and, a grip insert attachment system configured to allow releasable attachment of the respective grip insert to the respective grip member, wherein the first aperture is one of a plurality of apertures configured to receive a plurality of respective grip inserts, wherein the plurality of apertures are arranged at different positions along a height of the respective first or second grip member, wherein the respective grip member comprises a grip insert connection portion characterised in that the respective grip insert comprises a grip member connection portion such that the grip insert connection portion and the grip member connection portion co-operate to releasably attach the respective grip insert to said respective first or second grip member (220, 230), wherein the grip insert attachment system comprises: a first socket through the grip insert connection portion; a second socket through the grip member connection portion; and, a removable implement, wherein the removable implement is configured to be reversibly inserted through both the first and second sockets (820-822, 870-873) simultaneously to releasably attach the respective grip insert to said respective first or second grip member (220, 230). first and second grip members (220, 230) for engaging said one or more panels of the temporary roadway, and, an actuation system (216, 218) configured to adjust a separation distance between the first and second grip members (220, 230) for grabbing and releasing said one or more panels of the temporary roadway, wherein one or both of the first and second grip members (220, 230) comprise: a first aperture configured to receive a respective grip insert for frictionally engaging the one or more panels of the temporary roadway; and, a grip insert attachment system configured to allow releasable attachment of the respective grip insert to the respective grip member, wherein the first aperture is one of a plurality of apertures configured to receive a plurality of respective grip inserts, wherein the plurality of apertures are arranged at different positions along a height of the respective first or second grip member, wherein the respective grip member comprises a grip insert connection portion characterised in that the respective grip insert comprises a grip member connection portion such that the grip insert connection portion and the grip member connection portion co-operate to releasably attach the respective grip insert to said respective first or second grip member (220, 230), wherein the grip insert attachment system comprises: a first socket through the grip insert connection portion; a second socket through the grip member connection portion; and, a removable implement, wherein the removable implement is configured to be reversibly inserted through both the first and second sockets (820-822, 870-873) simultaneously to releasably attach the respective grip insert to said respective first or second grip member (220, 230). a first aperture configured to receive a respective grip insert for frictionally engaging the one or more panels of the temporary roadway; and, a grip insert attachment system configured to allow releasable attachment of the respective grip insert to the respective grip member, wherein the first aperture is one of a plurality of apertures configured to receive a plurality of respective grip inserts, wherein the plurality of apertures are arranged at different positions along a height of the respective first or second grip member, wherein the respective grip member comprises a grip insert connection portion characterised in that the respective grip insert comprises a grip member connection portion such that the grip insert connection portion and the grip member connection portion co-operate to releasably attach the respective grip insert to said respective first or second grip member (220, 230), wherein the grip insert attachment system comprises: a first socket through the grip insert connection portion; a second socket through the grip member connection portion; and, a removable implement, wherein the removable implement is configured to be reversibly inserted through both the first and second sockets (820-822, 870-873) simultaneously to releasably attach the respective grip insert to said respective first or second grip member (220, 230). a first socket through the grip insert connection portion; a second socket through the grip member connection portion; and, a removable implement, wherein the removable implement is configured to be reversibly inserted through both the first and second sockets (820-822, 870-873) simultaneously to releasably attach the respective grip insert to said respective first or second grip member (220, 230).
