Target Traffic patch consists of specially modified Portland cement and aggregates combined in closely controlled proportions to give a rapid setting material for the repair of concrete. The product meets the requirements of ASTM C928 for very rapid hardening concrete repair materials. The rapid strength gain properties are maintained at temperatures as low as 3°C (37°F). The product contains no calcium chloride or other admixtures likely to accelerate the corrosion of reinforcing steel. Traffic patch is available in Fine and Coarse aggregate gradations. The traffic Patch Fine incorporates polypropylene fibres and is intended for use in patches up to 25mm (1 inch) thick. The Traffic Patch Coarse incorporates 30mm long steel fibres and is designed for use in patches with thicknesses of more than 25mm (1 inch). Traffic Patch is designed for use as a repair material for cast-in-place or precast concrete where rapid setting and strength gain of the repair are required. Typical applications include patching of bridge decks, roads, curbs, sidewalks, parking decks and warehouse floors where the repaired area must be returned to normal service conditions within two hours of placing the repair mix.
