.


If you have any queries on the day of application then please seek advice from the crew who will be more than willing to answer your questions.
