Book Synopsis Durability and Retro-Reflectivity of Pavement Markings (Synthesis Study) by : Yi Jiang
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.

Book Synopsis Determining the Effectiveness of Pavement Marking Materials by : Benjamin H. Cottrell
Download or read book Determining the Effectiveness of Pavement Marking Materials written by Benjamin H. Cottrell and published by . This book was released on 2001 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to determine the safety, motorist opinion, and cost-effectiveness of pavement marking materials used by the Virginia Department of Transportation and to develop guidelines, where possible, as to when each type of material should be used. Interstate and primary road segments that had been remarked with a different type of pavement marking material were identified to perform a before-and-after accident analysis. When possible, segments that were remarked using the same pavement marking material were included to provide comparison sections. The number of sites and accident count data were insufficient to support a finding that the use of a particular pavement marking material reduces the number of target accidents. The results of a motorist survey indicated that the participating drivers were more satisfied with pavement markings with higher retroreflectivity values than those with lower values. Participating drivers over the age of 65 were generally less satisfied with the brightness of the pavement markings than were participating drivers under the age of 65. Using a large contract for paint was the most cost-effective for two-lane roads under most volume conditions and four- and six-lane low-volume roads. Using polyurea and a large contract for paint were the most cost-effective for high-volume two- and four-lane roads. Polyurea and waffle tape were the more cost-effective durable markings for high-volume six-lane roads. Changes in the use of pavement markings were recommended. Specifically, the Virginia Department of Transportation should (1) consider increasing the use of large paint contracts and minimizing its use of small paint contracts when possible; (2) consider a performance-based specification for durable markings; (3) continue consideration of a holistic approach for pavement management and markings, and (4) re-evaluate its pavement marking policy and include the recommendations of this study.
Book Synopsis Evaluation of Construction-zone Pavement Marking Materials by : Kenneth R. Agent
Download or read book Evaluation of Construction-zone Pavement Marking Materials written by Kenneth R. Agent and published by . This book was released on 1987 with total page 32 pages. 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 Pavement Marking Performance Analysis written by and published by . This book was released on 2009 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research evaluated pavement marking performance and developed useful degradation models for thermoplastic and paint pavement markings which can help North Carolina meet the pending FHWA minimum retroreflectivity requirements. The impacts of several important factors (such as lateral location, directionality, region, and pavement roughness) on pavement marking retroreflectivity were evaluated. With two large datasets in hand, the authors determined whether these factors had significant impacts on marking retroreflectivity. Image processing techniques were used to analyze pavement marking surface glass bead density. The authors were able to explain why paint marking retroreflectivity values degraded over time by evaluating the impact of bead density on paint marking retroreflectivity. The research reviewed existing marking retroreflectivity degradation models and developed useful new models for both thermoplastic and paint pavement markings in North Carolina. The research presented a transportation asset management system framework for estimating the current and future condition of pavement markings. The research outcomes enable the North Carolina Department of Transportation to have a better understanding of thermoplastic and paint pavement marking performance, which can lead to cost saving by maximizing pavement marking service lifecycles.

Book Synopsis Evaluation of Pavement Markings for Improved Visibility During Wet Night Conditions by : Benjamin H. Cottrell
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.
