High-performance materials deliver a multi-layer crack resisting binder/surface course that is particularly suited to overlaying concrete carriageways.
Performance tests show that it has a low air void content and high deformation resistance compared to traditional asphalt surfacing.
The solution also delivers Highways England’s highest level of wheel rut resistance, level three.
Its design uses specialised bitumens and incorporates best-in-class polymer technology to give it a flexibility that enhances fatigue resistance by absorbing traffic vibration.
With its relatively low surface texture and extreme density, it also effectively protects the surface it covers from water damage.
It is available in 10mm, 14mm and 20 mm nominal sizes and can be laid between 30mm and 150mm thick using a traditional asphalt paver with a minimum 6-10 tonne roller.
Special attention should be given to compaction at the joints, which should be cut and painted with a bituminous joint paint to maintain resistance to the tensile stresses of turning vehicles.
