CONTINUOUSLY REINFORCED CONCRETE PAVEMENT OBSERVATION PROGRAM IN MISSISSIPPI - A PROGRESS REPORT

THIS REPORT COVERS THE SECOND YEAR OF A 5-YEAR OBSERVATION STUDY OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENT CONSTRUCTION IN MISSISSIPPI. MEASUREMENTS FROM THE DESOTO COUNTY AND JONES COUNTY EXPERIMENTAL PROJECTS CONSTRUCTED IN 1961 AND 1962 WERE CONTINUED. THEIR DESIGN FEATURES, DATA ON END MOVEMENT, CRACK WIDTH, AND CRACK FREQUENCY, ARE PRESENTED AND DISCUSSED. A PRELIMINARY REVIEW OF THE DESIGN AND CONSTRUCTION STATISTICS AND THE STATEWIDE CRACK SURVEY OF ALL COMPLETED PROJECTS WAS MADE. THIS REVIEW INDICATES THAT IN MISSISSIPPI THE POURING TEMPERATURES AND THE DESIGN AVERAGE DAILY TRAFFIC ARE NOT THE MAJOR FACTORS INFLUENCING CRACK SPACING. AFTER THE EARLY YEARS OF SERVICE, AGE OF THE PAVEMENT DOES NOT APPEAR TO BE AN IMPORTANT FACTOR IN CRACK SPACING. THE FAILURE INVESTIGATIONS AND REPAIR PROCEDURES ARE ALSO REPORTED. FAILURES, WHICH REPRESENT A VERY SMALL AND INSIGNIFICANT PERCENTAGE OF THE TOTAL COMPLETED MILEAGE, WERE STUDIED SO THAT THEIR CAUSES COULD BE CORRECTED IN FUTURE PROJECTS. REPAIR PROCEDURES WERE OBSERVED IN THE HOPE THAT A STANDARD MAINTENANCE PROCEDURE COULD BE ESTABLISHED AT THE END OF THE STUDY. /AUTHOR/
