<p>A marker for insertion into a road surface has a domed top (2) and a base part (1) with side walls (9) depending from a flange which will be set flush into the road surface. Keyway cut-outs (7) extend vertically in the outer face of the base part which acts to receive a suitable mastic provided in the hole receiving the mounting, to help to hold the mounting rigidly in place. A circumferential groove (8) provides additional keying of the mounting. The top incorporates either cavities (4) for the receipt of reflectors, or grooves (not shown) to receive or define coded marking strips. Centrally of the domed surface is a cruciform keyed recess (6) which will receive a similarly shaped fitting at the end of a fixing tool for enabling the mounting to be rotated. <IMAGE></p> |
