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

FINISHED PAVEMENT MUST NOT ONLY BE SMOOTH RIDING BUT MUST ALSO BE DURABLE, STRUCTURALLY SOUND, AND SAFE (PROVIDE AMPLE SKID RESISTANCE). TO THIS END, A STUDY WAS CONDUCTED TO DEVELOP IMPROVED CONSTRUCTION PRACTICES RELATED TO THE CONSOLIDATION, FINISHING, AND CURING OF CONTINUOSULY REINFORCED CONCRETE PAVEMENTS (CRCP). A TOTAL OF 56 SIDEWAL SIZE SLABS WERE CAST IN CONTROLLED ENVIRONMENTAL ROOMS. PARAMENTERS INVESTIGATED INCLUDED TYPES 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. THE CORES WERE THE SUBJECT 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.
