STRENGTHENING OVERLAY DESIGN AS ROUTINE PROCEDURE, A CRUCIAL STAR IN THE PMS IMPLEMENTATION . THIRD INTERNATIONAL CONFERENCE ON BEARING CAPACITY OF ROADS AND AIRFIELDS. PROCEEDINGS, NORWEGIAN INSTITUTE OF TECHNOLOGY, TRONDHEIM, NORWAY, JULY 3-5 1990. VOLUMES 1-2

This paper describes the implementation of the Danish Pavement Management System (PMS) from a pilot project to a nationwide system. This was only possible through extensive collaboration between the Road Directorate, National Road Laboratory and the Technical Administrations of the countries. As foreseen, the introduction of strengthening overlay design as a routine procedure became a crucial part of the implementation. 15000 falling weight deflectometer (FWD) tests were performed, to collect the required bearing capacity data. 4000 trial pits were excavated, to measure accurately the layer thicknesses at the analysis test points. 4000 FWD test results were backcalculated for assessment of pavement E-moduli and needs for strengthening. The successful acquisition of the bearing capacity data was ensured by stepwise implementation of the PMS, starting with those parts of the Danish road network that most urgently needed attention. Available resources did not allow implementation of the whole road network in one step. Close reference lines, extensive information for all participants, and follow-up meetings during the implementation gave good motivation and high quality of work. 10 rules for successful implementation are given.
