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.

Available in PDF, EPUB and Kindle. Book excerpt: Traffic markings that retain high reflective properties under adverse lighting and weather conditions are clearly of utmost importance in traffic safety. It was the intent of this study to investigate optimum traffic striping procedures and materials by evaluating such variables as: (1) Certain characteristics of glass beads, namely their gradation and flotation properties; (2) Rate of bead application; and (3) Type of paint, including fast and slow drying paints. As a consequence of problems encountered with the control of the bead and paint application rates, the evaluation of the striping procedure and materials was limited. However, based on the results the following conclusions are presented: (1) Insufficient evidence was obtained to indicate that any one of the three bead types used was superior to the other in brightness under dry night conditions; however, it appears that the floating bead has an advantage over the non-floating bead under wet night conditions as the stripes with the floating bead were visible for further distances. (2) No clear advantage was noted for either of the two bead application rates used. (3) The fast drying paint used seemed to compare favorably with the slow drying paint, which supports the Department's decision for more extensive use of fast drying pavement marking paint in the immediate future. It is suggested that before additional in-depth studies are considered the results of a 1971 NCHRP Project entitled "Development of Optimum Specifications for Glass beads in Pavement Markings" be awaited, as many of the objectives of this NCHRP project should touch upon many of the unanswered questions in this report.
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.

Available in PDF, EPUB and Kindle. Book excerpt: This research work evaluated four pavement marking materials installed on pavements at 11 test sites located at ODOT District 11. Fast dry traffic paint, polyester, epoxy and thermoplastic were the four marking materials installed at the sites across the district on two-lane and four-lane highways having a variety of pavement types, pavement geometries, and traffic volumes. The main focus was to evaluate fast dry traffic paint and polyester as a restriping material, while epoxy and thermoplastic were evaluated for a purpose of comparison. Most of the sites were located on two-lane roads in rural locations, with an average daily traffic (ADT) of less than 5,000 vehicles per day and an average daily truck traffic (ADTT) of less than 1,000 trucks per day. Only two four-lane sites (located along US 22 in Jefferson County) were included because of their high traffic levels and to facilitate the comparison between two-lane and four-lane roads. Marking materials were installed on a 2 mile road section. The test section was divided into 4 segments each with a 0.5 mile length. In order to evaluate the performance of polyester and fast-dry traffic paint as restriping materials, a 0.1-mile portion of the right edge line in the middle of Sections 1 and 4 was left intact so that both materials could be installed over the existing markings. For the remaining portion of the sections, polyester and fast-dry traffic paint were installed on bare pavement surfaces after the removal of the existing pavement markings. Epoxy and thermoplastic was installed after removing existing marking material. Centerlines were restriped with polyester at section 1 and paint at other sections. During a two year period, the pavement markings were evaluated in terms of dry retroreflectivity, daytime color and durability. A handheld Delta LTL-X retroreflectometer was used to measures pavement marking retroreflectivity in accordance with CEN and ASTM standards using a 30-m geometry to simulate the roadway being illuminated by the headlights of a car. A MiniScan XE Plus (Model 4500L) spectrocolorimeter was used to measure the daytime color of the markings. Durability was evaluated using a subjective rating as an integer on a scale of 0 (the material is completely missing) to 10 (where 100% of the material remains). Photographs were taken to document the condition of the markings for future reference. Laboratory testing was also conducted to examine the quality of the glass beads used during the marking installation. Finally, statistical analysis was performed on the initial and two-year field evaluation data using Minitab 17. Effect of various factors (such as the pavement type, line type, marking material and color, etc.) on the retroreflectivity performance of the pavement markings were determined. The service life of all marking materials was estimated using the linear and the power models for each line at all test sites using a minimum retroreflectivity value of 100 mcd/m2/lux. A Microsoft Excel macro was developed to handle the large amount of data involved in the analysis. Based on the analysis result different restriping strategies were proposed along with the cost analysis for the whole district. Material selection matrices were presented for the two-lane and multi-lane roadways which will help the district office in strategy development and decision making.
