Bitumen Removal
Newly laid road surfaces are characterised by excess binder film that coats the aggregate. This not only results in skid resistance issues but also prevents high-friction surfacing from being applied until traffic has worn away the excess binder from the bitumen-rich surface.
Hydroblasting allows the removal of excess bitumen from brand-new roads at junctions and roundabouts, allowing high-friction surfacing to be laid the next day. This method of accelerating wear has no detrimental effect on the highway surface and yet secures significant cost savings through reductions in contractors' construction schedules.
The hydroblasting process creates no smoke, fumes or dust and the result is a clean, undamaged and almost dry surface. Safe and rapid operation ensures that disruption to traffic flows is kept to a minimum.
