CONCRETE ROAD BARRIERS FOR INCREASED TRAFFIC SAFETY

BETONLEITWAENDE FUER DIE ERHOEHTE VERKEHRSSICHERHEIT

The steel crash barriers which are used in Germany to a great extent reduce the force of the impact by their deformation, but after each accident large scale repair or replacement is necessary. Concrete barriers, which have already found widespread use in the USA, France, Belgium and England, perform the same function as steel barriers. The barriers are 80 cm high (not including the foundation) and the width is 15 cm at the top, 25 cm at a height of 33 cm and 61 cm at the bottom. They are cast with slip forms using ready-mixed concrete or are constructed from precast units set in place with a mobile crane and connected together and to the foundation with dowel bars. Vehicles have up to now not been able to drive across these barriers; impacting vehicles are guided back onto the carriageway. Any damage can be easily repaired. Some impact tests are discussed. Figures are quoted for reduction of accidents. It is also stressed that the wall height of 80 cm prevents dazzle. (TRRL)
