Pavement marker and mounting base member

Abstract

Abstract IN A PAVEMENT MARKER CAPABLE OF SERVICE IN SNOW AREAS AND HAVING A REFLECTOR FOR ESTABLISHING A MARKING VISIBLE FROM AN ONCOMING VEHICLE ON A ROADWAY SURFACE, A BASE MEMBER CONSTRUCTED FOR SECURING THE PAVEMENT MARKER TO THE ROADWAY SURFACE AND FOR PROTECTING THE REFLECTOR AGAINST DAMAGE FROM AN ONCOMING SNOWPLOW BLADE DURING SNOW PLOWING OPERATIONS, THE BASE MEMBER HAVING A BODY OF HIGH STRENGTH MATERIAL, PREFERABLY A METAL, AND INCLUDING SIDEWALLS WITH INCLINED RAMPS AT EITHER SIDE OF THE REFLECTOR FOR GUIDING AN ONCOMING SNOWPLOW BLADE OVER THE REFLECTOR WITHOUT DAMAGING CONTACT, AND SECURING SURFACES EXTENDING LONGITUDINALLY ALONG THE BODY PARALLEL TO ONE ANOTHER AND PROJECTING DOWNWARDLY INTO COMPLEMENTARY GROOVES IN THE PAVEMENT, THE SECURING SURFACES PREFERABLY LYING ON DOWNWARD EXTENSIONS OF THE SIDEWALLS AND PERPENDICULAR TO THE ROADWAY SURFACE. AUXIALIARY SURFACES MAY BE PROVIDED ADJACENT THE INCLINED RAMPS AND PARALLEL TO THE ROADWAY SURFACE FOR RESTING UPON THE ROADWAY SURFACE AND PROVIDING INCREASED RESISTANCE TO DOWNWARD MOVEMENT OF THE BODY WHEN THE INCLINED RAMPS ARE CONTACTED BY A SNOWPLOW BLADE. IN ADDITION, THE DOWNWARD EXTENSIONS MAY TERMINATE IN A SERIES OF STEPS WHICH FOLLOW A GENERALLY ARCUATE PATH SO THAT THE GROOVES IN THE PAVEMENT MAY BE ARCUATE, BUT THE STEPS WILL RESIT ROCKING MOVEMENT OF THE EXTENSIONS IN THE GROOVES.
