LABORATORY STUDY OF EFFECTS OF ENVIRONMENT AND CONSTRUCTION PROCEDURES ON CONCRETE PAVEMENT SURFACES

A STUDY WAS CONDUCTED TO DEVELOP IMPROVED CONSTRUCTION PRACTICES RELATED TO THE CONSOLIDATION, FINISHING, AND CURING OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS (CRCP). A TOTAL OF 56 SIDEWALK SIZE SLABS WERE CAST IN CONTROLLED ENVIRONMENTAL ROOMS. PARAMETERS INVESTIGATED INCLUDED TYPE OF SUBBASE, METHOD OF CONSOLIDATION (VIBRATION), TYPE OF FINISH, TYPE OF CURING METHOD, AND CURING ENVIRONMENT. ALSO, THE SLABS WERE UTILIZED TO DETERMINE THE EFFECTS OF WIND ON THE EVAPORATION RATE OF WATER FROM THE SURFACE OF THE SLABS. THIS WAS ACCOMPLISHED BY GENERATING WIND OVER THE SURFACE OF THE SLABS. AFTER A 28 DAY CURING PERIOD THE SLABS WERE REMOVED FROM THEIR CURING ENVIRONMENT AND A MINIMUM OF THREE CORES WERE TAKEN FROM EACH. THESE CORES WERE THEN SUBJECTED TO DIAGNOSTIC ANALYSES. AT THE CONCLUSION OF THE TESTS, THE DATA TAKEN FROM THE CORES ALONG WITH THE WATER LOSS MEASUREMENTS WERE REDUCED, TABULATED, ANALYZED, AND CURVES PLOTTED TO ILLUSTRATE THE RESULTS OBTAINED. /FHWA/
