Title: THE DEVELOPMENT AND USE OF A PAVEMENT MANAGEMENT SYSTEM IN THE UK --PROCEEDINGS OF THE FIFTH INTERNATIONAL CONFERENCE ON THE STRUCTURAL DESIGN OF ASPHALT PAVEMENTS HELD DEFLT UNIVERSITY OF TECHNOLOGY, AUGUST 23-26 1982. VOL 1 AND 2. -- NETHERLANDS
Abstract: In 1970, the committee on highway maintenance, set up by the UK Ministry of Transport reported on all aspects of highway maintenance including standards, engineering, management, training and many others. For the management of maintenance it recommended the development of a maintenance assessment system which led to the system produced by the transport and Road Research Laboratory (TRRL), computerised highway assessment of ratings and treatments (chart). The chart system embraces inspection, rating, computer processing and the output of information which can be in several different forms. In addition to the collection of chart visual information, the overall management system encompasses mechanical measurements for the assessment of structural condition (deflection), of skidding resistance (SCRIM) and texture measurement and of road profile. The use of the bump integrator and of the high-speed profilometer (hsp) for profile measurement is described. The paper deals with the development of the chart system and its various components as well as illustrating the way in which the rating is carried out by the computer. The various items of mechanical equipment are also described and illustrated. The rating system is complicated and varies depending on the defect being rated. For interpretation of the priorities for structural treatment, a number of ratings are combined. Although it is not possible to comment on the range of ratings computed, an illustration is given to show how the results are interpreted and the priorities assessed. A variation of the assessment system output is used by the greater London council in the management of the capital's major road network. For the mechanical measurements and accident records, transparent overlays are produced which can be placed on a map of the network. In this way, the engineer can quickly assess those sites in need of his attention. Finally, some innovations are referred to which are being developed in the course of the continual enhancement of the system.(a) for the covering abstract of the conference see IRRD 815640.
