NORTH DAKOTA ROUGHOMETER STUDY

NINE YEARS OF EXPERIMENTAL USE OF THE ROUGHOMETER HAVE SHOWN THAT PAVEMENT ROUGHNESS IN NORTH DAKOTA IS NOT A RELIABLE INDICATION OF ITS SERVICEABILITY AND THAT ROUGHNESS TRENDS HAVE LITTLE OR NO VALUE IN PREDICTING ROAD LIFE OR JUDGING PAVEMENT PERFORMANCE. THE CONCLUSIONS DRAWN FROM NORTH DAKOTAS EXPERIENCE WITH THE ROUGHOMETER ARE AS FOLLOWS ' /1/ FOR THE TYPE OF ASPHALT OR BITUMINOUS PAVEMENTS GENERALLY USED IN NORTH DAKOTA, THE ROUGHOMETER DOES NOT GIVE A MEANINGFUL MEASURE OF CONDITION OR SERVICEABILITY, /2/ IRRESPECTIVE OF CORRELATION WITH SERVICEABILITY, ROUGHNESS TRENDS OF THE STUDY TEST SECTIONS LACK THE UNIFORMITY THAT WOULD BE NEEDED FOR THEIR USE IN PREDICTING ROAD LIFE, /3/ THE USE OF ROUGHNESS TRENDS IN ANY STUDIES OF PAVEMENT PERFORMANCE IN NORTH DAKOTA IS RENDERED IMPRACTICAL BY THE EFFECT OF ENVIRONMENT, MAINTENANCE AND THE VARIETIES OF SURFACE TEXTURE, AND /4/ RIGID PAVEMENTS IN NORTH DAKOTA DO NOT AT THE PRESENT TIME FORM A SUITABLE SAMPLE FOR ROUGHOMETER STUDY. THE PAVEMENTS OF THIS TYPE NOT SCHEDULED FOR EARLY RECONSTRUCTION ARE ALL RELATIVELY NEW AND HAVE NOT YET SHOWN DETERIORATION MEASURABLE BY THE ROUGHOMETER. /AUTHOR/
