IN 1940 THE KENTUCKY DEPARTMENT OF HIGHWAYS CONSTRUCTED AN INVESTIGATIONAL CONCRETE PAVEMENT. THE 6.27-MI PROJECT WAS CONSTRUCTED TO STUDY AND EVALUATE THE PERFORMANCE OF SUCH PAVEMENTS OVER A PERIOD OF YEARS. THE PRESENT REPORT IS A 17-YEAR PERFORMANCE SURVEY WHICH INCLUDES DATA OBTAINED ON THE PROJECT THROUGH 1958. SUBGRADE, TRAFFIC, RIDING QUALITY, AND OVER-ALL CONDITION DATA ARE PROVIDED. ON THE WHOLE, THE PAVEMENT OF UNIFORM 7-IN CROSS-SECTION HAD THE POOREST PERFORMANCE RECORD OF ALL THE PAVEMENT IN THE PROJECT. OF THE OTHER SECTIONS, WHICH ARE ALL OF 9-7-9-IN CROSS-SECTION, THE PAVEMENT WITH ALTERNATING EXPANSION AND CONTRACTION JOINTS EVERY 60 FT AND WITH 70 LB OF REINFORCEMENT HAD THE POOREST PERFORMANCE RECORD. THE RESULTS OBTAINED FROM THIS PROJECT, REPRESENTING SPECIFIC AGGREGATE AND SPECIFIC CONSTRUCTION METHODS, PERMIT THE FOLLOWING IMPORTANT CONCLUSIONS: (1) EXPANSION JOINTS MORE THAN 400 FT APART ARE OF LITTLE BENEFIT AND ARE PROBABLY DETRIMENTAL. (2) CONTRACTION JOINTS, FOR BEST PERFORMANCE, SHOULD BE CLOSELY SPACED (20 TO 30 FT APART). (3) DOWEL BARS FOR LOAD TRANSFER AT CONTRACTION JOINTS ARE OF QUESTIONABLE VALUE EXCEPT IN THE CASE OF JOINTS THAT OPEN CONSIDERABLY AND REMAIN OPEN, THUS BEING DEPRIVED OF ANY ADVANTAGE THAT MIGHT BE GAINED THROUGH INTERFACIAL PRESSURE AND AGGREGATE INTERLOCK. (4) THE THICKENED EDGE PAVEMENT SECTION IS SUPERIOR TO THAT OF UNIFORM 7-IN. THICKNESS. /AUTHOR/
