Abstract

Tasmania's Department of Infrastructure, Energy and Resources (DIER) has recently produced its strategic road asset management plan and is developing its capability to employ the HDM-4 road investment tool to enhance existing pavement management systems. As part of the input to the development of their strategic plan, DIER engaged ARRB to configure and calibrate HDM-4 and to apply it in a strategic analysis of long term budget needs and performance trends. Whilst the outcome of the project was considered valuable, it was understood that certain aspects of the analysis were based on assumptions related to typical surfacing lives and the associated deterioration and works effects models. In order to improve the basis for the analysis, further studies were undertaken to investigate improved surface performance predictions and treatment strategies; improved works effects models; migration of the current HDM-4 V1.3 analyses to the newly released HDM-4 version 2.0 and the suitability of the asset valuation procedures in HDM-4 to assist DIER with conducting its annual valuations. This paper describes the results of the studies and their implications for long term strategic planning of road assets in Tasmania.
