Abstract

A concrete or asphalt profiling apparatus which operates without the use of a wetting agent includes a housing that encloses a plurality of diamond-tipped blades mounted to an arbor and adapted for high-speed rotation, and a suction device in communication with an area enclosed by the housing and configured to generate a suction force so to remove non-wetted dust generated during a profiling operation. During the profiling operation, a mixture of non-wetted dust and air can be drawn from the housing through a conduit and into a container by means of the suction device. An internally supported filter membrane extending into the container separates the concrete dust from the air in the mixture such that a portion of the concrete dust falls into a lower chamber and a portion of the concrete dust cakes on the filter membrane. The apparatus further includes a compressed air port that is adapted to selectively expel compressed air toward the filter membrane to dislodge concrete dust caked thereon.
