CONDITION SURVEYS OF BITUMINOUS RESURFACINGS OVER CONCRETE PAVEMENTS

A TECHNIQUE IS DESCRIBED FOR MAKING AND ANALYZING CONDITION SURVEYS OF BITUMINOUS RESURFACINGS OVER CONCRETE PAVEMENTS. SUCCESSIVE SURVEYS PROVIDE A BASIS FOR EVALUATING THE PERFORMANCE OF DIFFERENT RESURFACING TYPES. SURVEY SECTIONS INCLUDE ABOUT 1,000 FEET OF TYPICAL PAVEMENT. THE LOCATION AND EXTENT OF ALL DEFECTS ARE MEASURED IN THE FIELD AND RECORDED DIRECTLY ON FORMS PREPARED FOR THAT PURPOSE. ALL CRACKS ARE CLASSIFIED BY WIDTH AND BY THEIR MOST LIKELY CAUSE, WHICH CAN USUALLY BE DETERMINED QUITE ACCURATELY BY OBSERVATION OR BY INSPECTION OF CONSTRUCTION AND MAINTENANCE RECORDS. INDICES ARE COMPUTED FROM THE FIELD DATA AND ARE USED TO COMPARE THE PERFORMANCE OF THE DIFFERENT RESURFACINGS. THEY ARE COMPUTED FOR THE INCIDENCE OF CRACKING OVER TRANSVERSE AND LONGITUDINAL JOINTS, OVER JOINTS BETWEEN CONCRETE AND ADJACENT BITUMINOUS SHOULDERS, AT CONSTRUCTION JOINTS IN THE RESURFACING, AND OVER CRACKS AND OTHER DEFECTS IN THE UNDERLYING CONCRETE. THE SURVEY METHOD DIFFERS FROM THOSE APPLICABLE TO CONCRETE PAVEMENTS OR TO BITUMINOUS SURFACES ON FLEXIBLE BASES. DEFECTS MAY BE CAUSED BY DETERIORATION OF EITHER THE CONCRETE OR THE BITUMINOUS RESURFACING, OR BY THE DISSIMILAR PROPERTIES OF THE TWO MATERIALS. THE METHOD HAS BEEN DEVELOPED AND REFINED THROUGH 2 YEARS OF DATA COLLECTING AND HAS BEEN SUCCESSFULLY USED ON REPEATED SURVEYS OF 25 TEST SECTIONS TOTALING OVER 6 MILES IN LENGTH. /AUTHOR/
