Abstract
Marker devices, each comprising a base with an upright post thereon, are molded from an elastomeric material. A marker device is attached by adhesive on the base thereof to each paint striping on a worn down street and each maintenance cover mounted on the worn down street. Once the marker devices are in place on the worn down street, the posts thereof must withstand the punishment of not only being flattened by truck tires, and the tracts of a paving machine that is being used to lay down the new coating of hot asphalt on the worn down street, but also the hot asphalt, and still spring back to their upright position. Thus, when the stripings are to be repainted on the resurfaced street and when the maintenance covers are to be adjusted upwardly to the level of the new coating of asphalt on the resurfaced street their exact locations on the street are immediately indicated by the posts of the marker devices without having to make any measurements.
