Development and Implementation of an Asset Management System for Pavements and Bridges
This paper presents a common framework for the optimization of maintenance strategies for existing pavements and bridges. For both infrastructure assets, performance is defined in terms of a condition index that is associated with visual inspections. A set of maintenance actions is defined for each infrastructure, considering common practice in Europe. Optimization using Genetic Algorithms is carried out to find the best possible balance between cost and performance. This framework will allow more consistent and economically sound decisions at both a national and a local level. The framework, in the pavement’s component, uses the deterministic pavement performance model of the AASHTO flexible pavement design method. The quality of road pavements is evaluated by the PSI, which is computed by using a modified version of the PSI AASHTO equation. The framework, in the bridge’s component, considers a probabilistic condition index defined by the cracked area of deck, based on experimental data gathered in the Netherlands. The framework, applied to a road network considered as a case study, presented good results. The final part of the paper contains a reflection on the main difficulties encountered so far and presents the developments planned for the near future.
