ABSTRACT:
A coal-tar emulsion seal coat is applied atop, spread, and pressed into an asphalt pavement by a continuous rolling technique whereby liquid sealant is carried by and released from a delivery tank extending between the sides of a frame onto the asphalt surface. A first and second set of rollers extending between the frame sides spread and smooth an even pattern of sealant, then a third, smaller, lighter roller provides a finishing and touch-up operation.
