PREPARING OLD PAVEMENTS FOR RESURFACING WITH 50-TON COMPACTOR

USE OF A 50-TON COMPACTOR ON A 4-MILE HIGHWAY PROJECT IN PREPARATION FOR WIDENING AND RESURFACING, WITH ASPHALT CONCRETE, AN OLD PORTLAND CEMENT CONCRETE PAVEMENT CONSTRUCTED IN 1924, IS DESCRIBED. A SUMMARY OF THE METHODS OF PREPARATION OF OLD CONCRETE PAVEMENTS DURING THE PAST 20 YEARS IS GIVEN AND THE INHERENT FAULTS OF REFLECTION CRACKS AND SUBSIDENCE OF THE NEW PAVEMENT ARE DISCUSSED AS A PRELIMINARY REASON FOR THE TRIAL OF THE COMPACTOR METHOD OF PREPARATION OF THE OLD PAVEMENT. A DESCRIPTION OF THE PROJECT IS GIVEN, STARTING WITH THE OLD CEMENT CONCRETE PAVEMENT, THE LAYERS OF SELECTED ROADWAY BORROW AS WIDENING FOUNDATION MATERIAL ON WHICH WAS CONSTRUCTED A 6-IN. LAYER OF CEMENT-TREATED BASE AND THE LAYERS OF BASE AND TOP COURSE AGGREGATES OVER THE OLD CONCRETE PAVEMENT AS WELL AS THE WIDENED AREAS BEFORE THE ASPHALT CONCRETE PAVEMENT WAS CONSTRUCTED. THE COMPACTOR AND ITS USE ARE DESCRIBED, AS WELL AS THE ACTION OF THE COMPACTOR ON THE CONCRETE SLABS THAT ARE ROCKING OR THAT BRIDGE SUBSIDED SUBGRADE AREAS. SKETCHES INDICATE THIS ACTION AND THE SUBSEQUENT DESIRABLE RESULTS OBTAINED AS THE CONCRETE SLABS ARE BROKEN UNDER THE WEIGHT OF THE COMPACTOR. /AUTHOR/
