Abstract: The present application relates to a method and apparatus for manufacturing an agglomeration of glass beads consisting of a plurality of glass beads bound together by means of a binder material. An apparatus is described which includes a dispensing device (3a; 3b; 3c) having a plurality of channels (5) along which, in use, binder material flows. Each of the channels terminates in an outlet (8) and is in fluid communications with a single binder inlet (6). Importantly, the channels are of substantially identical length and diameter.

Abstract: The present application relates to methods for laying a traffic calming surface, in which molten material is deposited on the surface of a road or path and is then moulded so as to form a continuous, substantially sinusoidal profile which extends along the intended direction of travel. The profile can be formed by employing at least one pair of longitudinal rails which are positioned on the surface of the road so as to be spaced apart from each other and such that they are aligned with the intended direction of travel. The upper surface of the rails exhibits the required profile so that molten material deposited between the rails can be spread between the rails to form the required surface.
