• 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. Recently the Agency has been applying recessed polyurea markings on most interstate rehabilitation ; projects. Recessing has proven effective in extending the service life of pavement markings by protecting them from ; wear induced by tire abrasion and shearing effects generated by snow plows. This research was conducted to evaluate ; the application of an experimental pavement marking, known as Epoplex Glomarc 90 Polyurea, with respect to long line ; application. ; The Epoplex Glomarc 90 Polyurea was applied on the Derby IM 091-3(46) project, located along I-91 northbound and ; southbound between mile marker (MM) 169.8 and 177.4. Five test sites were established in the southbound lanes of the ; project, all of which were experimental. 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) ; within the southbound test site limits using the LTL 2000 Retroreflectometer. Each test site is 40 feet in length, with ; readings sampled every 10 linear feet. White skip lines that coincide transversely with any sample point were also tested. ; All markings were found to be in compliance with FHWA recommended minimum Retroreflective values, and above the ; Agency’s required initial retroreflective values of 500 mcdl/m ; 2 ; /lx for white, and 400 mcdl/m ; 2 ; /lx for yellow. The most ; notable observation during the site visit was that on average, the yellow markings were presenting higher retroreflective ; values than the white lines. Research personnel will continue to monitor and collect additional information concerning the ; overall durability and retroreflectivity of all test sites in accordance with the work plan.
