Abstract
Among the many innovations developed in France in the field of road maintenance, three in particular may significantly improve users' and maintenance workers' safety: (a) the cone dispenser, which automatically and rapidly sets up and removes one or two rows of warning cones; (b) the mobile lane separator which can place road marker blocks that are similar to the New Jersey type of barrier at either 12 or 30 km/hr; and (c) the G810 road surface marking lorry for road surface line painting using several new techniques that improve productivity as well as personnel and traffic safety. These machines and their advantages are discussed.
