SUBSEALING OF CONCRETE PAVEMENTS

THIS PAPER CONCERNS THE EXPERIENCES IN DISTRICT NO. 4 OF THE NEW YORK STATE DEPARTMENT OF PUBLIC WORKS WITH THE SALVAGE AND RESTORATION OF OLD CONCRETE PAVEMENTS. THESE PAVEMENTS WERE PUMPING BADLY AND DUE TO LOSS OF SUBGRADE SUPPORT WERE CONSEQUENTLY BEING WEAKENED UNDER THE POUNDING OF HEAVIER AND GREATER VOLUMES OF TRAFFIC. THESE EXPERIENCES COVER A PERIOD SINCE 1948. MOST OF THESE PAVEMENTS WERE CONSTRUCTED IN THE LATE 1920'S AND EARLY 1930'S AND HAD BEEN SUBJECTED TO SEVERE USE. ALSO, THEY WERE NOT BUILT TO THE PRESENT STANDARDS OF FOUNDATION AND SUBGRADE CONSTRUCTION, AND WERE LAID ON A VARIETY OF SOILS PREVALENT IN WESTERN NEW YORK. THE METHODS USED, THEIR APPLICATION, AND THE RESULTS OBTAINED, ARE DISCUSSED. THE EFFECT OF THIS WORK, HAS BEEN TO RESTORE THE FOUNDATIONS OF HUNDREDS OF MILES OF PAVEMENT AND ADAPT THEM TO PRESENT DAY TRAFFIC THROUGH WIDENING AND SERVING AS BASES FOR ASPHALTIC CONCRETE OVERLAYS AT AN ECONOMICAL COST. THE NET RESULT HAS BEEN A CONSISTENT REHABILITATION OF A 1,400-MI HIGHWAY SYSTEM MEETING PRESENT DEMANDS OF TRAFFIC. /AUTHOR/
