New Earth Road Degradation Characterisation and Assessment Approach

This article proposes a method for effective and efficient programming of road maintenance works. Based on the usual methods of the Organization for Economic Cooperation and Development (OECD) and of the Laboratoire Centrale des Ponts et Chaussées (LCPC), the approach in this paper covers a wider spectrum of measurable parameters to describe the six (6) degradations most frequent on earth roads in Cameroon. They include: corrugations, ruts, potholes, gullies, loss of materials and loss of camber. Each one of them has been described through the following measurable parameters: length (L), width (l), depth (p), number (n) and size (s). This approach makes use of simple tools and reveals the importance of parameters not taken into consideration in the above-mentioned methods. It will permit a global assessment of the pavement and an objective evaluation of works quantities. The appreciation of road users through investigations on the road quality permitted to fix limits (boundary-marks) parameters, what will drive to the development of a decision matrix, permitting a better maintenance work programming Survey findings have enabled us to validate this method which is similar to the OECD method of degradation assessment.
