OBSERVATION AND ANALYSIS OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENT

THIS REPORT IS THE RESULT OF A COOPERATE EFFORT BETWEEN THE TEXAS HIGHWAY DEPARTMENT AND THE UNIVERSITY OF TEXAS, CENTER FOR HIGHWAY RESEARCH. RESEARCH PROJECT 3-5-63-56, ENTITLED DEVELOPMENT OF METHODS FOR COMPUTER SIMULATION OF BEAM-COLUMNS AND GRID-BEAM AND SLAB SYSTEMS HAS PRODUCED POWERFUL NEW ANALYTICAL METHODS OF SLAB ANALYSIS. THESE ANALYTICAL TOOLS WERE USED TO ANALYZE 21 CONTINUOUSLY REINFORCED CONCRETE PAVEMENT TEST SECTIONS. THE TEXAS HIGHWAY DEPARTMENT IN RESEARCH PROJECT 1-8-63-46 HAS GATHERED IN EXCESS OF 15,000 MEASUREMENTS OF DEFLECTION, RADIUS OF CURVATURE, CRACK WIDTH, AND TEMPERATURE ON CONTINUOUS PAVEMENTS LOCATED THROUGHOUT THE STATE. COMPARISONS OF THE FIELD DATA WITH THE ANALYTICAL RESULTS INDICATE THAT: (1) THE SLAB ANALYSIS TECHNIQUES ACCURATELY PREDICT DEFLECTIONS AS COMPARED TO THE BENKELMAN BEAM, (2) BASIN BEAM MEASUREMENTS INDICATE AN AVERAGE MOMENT WHICH CORRELATES FAIRLY WELL WITH COMPUTED MOMENTS, (3) THE MOMENTS INDICATED BY THE BASIN BEAM ARE SOMEWHAT SMALLER IN MAGNITUDE THAN COMPUTED BY THE FINITE ELEMENT METHOD. /AUTHOR/
