The Layer-By-Layer Process Of Adding Anti-Skid To Roads

High Friction Surfacing (often known as “anti-skid”) is the key to safety on the road. A careful approach to application can make a difference between a long-lasting coating and monthly touch-ups. Due to the importance of such coatings, care must be taken to avoid mistakes during application.

Besides improving safety, anti-skid coatings add an additional layer of protection to the road. Considering the amount of rain falling on UK cities all year round, an extra layer can keep roads functioning longer. At Wilson & Scott, we have decades of experience working with different surface materials to ensure high-quality anti-skid coverage, from highways to playgrounds. Let’s talk about the anti-skid road surfacing process in detail.

Two Types Of Anti-Skid Application

The anti-skid material usually consists of about 1 mm to 3 mm aggregate. Depending on the surface, two types of anti-skid application methods are used.

1. Cold Applied Method

This method involves the application of a layer made of epoxy, polyurethane or MMA (methyl methacrylate) with a coat of aggregate (1-3 mm) scattered on top. In order to achieve high quality and durability, a strong and flexible resin with excellent adhesion properties is required.

Cold applied systems can be used between October and April since they don’t work well if applied when humidity levels are high. If the anti-skid layer needs to be applied during the night, the work months are September to May.

2. Hot Applied Method

The hot applied method is more popular in the UK than its cold-applied counterpart. The aggregate is premixed with the bonding agent at high temperatures. Then the technician spreads the mixed solution over the road surface in a single coating. The thermoplastic material creates a thermal bond with the road, ensuring the longevity and durability of the coating.

Hot applied anti-skid surfacing is less sensitive to environmental fluctuations than cold-applied coatings. However, it should ideally still be applied when the weather is warm and dry.

Different Approaches To Different Surfaces

Depending on the surface, a professional installer chooses the best approach to anti-skid surface layering. The type of High Friction Surfacing application also depends on the weather. The approach taken during a summer heatwave, for instance, can be different from work taking place during the early spring rains. Winter application can be problematic because of the cold, wet and erratic weather conditions, so we recommend that organisations check the condition of their roads and arrange resurfacing by the end of October at the latest.

An expert can help you make the right decision about the type of application and the best time for the process.
