The M6 J16-19 SMP requires all current surface course to be replaced to a depth of 35mm-50mm. The work generates the need to put down temporary white lining when laying the new surface course, which when removed can cause surface damage. Also, there can be customer complaints regarding the state of temporary road markings through Smart Motorways roadworks due to ghosting caused when blacking out and removal of existing white lines.
Traditionally lines are blacked out with an anti-skid paint. Over time the skid resistance wears off and the black lines are visible and confusing to the road user, particularly in low level sunlight or wet conditions.
QMS HyperLine was the chosen product which is a combination of a cold, spray applied Waterborne Acrylic Resin and two sizes of Recycled Glass Beads, producing a road marking that is environmentally sustainable with high levels of performance and productivity. The process was first used on the project in February 2018.
