RESEALING JOINTS AND CRACKS IN CONCRETE PAVEMENTS WITH HOT-POURED RUBBER-ASPHALT

IN VIEW OF THE OBVIOUS NEED FOR A MAJOR PROGRAM OF RESEALING JOINTS AND CRACKS IN CONCRETE PAVEMENTS, THE MAINTENANCE DIVISION OF THE MINNESOTA HIGHWAY DEPARTMENT, IN COOPERATION WITH THE DIVISION OF MATERIALS AND RESEARCH, INITIATED AN EXPERIMENTAL PROJECT IN 1949 TO STUDY THE CUTTING, CLEANING, AND RESEALING OF JOINTS AND CRACKS. THE STUDY INCLUDED METHODS, EQUIPMENT, MATERIALS AND COSTS. IN VIEW OF THE APPARENTLY SUCCESSFUL RESULTS OBTAINED ON THE EXPERIMENTAL PROJECT, THE MAINTENANCE DIVISION AWARDED CONTRACTS FOR SEALING APPROXIMATELY 85 MI. OF PAVEMENT WITH HOT-POURED RUBBER-ASPHALT IN THE 1950 SEASON. THE PRINCIPAL BID ITEM WAS FOR JOINT CLEANING AND RESEALING, THE BID PRICE PER POUND TO INCLUDE 'ALL MATERIAL FURNISHED, AND ALL OPERATIONS NECESSARY FOR, OR INCIDENTAL TO CUTTING, CLEANING AND FILLING' JOINTS AND CRACKS. THE OVERALL RESULTS OBTAINED WERE SO SATISFACTORY THAT THE DEPARTMENT DECIDED TO CONTINUE THE PROGRAM OF REHABILITATION OF ITS OLD CONCRETE PAVEMENTS AND 333 MI. WERE PLACED UNDER CONTRACT FOR 1951. THIS PAPER DESCRIBES THE EXPERIMENTAL PROJECT AND THE MATERIALS, METHODS AND EQUIPMENT DEVELOPED TO ACCOMPLISH ECONOMICALLY THE WORK UNDER CONTRACT. /AUTHOR/
