OBSERVATION AND ANALYSIS OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS

THE USE IS DESCRIBED OF THE BENKELMAN BEAM AND THE CURVATURE (BASIN) BEAM ON TEST SECTIONS OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS (CRCP) WHICH WERE EXAMINED IN A PREVIOUS STATEWIDE SURVEY OF TEXAS PAVEMENTS. FIELD DATA AND ASSOCIATED ASSUMPTIONS ARE COMPARED WITH THE RESULTS OF A NUMERICAL ANALYSIS SOLUTION OF A FINITE ELEMENT MODEL OF A SLAB. THE MODEL WAS THAT DERIVED BY STELZER AND HUDSON IN A DIRECT COMPUTER SOLUTION FOR SLABS ON FOUNDATIONS (ACI JOURNAL, V. 65, NO. 3, MARCH 1968). THE FINDINGS SHOWED GOOD CORRELATIONS BETWEEN QUANTITIES DERIVED FROM FILED MEASUREMENTS AND THOSE CALCULATED. QUANTITIES COMPARED WERE DEFLECTIONS, RADIUS OF CURVATURE, AND MOMENTS. OVERALL CONCLUSIONS WERE THAT THE MODEL ANALYSIS IS REASONABLY RELIABLE BUT THE CALCULATED MOMENTS IN THE SLAB ARE SYSTEMATICALLY GREATER THAN THOSE PREDICTED BY THE BASIN BEAMS. /AUTHOR/
