Title:

AN INVESTIGATION OF PHYSICAL PROPERTIES OF AN EPOXY BONDING COMPOUND FOR COMPOSITE BEAM BRIDGE CONSTRUCTION

Accession Number:

00215779

Record Type:

Component

Abstract:

THIS PAPER PRESENTS INFORMATION ON THE BASIC PROPERTIES OF AN EPOXY RESIN BONDING COMPOUND WHICH IS BEING STUDIED FOR USE AS A STRUCTURAL CONNECTION FOR HIGHWAY CONSTRUCTION, INCLUDING COMPOSITE BEAM BRIDGES. SEVERAL IMPORTANT PHYSICAL PROPERTIES OF THIS RESIN HAVE BEEN DETERMINED, SUCH AS THE TENSILE, COMPRESSIVE, SHEAR, FLEXURAL FATIGUE, AND TORSIONAL FATIGUE STRENGTH OF THE RESIN AS A PLASTIC, AND ALSO ITS MODULUS OF ELASTICITY AND COEFFICIENT OF EXPANSION. ADDITIONAL TESTS ON THE RESIN AS AN ADHESIVE INCLUDED THE SINGLE SHEAR STRENGTH AND TENSILE STRENGTH BETWEEN STEEL AND CONCRETE, EFFECT OF FREEZE-THAW CYCLING, EFFECT OF CONCRETE CURING ON ADHESIVE BOND, CONSISTENCY OF ADHESIVE, STRENGTH DEVELOPMENT OF ADHESIVE, STORAGE LIFE OF ADHESIVE, WORKING LIFE OF LIQUID ADHESIVE, AND OTHER RELATED PROPERTIES. THE RESULTS SHOW THAT AN EPOXY RESIN FORMULATION SATISFYING THE STRENGTH DEMANDS OF A COMPOSITE BEAM BRIDGE CAN BE ACHIEVED, SUBJECT TO THE RESTRICTIONS IMPOSED BY THE TESTING PROGRAM. HOWEVER, FURTHER STUDIES OF PERFORMANCE AND CHARACTERISTICS ARE NECESSARY BEFORE THE SELECTED EPOXY RESIN FORMULATION CAN BE APPROVED FOR USE AS A CONNECTOR; SUCH AS CREEP, FATIGUE ON GLUED JOINTS, IMPACT, STRENGTH GAIN UNDER VARIOUS TEMPERATURE CONDITIONS, AND DURABILITY. /AUTHOR/ EQUIPMENT IS DESCRIBED. BOTH OVERLAY SYSTEMS HAVE BEEN SHOWN TO BE EFFECTIVE IN SEVERAL LARGE-SCALE FIELD TESTS. /AUTHOR/ HORIZONTAL LOAD AND HYDRAULIC CONTROLS FOR MAINTAINING A CONSTANT RATE OF SHEAR.
