PAVEMENT ROUGHNESS AND SERVICEABILITY

THE PENNSYLVANIA DEPARTMENT OF TRANSPORTATION, THROUGH THE PAVEMENT EVALUATION SECTION IN THE BUREAU OF MATERIALS, TESTING AND RESEARCH, HAS BEEN DOING RESEARCH SINCE 1968 IN THE FIELD OF PAVEMENT ROUGHNESS TRENDS. THIS INTERIM REPORT CONCERNS THE PROGRAM PROCEDURES AND A DISCUSSION OF THE TEST RESULTS FOR THE 1971 PROGRAM. THE RESEARCH IS CONCERNED WITH CARRVING OUT A PERIODIC PROGRAM OF PAVEMENT ROUGHNESS MEASUREMENTS IN ORDER THAT A PREDICTION CAN BE MADE AS TO THE SERVICEABILITY OF ANY GIVEN SECTION OF PAVEMENT PRIOR TO THE NEED FOR REHABILITATION. A COMPREHENSIVE TESTING PROGRAM TO INVENTORY THE ENTIRE STATE HIGHWAY SYSTEM WAS INITIATED IN THE SPRING OF 1968 AND IS CONTINUING ON AN ANNUAL BASIS. THE INITIAL ROUGHNESS MEASUREMENTS ON NEW CONSTRUCTION WITH SUBSEQUENT RE-TESTS OF THIS CONSTRUCTION WILL PERMIT THE DEVELOPMENT OF A SERVICEABILITY CURVE FOR USE IN PREDICTING THE SERVICEABILITY OF A PAVEMENT SURFACE WITH A KNOWN INITIAL ROUGHNESS FACTOR.
