BRIDGE DECK STUDY FINAL REPORT

THIS REPORT PRESENTS RESULTS OF A STUDY ON FACTORS CAUSING ROUGHNESS OF CONCRETE BRIDGE DECKS IN SOUTH DAKOTA. FIELD OBSERVATIONS WERE MADE ON 47 BRIDGES CONSTRUCTED DURING 1964 AND 1965. DATA WAS OBTAINED RELATING TO DESIGN, CONTRACTING ORGANIZATION, TYPE OF FALSE-WORK, FINISHING EQUIPMENT, WORK METHODS, CONTRACTOR PERSONNEL, MATERIAL TEST RESULTS, WEATHER CONDITIONS AND OTHER FACTORS BELIEVED TO AFFECT ROUGHNESS. THESE DATA WERE SUPPLEMENTED BY MANY PHOTOGRAPHS. DURING 1965, COMPLETED BRIDGE DECKS WERE EVALUATED FOR ROUGHNESS. ATTEMPTS TO USE MECHANICAL MEASURING DEVICES WERE NOT SUCCESSFUL. A PROCEDURE WAS DEVELOPED INVOLVING SUBJECTIVE RATINGS OF RIDING QUALITY, TEXTURE AND APPEARANCE PLUS MEASUREMENT OF AREAS WHICH HAD BEEN PATCHED OR GROUND DURING CONSTRUCTION. RESULTS OF THE RATINGS ARE PRESENTED AND RELATED TO BRIDGE DESIGN, TYPE OF FINISHING EQUIPMENT, WEATHER CONDITIONS, AND CONTRACTING ORGANIZATION. THE MAJOR IMPORT OF CONCLUSIONS WAS THAT ALL OF THE COMMERCIALLY AVAILABLE FINISHING EQUIPMENT WAS CAPABLE OF PRODUCING SMOOTH DECKS, THAT SHORT SPAN LENGTHS WERE CONDUCIVE TO ROUGHNESS AND THAT THE CONTRACTING ORGANIZATIONS SKILL WAS THE MOST IMPORTANT SINGLE FACTOR. /BPR/
