Book Synopsis Development of Improved Pavement Marking Materials by : John M. Dale
Download or read book Development of Improved Pavement Marking Materials written by John M. Dale and published by . This book was released on 1967 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory tests and field studies were conducted on the performance characteristics of conventional pavement marking materials currently in use. A discussion was presented of their shortcomings and studies conducted on the physical nature of reflective materials, with particular emphasis on performance characteristics under various types of water films. A new pavement marking was designed and tested with encouraging results. A systematic approach for the design of a pavement marking system has been developed wherein one qualifies the surface to be marked, determines the water film thickness to be encountered, and then selects one of the several marking systems that will perform under the imposed conditions.

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.

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.

Book Synopsis Permanent Concrete Pavement Markings by : David Darwin
Download or read book Permanent Concrete Pavement Markings written by David Darwin and published by . This book was released on 1994 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visibility, durability, and cost-effectiveness of surface pavement markings and previous experience with permanent concrete paving markings (PCPM) (markings with a service life similar to that of the pavement) are described. The use of durable materials, such as thermoplastics, polyesters, and epoxies, improves the service life of surface markings. However, these marking materials still exhibit problems of adhesion to pavement and rapid wear in high traffic areas. Snow removal procedures significantly reduce marking service life. Wet nighttime visibility is a continuing problem with surface markings. Previous attempts at developing PCPM have produced systems with very good durability, but poor nighttime visibility. The potential for developing cost-effective PCPM systems that can provide both long-term durability and adequate visibility throughout the service life and the requirements for such systems are discussed. Polymers, such as epoxies, can provide superior durability and adhesion to pavement. The application of larger than standard size glass beads can improve wet nighttime visibility. The cost of PCPM systems can be significantly reduced using effective methods of placing grooves in which the marking material is placed. Generally, there is a good probability that a cost-effective PCPM system with satisfactory durability and visibility can be developed. The PCPM systems with thicknesses of 9.5 mm (3/8 in.) or less will be cost-effective for a 20-year service life, and the systems with thicknesses of 3.2 mm (1/8 in.) or less will be cost-effective for a 10-year service life.
