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.

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.

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.
