Types of road and pavement treatments

Depending on the condition of the road or pavement, there are different treatments we can use.

Road renewal

For when the surface or other layers of the road have deteriorated to a point where they need to be replaced. The existing layers are removed and a new surface is laid.

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

Re-tread

We recycle the existing surface - mix it with bitumen and put back on the road.

It is given time to set then a further surface treatment is put on to give a permanent road surface, seal it from water and protect the finished road structure.

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

Generally used on busy rural or urban roads. It provides more grip, protects from water and air damage and lasts up to 10 years. We fix faults and potholes first, then coat the road with stone chips. Vehicles driving on the road help these set, and we come back to sweep the site to remove excess stones.

In some places, we may use a product called LockChip, this is a coating to seal the new surface.

This is the most cost effective preservation treatment.

Micro surfacing

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

Pavement renewal and preservation

Pavement renewal

Similar to road renewal, pavement renewal is when we replace the surface or other layers of the pavement that have significantly deteriorated. The existing layers 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 needed.

Pavement preservation - slurry seal

This treatment can be used on pavements with minor defects such as cracking. First we fix all major faults, jet wash and spray weeds in the area, then put on a cold pre-mixed asphalt dressing. This is the most cost effective and least disruptive option.
