摘要
An improved method of removing the rubber coating deposited on the surface of an airport runway by the tires of an aircraft comprises the steps of forming a plurality of solid stream 0 DEG to 15 DEG streams of high velocity water in a closely adjacent parallel relationship, directing the streams to impinge on a surface to be cleaned at an angle of 0 DEG to 35 DEG to the vertical plane, and moving the streams longitudinally of the surface to be cleaned while simultaneously transversely reciprocating the streams a distance at least equal to the transverse distance between adjacent streams. The apparatus consists of a spray conduit having a plurality of solid stream 0 DEG nozzles mounted thereon and means for reciprocally driving the conduit longitudinally of itself a distance at least equal to the longitudinal distance between adjacent nozzles.
