Bituminous pavements require considerable financial resources, as does their maintenance. Many of the world's countries, particularly those in the Third World, are faced with economic difficulties that make it impossible for them to maintain their pavements in good time, or to build a new pavement in the event of major deterioration. The study carried out in this document is based on the cracks that threaten bituminous pavements, with the aim of diagnosing all the probable causes of these cracks and proposing technical rehabilitation solutions to ensure the comfort and safety of users. This work is divided into two parts, the first of which is devoted to a bibliographical study of the various degradations of bituminous pavements, followed by an in-depth study of the cracks in bituminous pavements and the solutions envisaged for treating them. The second part begins with an overview of the new techniques for preventing the re-emergence of cracks as an excellent solution for preventing the propagation of cracks.
