PAVEMENT FAULTING STUDY EXTEND AND SEVERITY OF PAVEMENT FAULTING IN GEORGIA

THE REPORT OUTLINES THE PROCEDURE AND EQUIPMENT THAT WERE USED TO OBTAIN FAULTING DATA ON NEARLY 1,200 LANE MILES OF CONCRETE INTERSTATE PAVEMENT DURING THE SUMMER OF 1971. IT DESCRIBES THE EXTENT AND SEVERITY OF FAULTING ON EACH INTERSTATE ROUTE IN TERMS OF A FAULTING INDEX; THE MAGNITUDE OF FAULTING ON THE INSIDE LANE IS COMPARED TO THE OUTSIDE LANE. CORRELATIONS ARE PRESENTED INDICATING THE EFFECT OF TRUCK TRAFFIC ON FAULTING. COMPARISONS ARE MADE ON THE PROGRESSION OF FAULTING FOR VARIOUS TYPES OF SUBBASE COURSES. EQUATIONS ARE PRESENTED FOR ESTIMATING THE FAULTING INDEX AT ANY LEVEL OF ACCUMULATIVE AVERAGE ANNUAL TRACTOR SEMITRAILER TRAFFIC. REMAINING SERVICE LIFE WITH RESPECT TO FAULTING FOR SOME OF THE MORE SEVERLY FAULTED PROJECTS HAS BEEN CALCULATED AND IS TABULATED. IT WAS CONCLUDED THAT ALL INTERSTATE PROJECTS OF PLAIN CONCRETE PAVEMENT EXHIBIT FAULTING; (2) SEVERITY IS RELATED TO THE TYPE OF SUBBASE USED ON THE PROJECT AND TO TRACTOR-SEMITRAILER COMBINATION TRAFFIC; (3) FAULTING AT THE INSIDE PAVEMENT EDGE IS VIRTUALLY NON- EXISTANT AND IS UNRELATED TO THAT AT THE OUTSIDE EDGE; (4) GRADIENT DID NOT HAVE A SIGNIFICANT EFFECT ON FAULTING; (5) NO SIGNIFICANT DIFFERENCE WAS FOUND IN FAULTING BETWEEN 9 AND 10 INCH PAVEMENT; (6) PLAIN CONCRETE PAVEMENTS CONSTRUCTED ON A CEMENT-STABILIZED SUBBASE TEND TO HAVE LESS FAULTING THAN THOSE CONSTRUCTED ON A BITUMINOUS STABILIZED OR SOIL-CEMENT SUBBASE FOR THE SAME TRAFFIC PARAMETER; (7) FOR A JOINT FAULTING OF 9/32 INCH, ONE OUT OF EVERY THREE SLABS MEASURED ON 9 INCH PAVEMENT WAS CRACKED ON I-85. /FHWA/
