Types of road and pavement treatments

Depending on the condition of the road or pavement, we have several treatments available to us.

Road renewal

This is used when the surface or sub-surface layers within the carriageway have deteriorated to a point where they need to be replaced. The existing layer (or layers) is removed and a new surface is laid.

This is our most expensive and will normally last at least 15 to 20 years before a preservation treatment may be required.

Road preservation

This is cheaper than resurfacing and seals the existing surface to extend its life. There are 2 different types of road preservation treatment.

Surface dressing

This type of repair provides more grip and protects  from water and air damage. It is generally used on busy rural or urban roads and lasts up to 10 years.  In advance of the treatment, we fix faults and potholes and then coat the road with an adhesive layer followed by stone chips. This is embedded with the help of vehicles and we sweep the site multiple times over the following week to remove excess stones. This is our most cost effective preservation treatment.

Micro surfacing

This type of treatment is generally used on urban roads and lasts up to 10 years. In advance of the treatment, we fix major faults and potholes before we place a pre-mixed asphalt dressing which is then spread across the road.

Pavement renewal and preservation

Pavement renewal

Similar to road renewal, pavement renewal is when we replace the surface or sub-surface layers within the pavement that have been found to have significant deterioration. The existing deteriorated layer(s) are removed, and a new surface is laid.

This is our most expensive treatment and will normally last at least 15 to 20 years before a preservation treatment may be required.

Pavement preservation - Slurry seal

This treatment can be used on pavements with minor defects such as surface cracking. In advance of the treatment we repair any isolated major faults, jet wash and weed spray the area. The application of a cold pre-mixed asphalt dressing is then completed. This is the most cost effective and least disruptive option.
