THE PCA ROAD METER IN WASHINGTON'S PAVEMENT CONDITION SURVEY SYSTEM

SINCE THE INTRODUCTION OF THE PRESENT SYSTEM FOR PERFORMING PAVEMENT CONDITION SURVEYS ON WASHINGTON HIGHWAYS FOR PRIORITY PROGRAMMING, THERE HAVE BEEN RESERVATIONS AS TO THE SUBJECTIVITY OF THE METHOD. THAT PART OF THE SYSTEM WHICH EVALUATED THE RIDEABILITY OF A PAVEMENT HAS BEEN OF GREATEST CONCERN. THE DEVELOPMENT OF THE PCA ROAD METER APPEARED TO OFFER A MEANS OF INTRODUCING AN OBJECTIVE MEASURE OF PAVEMENT SMOOTHNESS INTO THE RATING SYSTEM. TO THAT END THE ROAD METER WAS EVALUATED. MODIFICATIONS WERE INTRODUCED, THE 7000 MILES WERE EVALUATED BOTH SUBJECTIVELY AND WITH THE MODIFIED ROAD METER, AND FORMULAS WERE DEVELOPED TO INTRODUCE ROAD METER RESULTS INTO THE PAVEMENT CONDITION RATING SYSTEM. /AUTHOR/
