This API provides access to a geolocated layer of surveys carried out on road pavement (enrobés) prior to roadworks within Rennes Métropole. Each survey point indicates whether asbestos is present and whether polycyclic aromatic hydrocarbons (PAH) occur at elevated concentrations in the pavement material. The dataset is published by Rennes Métropole and supports risk assessment and planning ahead of road construction or maintenance projects, helping identify sites requiring specific handling procedures for hazardous materials before excavation or resurfacing work begins.Cette couche permet de localiser les sondages réalisés sur les enrobés de voirie en amont du démarrage des chantiers de travaux sur voirie. Ces sondages permettent de repérer la présence (ou non) d'amiante ainsi que la présence (ou non) d'HAP (Hydrocarbures Aromatiques Polycycliques) en teneur él...
