This article proposes a method for effective and efficient programming ofroad maintenance works. Based on the usual methods of the Organisation for Economic Co-operation and Development (OECD) and of the Laboratoire Centrale des Ponts et Chaussees (LCPC), the approach used 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, width, depth, number and size. This approach makes use of simple tools and revealsthe importance of parameters not taken into consideration in the above-mentioned methods. It will permit a global assessment of the pavement and anobjective evaluation of the quantity of work required. The appreciation of road users through investigations on the road quality enabled the fixingof limits (boundary-marks) parameters, what will drive to the developmentof a decision matrix, permitting a better maintenance work programming. Survey findings have enabled the validation of this method which is similarto the OECD method of degradation assessment. For the covering abstract see ITRD E139491.
