Title:
CORRECTION OF PAVEMENT PUMPING BY MUDJACKING, UNDERSEALING, CONCRETE REPLACEMENT, CRACK SEALING AND SUBSEQUENT RESURFACING
Abstract:
FIRST OF THE CORRECTIVE PROCESSES DEVELOPED WAS PAVEMENT PATCHING, WHICH INCLUDED THE REMOVAL AND REPLACEMENT OF BROKEN CONCRETE. NEXT CAME MUDJACKING, A METHOD OF PUMPING A SOIL CEMENT SLURRY UNDER THE PAVEMENT TO PROVIDE SUPPORT. FOLLOWING THESE TWO CORRECTIVE PROCESSES CAME CRACK SEALING, WHEREBY SURFACE CRACKS OF THE BROKEN PAVEMENT WERE POURED WITH AN ASPHALTIC COMPOUND TO PREVENT THE ENTRANCE OF SURFACE WATER. ASPHALTIC UNDERSEALING, WHICH FOLLOWED THE GENERAL MECHANICS OF MUDJACKING, BUT WHICH MADE USE OF A HEAVY PENETRATION ASPHALT FOR PUMPING UNDER THE PAVEMENT WAS THE NEXT GREAT DEVELOPMENT. IN SO FAR AS THIS PROCESS PROVIDED BOTH SUPPORT AND SEALING ACTION IT WAS NOT ONLY CORRECTIVE, BUT ALSO PREVENTIVE. ALL OF THESE, PLUS PAVEMENT RESURFACING WITH BITUMINOUS SURFACE COURSES, PROVIDE THE MEANS BY WHICH THE LONGEVITY OF SERVICEABLE CONCRETE PAVEMENT MAY BE INCREASED. SLAB PUMPING APPEARS TO BE THE MOST BASIC CAUSE OF PAVEMENT FAILURE. /AUTHOR/
