Proscreed

Coldmac Proscreed is a new concept in crack repair systems designed to repair cracks and joints up to 40mm wide. It is a 2-part screed-applied system, suitable for all types of bituminous surface course and road – including roundabouts, bends and areas treated with high friction surfacing. Its skid resistance is designed to equal or exceed the surrounding surface, and it will maintain a high skid resistance throughout its long life.

proscreed Part A is a specially formulated polymer bitumen blend incorporating high PSV aggregate and fibres, which fills and seals the crack or joint, and acts as a stress absorbing medium for the high friction surface layer (Part B).

Part B is a thermoplastic resin blend incorporating calcined bauxite or other high PSV aggregate, which spans the crack or joint, providing a textured high friction surface.

During application of Part B, the screeding temperature allows the two components to fuse together over the crack area, to give a previously unavailable combination of flexibility and surface texture retention. The finished repair achieves a minimum texture depth of 1.5mm and an SRV >60 (>65 for HF grade)
