THE ANALYTICAL-EMPIRICAL METHOD USED IN A PAVEMENT MANAGEMENT SYSTEM. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN

At the Fifth International Conference a paper was presented by Ullidtz & Peattie, outlining how the analytical-empirical method could be used for performance prediction in a Pavement Management System (PMS). This paper presents the development that has taken place since then and that has resulted in a full PMS presently being used for more than 5,000 km of highways in Europe. An essential part of this system is still the analytical-empirical model for performance prediction. This model and some attempts at verification and improvements are described in some detail in a companion paper for this conference. This paper describes the basic elements of the PMS, consisting of: 1) Input data (functional, structural, constraints); 2) Data base ("point" and "section" data bases); 3) Data analysis (spreadsheet reports, benefit/cost, optimization); 4) Output data (predicted future condition, optimum budget); and 5) Implementation (examples of feed back). The system can be operated on a microcomputer. Most of the data (distress, roughness and structural data) are collected using automatic equipment storing the data on disc or tape that can be directly accessed by a microcomputer. The paper describes an efficient optimization procedure that can be used even for large road networks, and provides examples of the use of spreadsheets for data reporting. Finally, some examples are given on the use of PMS data bases for research purposes.
