  • Impact of Earthworks on the Quality of Unpaved Roads in Côte d’Ivoire

    Earthen roads, in the general sense, make up over 90% of the road network in Côte d’Ivoire (AGEROUTE CI, 2024), as in most West African countries. Although these roads typically carry low traffic volumes, they play a crucial role in opening up rural areas and transporting agricultural products. As such, their socio-economic importance should not be underestimated.

  • Reasons of the D47 Motorway Pavement Deformations Caused by Swelling of Metallurgical By-Products

    Metallurgical by-products, primarily blast furnace and steel slag, have ranked among important alternative sources of fill as well as of material for the structural layers in highways. These are always artificial aggregates produced within the ironmaking or steelmaking process, or in the production of nonferrous metals.
