Boskalis is working on an extension of the A5 motorway in the Amsterdam area. One of the site roads had been surfaced with a layer of mixed granulate.
“In wet weather, the tyres destroy the surface, turning it into a slushy mud that offers little grip and no support for the vehicle.” We are talking to Marco Horden, who, along with his colleagues, reported this problem to the site foreman on several occasions. When the thaw set in in January and the situation worsened, Marco called general site foreman Walter van de Reep and told him that it was no longer safe to drive in these conditions. A crane was used to remove the turf from an adjacent embankment on the very same day and the drivers switched to this alternative route.
