Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to evaluate available foil-back and removable tapes as well as construction-zone raised pavement markers and to recommend materials that should be included on approved lists for use by the Kentucky Department of Highways. Tapes and markers were placed on transverse test sections and the reflectivity, durability, and appearance were observed. Tapes to be included on the approved lists for foil-back and removable tapes were recommended. Tapes manufactured by 3M, Flex-O-Lite, Cataphote, and Swarolite were included on the list of acceptable foil-back tapes. Recommended removable tapes were the 3M and Cataphote removable tapes. Stimsonite 66 and Flex-O-Lite construction-zone markers were included on the approved list for construction-zone raised pavement markers. More specific guidelines were developed to use in future evaluations of construction-zone preformed tape and markers.

Download or read book Evaluation of Pavement Markings for Improved Visibility During Wet Night Conditions written by Benjamin H. Cottrell and published by . This book was released on 1996 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the night visibility of waffle tape and paint with large beads, particularly during wet night conditions. Data were collected at two sites along a primary arterial. The evaluation included an examination of (1) the application of the markings, (2) the visibility of the markings using retroreflectometer measurements and subjective assessments, and (3) the costeffectiveness of the markings. The study revealed: (1) compared with paint with standard beads, the waffle tape and paint with large beads were slightly more retroreflective during light rain at night and recovered quicker after flooding out, (2) the marginal improvement in visibility during periods of light rain do not offset the operational problems of applying paint with large beads, and (3) the benefits of waffle tape during light rain do not appear to justify its use solely for wet night visibility. Because of the above findings, snowplowable raised pavement markers, which are very visible in wet night conditions, appear to be more cost-effective. The study recommends that (1) VDOT continue to use and maimain snowplowable raised pavement markers for visibility during wet night conditions, (2) VDOT continue to monitor FHWA's study on all weather pavement markings, and (3) the Suffolk District consider testing nonsnowplowable raised pavement markers to assess their use as a low-cost alternative to improve visibility during wet night conditions where snowplowing occurs infrequently.

Download or read book Durability and Retro Reflectivity of Pavement Markings Synthesis Study written by Yi Jiang and published by Purdue University Press. This book was released on 2007-05-01 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waterborne paints are used to paint pavement markings (edgelines and centerlines) to provide guidance for motorists. The painted markings need to be repainted periodically as their retro-reflectivity deteriorates. The Indiana Department of Transportation (INDOT) repaints pavement markings at least annually. INDOT engineers would like to determine the feasibility of extending the time intervals of repainting pavement markings on at least some types of roadways. The purpose of this synthesis study is to accomplish the following: (1) to locate and assemble documented information on pavement marking durability; (2) to learn what criteria have been used in other states in measuring retro-reflectivity and scheduling pavement marking painting; (3) to determine the necessity of conducting full scale study on INDOT pavement markings; (4) to identify the type and cost of equipment required for retro-reflectivity measurements and conditions of operation of the equipment; (5) to organize, evaluate, and document the useful information that is acquired; and (6) to provide recommendations based on the evaluated information. This report presents the findings of the synthesis study on various pavement marking materials. It was found in this study that many state highway agencies have evaluated several types of pavement marking materials. The evaluation results include performance, cost, service life, and retro-reflectivity measuring equipment of marking materials. However, the results could vary from different sates. The information gathered through this study will provide INDOT engineers the state-of-practice of pavement marking materials in this country.
