• Abstract:
  Pavement markings provide an important means of communication for all roadway users and must be capable of conveying ; information during inclement weather and evening hours when there may be little to no contribution from overhead lighting. The ; following report outlines the observations concerning the second application of an experimental pavement marking, known as ; Aexcel Roadzilla™ Methyl Methacrylate, with respect to long line application. In addition, the report contains information ; pertaining to field data collection to assess the luminance, durability, and the ability to uphold the retroreflectivity requirements ; over time. ; The Aexcel Roadzilla™ Methyl Methacrylate was applied on the Chester Bridge #49 deck replacement BHF-ST 0134 (31) ; project, located along VT Route 11 at approximately mile marker (MM) 5.7 by the manufacturer, Aexcel Corporation of Mentor, ; Ohio. The rolled beam bridge structure has approximately an 82’-0” span. A total of 34 readings were taken on both the white ; edge lines and yellow centerlines on the concrete surface. On the bituminous concrete bridge approaches, 18 readings were ; taken on the white edge lines and 12 readings were taken on the yellow centerlines. Following the placement of the markings, ; retroreflectivity and wear readings were collected using uniform methods. Retroreflectivity readings were taken on each line ; (white edge, white skip, yellow edge) at five-foot intervals on both the bare concrete bridge deck surface and bituminous concrete ; bridge approaches using the LTL 2000 Retroreflectometer. Readings were collected four times over the course of the first year ; of the evaluation. At the fourth site visit, it was determined that due to the poor performance of the yellow centerline, it needed to ; be reapplied. All readings were taken after the reapplication of the yellow. The first year there were losses of retroreflectivity of ; 83% of the white on concrete and 93% of the white on asphalt. For the first application of the yellow markings, there was a loss ; of 89% on concrete and 94% on asphalt. For the reapplication, the yellow markings had losses of 92% on the concrete and 81% ; on the asphalt. The following report summarizes the application, performance and observations
