  • Study of the Impact on Surface Water of Lime Slurry Used to Treat Bleeding

    Bleeding is a phenomenon that usually occurs during periods of intense heat, mainly on roads coated with thin surfaces, such as surface dressings (SD). A surface dressing is a treatment consisting of successive layers of binder and aggregates. Bleeding is when bitumen rises from the thin layer to the surface. This phenomenon is exacerbated by hot summer weather and by the level of traffic constraints. When bitumen becomes viscous or even liquid, it is no longer able to ensure maintenance of the [...]

  • PIARC Prize - Organization and Administration - Identifying and Resolving the Problems of Accessibility to Basic Services Experienced by Rural Communities through the Integrated Rural Accessibility Planning (IRAP) System

    IRAP is a participatory local planning method (developed by the International Labour Organization) based on the concept of rural accessibility. This is understood to mean how easy or difficult it is for rural communities to use, access or obtain basic goods and services. Accessibility is an important factor in rural development and therefore perceived as one of the main factors in poverty, especially in rural areas of developing countries.
