Concrete in Roundabout Design

Paper by MAHDALOVA KRIVDA from ISCR 12th 2014 Prague Czech Republic

The paper describes the actual possibilities of using concrete pavement in a roundabout. Concrete may be better material for aprons than conventional cobblestones. It can be better for both durability of the road and for road safety. If heavy vehicles often pass through the cobblestone pavement in the apron, the cobbles can eventually move out of their position. These loose cobbles could then become dangerous for traffic and can cause an accident. Concrete is now also recommended instead of asphalt for circulatory roadways because concrete resists better under a high traffic load and the surface does not require frequent repairs. This paper presents the current knowledge of this practice, particularly in the Czech Republic.
