Professional material for the device of longitudinal and transverse technological joints of asphalt concrete pavements of roads, interface joints, waterproofing of joints of prefabricated reinforced concrete structures
Sealing of technological joints of road surfaces made of hot asphalt concrete mixes (tape "Brit" A) and from crushed stone-mastic asphalt mixes (tape "Brit" ShchMA), junctions to road surfaces, sidewalks, buildings and structures, curbstones, drainage trays, foundations , rails, hatches of manholes and arrangement of joints of foundation blocks and panels. The sealing effect is achieved as a result of the melting of the tape material under the influence of the high temperature of the mixture and the formation of a protective layer during compaction, as a result of which the water saturation of asphalt concrete in the seam zone is reduced and the formation of technological cracks in the coating is prevented.
Advantages
Reduction of water saturation parameters in the cold joint zone by an average of 45%.
Excellent resistance of interface seams to long freeze-thaw cycles.
Reliable sealing of joints - the strength of joints using Brit tape is twice as high as adhesions made using traditional technology.
There is an option with an additional adhesive layer.
Simple unified application technology.
