EVALUATION OF RETROREFLECTIVE DURABILITY OF RAISED PAVEMENT MARKERS

The Louisiana Department of Highways began using reflectorized raised pavement markers on a large scale basis in 1967 when such markers were placed on the Mississippi River Bridge along Route I-10 at Baton Rouge. The Department has engaged in a considerable amount of research since 1967 in order to derive the most benefit from reflectorized raised pavement markers. A standard test procedure for measurement of retroreflection of reflectorized markers has previously been developed and adopted. A supplemental specification was also written which now requires initial minimum retroreflection values before any given brand of marker may be placed on our highways. The report documents a research effort to establish a rapid method of evaluating the nighttime retroreflective durability of reflectorized raised pavement markers and to develop source acceptance criteria keyed to this test method.
