SLAB BREAKING AND SEATING ON WET SUBGRADES WITH PNEUMATIC ROLLER
THIS PAPER REPORTS ON A LONG-RANGE FIELD STUDY TO DETERMINE THE PRACTICABILITY OF USING A PNEUMATIC TIRE 50- TON ROLLER TO BREAK AND SEAT OLD CONCRETE PAVEMENTS BEFORE OVERLAYING WITH HOT-MIX ASPHALTIC CONCRETE. THE METHOD OF STUDY IS A COMPARATIVE ANALYSIS OF THE BEHAVIOR, UNDER TRAFFIC, OF VARIOUS ROADWAY SECTIONS EMPLOYING DIFFERENT BREAKING AND SEATING TECHNIQUES OF THE 50-TON PNEUMATIC ROLLER AND AN IMPACT HAMMER ON A CONSTRUCTION PROJECT GENERALLY HAVING A WET SUBGRADE CONDITION. OBSERVED RESULTS AND FIELD DATA ARE SHOWN DURING THE BREAKING AND SEATING OPERATION AND AFTER ONE AND TWO YEARS OF TRAFFIC TO SUPPORT THE CONCLUSION THAT THE 50-TON ROLLER SHOULD BE USED IN CONJUNCTION WITH AN IMPACT HAMMER, USING THREE ROLLER COVERAGES FOR SLAB BREAKING AND SEATING. /AUTHOR/
