Valorization of local materials on the motorway serving the Port Tangier Med

During the development of the project of the motorway serving the Port Tangier Med, one of the principal constraints that the persons in charge for this project asserted themselves is the attenuation of its environmental impact. Thus, a series of actions was undertaken to achieve this goal, of which the most important is the valorization of local materials for the construction of the Higher Part of Earthworks (PST) of the motorway platform. For this project, the remoteness of locations able to provide noble materials incited the managers to think of an alternative solution more ecological than the basic solution which consists of opening a new quarry, to extract a considerable quantity of materials (approximately 800.000 m3), and then transfer it 50 km. The solution adopted to avoid nuisances with the ecosystem is the use of the marl extracted from the project spoil, which should normally be rejected, and to re-use it for the construction of the PST. This is done with the help of a lime treatment which allows the improvement of the characteristics of this material, which are initially non-reusable. In addition to the easily perceptible impact of this solution on the environment, it made it possible to reduce the cost of the project.
