A pavement marking and methods of making pavement markings are disclosed in which the pavement markings exhibit enhanced wear resistance to, e.g., snowplow blades. The pavement markings include elongated protuberances (30) in which successive elongated protuberances overlap along at least the longitudinal direction and may also overlap in a direction transverse to the longitudinal axis. Other protuberances (20) are interspersed between the elongated protuberances to improve retroreflectivity. The elongated protuberances are provided to support, e.g., a snowplow blade moving over the pavement marking.
La présente invention concerne un marquage de chaussée et des procédés de production de ces marquages qui possèdent une résistance à l'usure améliorée, par exemple, aux étraves de chasse-neige. Les marquages de chaussée comprennent des parties saillantes allongées (30), parmi lesquelles des parties saillantes allongées successives se chevauchent dans le sens longitudinal au moins et peuvent également se chevaucher le sens transversal à cette direction. D'autres parties saillantes (20) sont intercalées entre les parties saillantes allongées de manière à améliorer la rétroréflectivité. Les parties saillantes allongées sont destinées à supporter, par exemple, une étrave de chasse-neige qui se déplace sur le marquage de chaussée.
