EVALUATION OF COLD PLANNERS FOR GRINDING PCC PAVEMENTS

This report describes attempts by two contractors to use cold planing equipment (CMI Rotomills) to restore riding quality to faulted PCC pavements. It was found that while the equipment could remove substantially all faulting and greatly improved riding quality, there was severe damage to the concrete adjacent to random cracks and transverse joints in spite of considerable effort to prevent it. Because of this damage, the equipment as tested was not considered satisfactory for grinding PCC pavements. /FHWA/
