USING CONCRETE BLOCKS IN CARRIAGEWAYS AT BUS STOPS

Wheel rutting is a problem prevalent in urban areas around bus stops. The London borough of Hackney is testing an area that had rutted to a depth of 40 mm using a method developed by the Cement and Concrete Association. An area 3 M by 70 M has been constructed using precast 80 mm bevelled interlocking blocks laid in a herringbone pattern on an 80 mm layer of sharp sand. The article describes the method used to lay the blocks ensuring that lateral restraint was maintained. The finished level was designed to be 10 mm proud to allow for any settlement on the outside edge and provide a channel for surface water on the inside edge. One mason and two labourers were able to lay 130 square metres per day. Well coordinated deliveries are essential on sites in the London area. The cost of providing this stable construction is hoped to be compatible with that of conventional flexible material. /TRRL/
