CONTROL OF REFLECTION CRACKING IN BITUMINOUS RESURFACING OVER OLD CEMENT-CONCRETE PAVEMENTS

THIS PAPER DESCRIBES THE CAUSES OF REFLECTION CRACKING AND SEVERAL EXPERIMENTAL TECHNIQUES FOR ITS CONTROL. PARTICULAR EMPHASIS IS PLACED ON THE STRAINS IMPOSED IN BITUMINOUS- CONCRETE SURFACES BY THE HORIZONTAL MOVEMENT OF CONCRETE SLABS AT JOINTS AND CRACKS DUE TO TEMPERATURE CHANGES. MEASUREMENTS WERE MADE OF JOINT OPENINGS AND CLOSINGS IN CONCRETE PAVEMENTS TO DETERMINE THE MAGNITUDE OF STRAINS IMPOSED UPON THE RESURFACING. CONSTANT-STRAIN AND CONSTANT- STRESS TENSION-TEST PROCEDURES WERE DEVELOPED TO DETERMINE THE STRENGTH AND ELONGATION CHARACTERISTICS OF THREE TYPES OF BITUMINOUS CONCRETE AT WINTER TEMPERATURES. TEST-ROAD SECTIONS ARE DESCRIBED IN WHICH SEVERAL METHODS OF JOINT TREATMENT AND REINFORCING WERE INCORPORATED. THESE EXPERIMENTAL DEVICES INCLUDED PLUGGING CERTAIN EXPANSION JOINTS WITH CEMENT GROUT OR A STABILIZED-SOIL MIX, BREAKING THE BOND BETWEEN BITUMINOUS CONCRETE AND CEMENT CONCRETE AT JOINTS, PLACING METAL PLATES ON CONCRETE, AND REINFORCING THE BITUMINOUS CONCRETE WITH VARIOUS TYPES OF METAL PLACED EITHER ON THE CONCRETE OR BETWEEN BINDER AND SURFACE COURSES OF BITUMINOUS MIX. THE PAPER CONCLUDES THAT REFLECTION CRACKING CAN BE ELIMINATED ONLY BY THE DEVELOPMENT OF NEW TECHNIQUES FOR HANDLING JOINTS IN RESURFACING. PRELIMINARY CONCLUSIONS ARE DRAWN AS TO THE EFFECTIVENESS OF THE EXPERIMENTAL TECHNIQUES DESCRIBED. /AUTHOR/
