MEASUREMENT OF PAVEMENT ROUGHNESS AND THE USE OF SUCH MEASUREMENTS IN THE EVALUATION OF CONSTRUCTION PROCEDURES AND PAVEMENT PERFORMANCE

THE REPORT COVERS THE UNIVERSITY OF TENNESSEES EXPERIENCE IN MAKING THE BPR-TYPE ROUGHOMETER FIELD OPERATIONAL AND SUBSEQUENT STUDIES ON THE TENNESSEE HIGHWAY SYSTEM. THIS COVERAGE INCLUDES /1/ GENERAL LEVEL OF ROAD ROUGHNESS OF THE INTERSTATE AND PRIMARY HIGHWAYS, /2/ THE LEVEL OF ROAD ROUGHNESS FOR NEWLY CONSTRUCTED FLEXIBLE PAVEMENT, /3/ THE LEVEL OF ROUGHNESS OF BRIDGE DECKS AND ADJACENT PAVEMENTS, AND /4/ MINOR STUDIES COMPARING ROAD ROUGHNESS WITH DEFLECTION MEASUREMENTS AND SKID RESISTANCE. THE REPORT CONCLUDES' /1/ THE GENERAL LEVEL OF ROAD ROUGHNESS FOR THE TENNESSEE PORTION OF THE INTERSTATE SYSTEM SHOWED 65% OF THE RIGID PAVEMENT TO BE VERY SMOOTH OR SMOOTH AND 33% TO BE SLIGHTLY ROUGH. THESE PERCENTAGES FOR THE FLEXIBLE PAVEMENTS WERE 78 AND 22% RESPECTIVELY. /2/ THE AVERAGE BRIDGE DECK ROUGHNESS WAS 140-INCHES PER MILE WHILE THE ADJACENT PAVEMENTS AVERAGED 86.8-INCHES PER MILE. /3/ A MORE REPRESENTATIVE SAMPLE OF ROAD ROUGHNESS IS OBTAINED IF THE ENTIRE PROJECT IS EVALUATED IN PREFERENCE TO SELECTED SHORT SECTIONS. /4/ BASED ON LIMITED TESTS, SOME CORRELATION WAS FOUND BETWEEN ROAD ROUGHNESS AND SKID RESISTANCE. /5/ LITTLE CORRELATION WAS FOUND BETWEEN THE PARAMETERS MEASURED BY THE BENKELMAN BEAM AND THE ROUGHOMETER. /BPR/
