RESIN BONDED
Resin bonded surface dressing is a hard wearing, easy to use cold applied polyurethane/epoxy resin surface dressing used for bonding specially selected aggregates to macadam, asphalt, concrete or metal surfaces. It can be applied to new constructions or to existing surfaces.
Resin surface dressing can be used with a wide range of natural and pigmented aggregates for both decorative and slip resistant dressings.
The cured resin surface dressing systems give a durable, textured surface which is ideal for pedestrian areas, pathways, cycle ways, car parks, traffic calming, colour demarcation, and anti-skid applications.
Using resin bonded surface dressing means no sticky black binder will be seen as can happen with conventional bituminous surface dressing systems.
PERFORMANCE
The durability of resin surface dressing will depend on site conditions and it is anticipated that the surface will have a similar service life to that of conventional surfaces made with the same aggregate. Resin surface dressing is resistant to the weathering effects of UV radiation, from sunlight to softening or degradation of oils, fuels and some commonly used solvents.
APPLICATION
The resin components are simply mixed with a drill powered mixer and is then spread over the surface using a serrated edge squeegee at a rate of 1.5 – 1.8kg per m2 depending on surface condition and aggregate used.
Aggregate is then broadcast to excess over the spread resin by hand so that the resin layer is fully covered. Typical application rates for 1-4mm aggregates are 8-10kg per m2. Once the resin is sufficiently cured, the excess aggregate is removed by hand brushing or mechanical sweeping, to ensure all the loose stone is removed.
SURFACE PREPARATION
Porous surfaces should be sealed prior to resin application sealing compound and be of sound construction and of regular profile. Metal surfaces should be treated with a suitable metal primer.
BASE COURSE
The depth and composition of the underlying construction, will be dependent upon whether the surfacing is intended for vehicular or pedestrian traffic. A typical base build up for pedestrian and light traffic areas are bituminous – hot rolled asphalt to BS594.
