Résumé

The paper attempts to model the parameters of recurring degradations on dirt roads, then the development of the matrix known as “matrix of decision” in order to facilitate the implementation of a decision-making system for road maintenance. These matrices are used as an input in the function of decision which will be studied thereafter. We suggest a solution based on a general knowledge of these degradations, then a restriction on a finite number of relevant parameters. The approach is based on the method of the OECD of which the interest is the use of simple tools easily available in the Developing Countries. We take into account in this work parameters such as: the distance between the ridges of corrugation, the width of the gullies and the rutting and the area of the potholes, which were neglected by OECD but which are relevant. The results obtained will make it possible to improve OECD method used so far.
