ABSTRACT:
A method of repairing a road surface includes providing a hopper mounted on a spreading vehicle and means to spread material carried in the hopper over depressed areas of the road surface to fill them with the material. At ambient temperature, a batch of patching slurry is mixed comprising aggregate, asphalt emulsion, water, Portland cement, and a retarding agent operative to increase a break time of the patching slurry, and the batch is deposited into the hopper. The spreading vehicle is maneuvered to spread the patching slurry successively over a plurality of depressed areas until the hopper is empty. The ingredients of the patching slurry are adjusted to provide a patching slurry having a break time sufficiently long to allow the hopper to be emptied before the patching slurry begins to set, and sufficiently short to allow traffic to pass over a filled depressed area within a desired time.
