Circular edge segment assembly for forming mini roundabout, comprises segments with corresponding male and female profiles at opposite ends

摘要

The segments (1, 6, 8) are made from concrete and have a male profile (3, 7) at one end and a corresponding female cavity (5) at the other end, so that the male profile can be engaged with a female cavity in an adjoining segment and so that radial displacement of adjoining segments relative to each other is prevented. The segments can be joined together to form a circle, in which each segment contributes to at least 30% of the length of the circle radius. An Independent claim is also included for a method for laying a mini roundabout using this assembly.
