ABSTRACT:
A temporary roadway marker having an L-shape that includes a base adapted to be attached to the roadway surface and an upwardly extending leg on which a reflective strip may be mounted is disclosed. The body of the roadway marker is formed of two materials having different flexural moduli, thus allowing the upper portion of the roadway marker to be formed of a material having a flexural modulus similar to that of the reflective strip. This helps to prevent stress concentration in the interface in between the reflective strip and the upper portion of the roadway marker, thus reducing cracks and failure of the reflective strip. In addition, it allows the base and the transition between the base and the upwardly extending leg to be formed of a more flexible material, which allows better flexing without breakage and the base to conform to the roadway surface. The roadway marker may also include a reverse curve, or nubbles located on opposite sides of the interface, between the upwardly extending leg and the base of the roadway marker to decrease stress concentrations when the leg deforms upon contacting a vehicle's tire.
