<p>A tactile stud for incorporation into a paved area has a head 10 with a recess 15 in it's upper surface and a stem 12, which projects downwardly from the central region of the underside of the head 10. Granular material e.g. granite or silicon carbide is bonded into the recess 15 in the head so that the upper surface region of the granular material is just above the material of the head 10 around the recess 15. Granular material 16 may be bonded to a carrier sheet 21 which is die-cut to the shape of the recess and is then bonded therein. The carrier sheet 21 and the adhesive bonding the granular material 16 thereto may be coloured to enhance visibility of the stud. The head and stem may be made of stainless steel, brass, bronze, aluminium or plastic.</p> |
