Abstract
Road pavement constructed with fibremix concrete allows longer distances between joints compared to unreinforced concrete pavements. Fibremix concrete has been used in parking areas near motorways, city roundabouts, road crossings, bicycle paths and regional roads with uncracked lengths up to 80 m. Without a dedicated design tool for fibremix concrete pavements, the maximum crack-free slab length was obtained by trial and error during several projects. In 2015, with the experience from the past years, the Province of Noord-Brabant, a regional government in the Netherlands, has constructed a roundabout in fibremix concrete on a crossing between two regional roads. This paper describes the design, special details and execution of this roundabout in fibremix concrete. Some technical details of the roundabout: T-crossing on the N625 near the city of Oss, the Netherlands One single-lane roundabout: pavement width: 5.25 m Diameter: 50 m Thickness of concrete pavement: 25 cm Fibremix concrete (2 types of steel fibres + 1 type of polypropylene fibre) Only 6 doweled joints Note: the roundabout was designed and constructed by the Den Ouden Group in the period May – June 2015.
