CONTINUOUSLY-REINFORCED CONCRETE PAVEMENTS IN PENNSYLVANIA' A SIX-YEAR PROGRESS REPORT
AFTER FIVE AND SIX YEARS OF SERVICE LIFE, THE TWO CONTINUOUSLY-REINFORCED CONCRETE PAVEMENTS IN YORK AND BERKS COUNTIES, PA., HAVE SUPPLIED DATA SUFFICIENT FOR EVALUATING THE EFFECTS OF THE VARIABLES UNDER WHICH THE PAVEMENTS WERE CONSTRUCTED. THESE PROJECTS, ON INTERSTATE ROUTES 83 AND 78, RESPECTIVELY, ARE LOCATED ON HEAVILY-TRAVELED ARTERIES WHERE APPROXIMATELY ONE-THIRD OF THE TRAFFIC IS RATED AS HEAVY TRUCK. THE BACKGROUND HISTORY OF THE TWO PROJECTS IS REVIEWED BRIEFLY AND THE DESIGN VARIABLES OF EACH PAVEMENT ARE DESCRIBED. SIGNIFICANTLY DIFFERENT DATA ARE OBTAINED FROM THESE VARIABLES, PARTICULARLY FROM THE SEASON OF PAVING. INCLUDED ARE DATA ON CRACK FREQUENCY, CRACK WIDTH, TRAFFIC COUNT, AND ROUGHNESS SURVEYS. ANNUAL END MOVEMENT AND PERFORMANCE OF THE TERMINAL JOINTS ARE DESCRIBED. SHORTLY AFTER COMPLETION OF THE BERKS COUNTY PROJECT, SEVERAL WIDE CRACKS DEVELOPED AND A SUBSEQUENT INVESTIGATION SHOWED THESE TO BE LAP FAILURES, FOR THE MOST PART. SATISFACTORY REPAIRS WERE MADE, BUT IN 1960, A PORTION OF THE 7-IN. PAVEMENT HAD TO BE REPLACED, ESSENTIALLY BECAUSE OF FOUNDATION FAILURE AND POOR SUBBASE DENSIFICATION. THE INVESTIGATION ACCOMPANYING THIS REPAIR WORK IS REPORTED IN DETAIL. THE YORK COUNTY PAVEMENT TO DATE IS PERFORMING ADEQUATELY. THE RELATIVE PERFORMANCE OF BOTH PAVEMENTS IS DUSCUSSED AND A SUGGESTED DESIGN FOR CONTINUOUSLY-REINFORCED PAVEMENTS IS OFFERED. /AUTHOR/
