Abstract: Road safety is a fundamental issue for developing countries, given its impact on the economic and social development of the country, thus ensuring the safety of users and goods. The goal of this approach is to create resilient pavement design and maintenance strategies that effectively tackle the challenges posed by fluctuating load conditions and temperature variations. This analysis is based on a case study of a road section subjected to mechanical loads that are modeled and studied in order to analyse the effectiveness of the current design of road pavements in relation to deformation resistance. On this, it is possible to create an effective design strategy in relation to the possible challenges. In this study, the Boussinesq model is selected to be studied as an example of an elastic model. It is carried out with the aim of initiating the establishment of a Moroccan Pavement Management System based on models predicting roadway performance. This System aims to ensure road safety and prevent issues such as rutting, cracking, and a shortened pavement lifespan. By modeling the stresses and deformations for each type of traffic using the Boussinesq model, the impact of cumulative loading and time variation turns out to be significant. A flexible pavement under TPL4 or TPL5 type traffic appears, according to the results of the present study, to have good homogeneity and performance characteristics in relation to loading, whereas a flexible pavement subjected to TPL6 type traffic, requires special attention, especially in relation to high temperatures. Indeed, a cumulative loading over ten years will lead to a deterioration of the road structure. Special attention should be paid to the hottest areas when designing for the temperature variation.
