The road network manager constantly needs information on the condition of paved roads in order to properly plan maintenance and renewal. The ideal would be to have a reliable model of the condition of the network and its degree of service. This work intends to build a road network model for Togo based on a characterization of the paved roads and prevailing climatic conditions. The characterization of the condition of the roads in their environment was based on extensive documentation and field surveys. The paved national Togolese road network supports heterogeneous class of T5 to T0 traffic, dominated by untreated bedrock structures (84.41%) mostly coated with asphaltic concrete (78.47%). The early onset of degradation, mainly of small amplitude, on the surface of the pavements is explained by the use of pavement materials without considering the diversity of traffic or climatic factors.
