Pavement crack cleaner

Abstract

Devices for cleaning and preparing pavement cracks for sealing are disclosed. An example device comprises a wire brush assembly for removal of mid and large-sized debris, an air blaster for removal of fine-grained particulate, a heat lance, and a vacuum for controlled removal of debris and particulates. The example device would also have means for attachment to an air compressor.
