CONTINUOUSLY-REINFORCED CONCRETE PAVEMENTS IN PENNSYLVANIA

THE HAMBURG PROJECT IN BERKS COUNTY, PA., HAS ATTAINED ONE YEAR OF SERVICE PERFORMANCE. THE YORK PROJECT IS NOW TWO YEARS OLD, ALTHOUGH IT, TOO, HAS BEEN OPENED TO TRAFFIC ONLY ONE YEAR. THIS REPORT DESCRIBES THE GENERAL CONDITION OF EACH PROJECT AND PRESENTS THE COMBINED RESULTS OF A COMPREHENSIVE CRACK FREQUENCY AND WIDTH SURVEY ON BOTH PAVEMENTS. A STUDY IS MADE OF THE DIFFERENT CRACK PATTERNS EVOLVED AS A RESULT OF PAVING IN OPPOSITE SEASONS OF THE YEAR. FURTHER ANALYSIS IS MADE OF THE EFFECT OF VARIOUS PAVEMENT THICKNESSES UPON SERVICE PERFORMANCE OF THE HAMBURG ROADWAY AND THE EFFECT OF VARIOUS DEPTHS OF SUBBASE MATERIAL. A SCATTERED NUMBER OF DETRIMENTAL TRANSVERSE CRACKS APPEARED ON THE HAMBURG PROJECT WITHIN SEVERAL MONTHS AFTER COMPLETION. THE NATURE OF THESE CRACKS AND THE INVESTIGATION TO DETERMINE THEIR CAUSE IS DESCRIBED, TOGETHER WITH AN ACCOUNT OF THE SUBSEQUENT REPAIR OF THESE DAMAGED AREAS. THE SPECIFICATIONS FOR THESE REPAIRS ARE OUTLINED, EMPHASIZING THE NECESSARY PRECAUTIONS REQUIRED FOR THIS WORK. A DETAILED DESCRIPTION IS GIVEN OF THE METHODS EMPLOYED IN PAVEMENT REMOVAL, IN RESTORING THE CONTINUITY OF THE STEEL, AND IN REPLACING THE DAMAGED CONCRETE. /AUTHOR/
