Resin Bound and Bonded Surfacing
The Resin Bound and Resin Bonded Surfacing provide highly decorative and functional systems for exterior pavement surfacing
Difference Between Resin Bound and Resin Bonded Surfacing
Resin Bound and Bonded Surfacing – similar names, very different materials. The similarity of the names can be a cause of confusion, and while both components contain resin and visible kiln-dried aggregate, their appearance and often their uses are slightly different.
Resin Bound Surfacing
Surfacing described here, comprises kiln-dried aggregate bound with clear resin, typically polyurethane and is laid from 15mm to 20mm thickness. Aggregate is coated with resin during mixing and resin exposed to sunlight will perform differently, depending on the type of resin used. Resin bound surfacing are formulated with UV stable HDI resins and will not discolour or degrade when exposed to sunlight. MDI resins yellow, darken and have been seen to degrade after exposure to sunlight. Resin Bound Surfacing is porous, and we can use it as part of a Sustainable Drainage Systems (SuDS) compliant pavement construction.
Resin Bonded Surfacing
Resin Surfacing comprises a layer of polyurethane resin with kiln-dried aggregate embedded in the freshly applied resin layer, This kind of surfacing is typically laid on concrete or asphalt at a thickness of approximately 3mm.
