Abstract
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 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 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.
