Pavement management faces three major hurdles when a decision has to be made as to why, how and when to intervene. There are the issue of growing data volumes, which makes the interpretation even more difficult, the reliability of diagnosis of road deterioration causes, and the recognition of environmental impacts on equal grounds as the technical and the economic concerns. Conventional pavement management systems are not suited to integrate all three concerns, which in turn leads to inadequate strategic choices and consequently poor investments.
It is paramount that the right diagnosis is pointed out reliably and it is equally important that polluting emissions, from road traffic, are monetized. The integration of environmental costs in the economic analysis is essential to select the optimal road intervention strategy. Finally, the widely used rigid framework of databases and reports is reviewed in favour of new graphical based information technologies.
In this context, the main objective of this thesis is to improve the decision-making process in order to reflect on better road management. Firstly, the thesis assesses and monetizes the environmental impacts of different strategies. Secondly, the thesis provides a graphic and digital platform that compiles the technical, economic and environmental parameters on one multiple ordinate chart.
The thesis applies these findings on a test case in a West African country, and shows how human health and the well-being of the environment can be taken into account. This project constitutes a positive step toward greater involvement of the road sector in the sustainable development.
