Download or read book The Evaluation of Epoxy Thermoplastic Pavement Marking Material in Virginia written by Eric Paltell and published by . This book was released on 1983 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epoxy Thermoplastic (ETP) is a recently developed epoxy-resin-based thermoplastic pavement marking material being promoted by the Federal Highway Administration as a possible substitute for conventional traffic paints and thermoplastics. Its reported advantages are excellent durability and adhesion, quick drying time, good visibility, lack of pollutants, and low cost. As part of its demonstration project program, the FHWA is field testing ETP in several states, including Virginia, in an effort to evaluate the performance of the material. The Virginia evaluation will compare the performance of a 5.8-mile section of ETP lane markings on Interstate 95 to that of a corresponding section of traffic paint on the same highway. The initial installation of the material in Virginia had several equipment and operational problems which resulted in varying thicknesses and distributions of beads along the ETP stripes. These problems and the resulting inconsistencies, as well as the properties of the ETP material and the layout of the Virginia installation, are discussed in this report.

Book excerpt: This report details the first year of a two-year project. During the first year the emphasis was on determining the wet-night visibility of various pavement marking systems under a variety of realistic rainfall levels. The researchers performed a literature review. They analyzed 20 years of Texas rainfall data to determine the most appropriate rainfall levels to use as design criteria for a rain tunnel. Using a low, medium, and high rainfall rate (0.28, 0.52, and 0.87 in. per hour, respectively), a 1600 ft long rain tunnel was designed and built at Texas A & M University's Riverside Campus. Experimental subjects drove through the rain tunnel and looked for pavement markings simulating skip lines. The researchers rotated pavement marking samples at different locations before each trial. The detection distance was recorded when the subject located the pavement marking sample. The data were analyzed in four main sections: waterborne paints, thermoplastics, tapes, and exotic materials. The analysis also included investigations into the wet-night visibility of rumble stripes, as well as wider lines. The measured dry and wet retroreflectivity measurements were analyzed, and the predictive capabilities of the wet retroreflectivity measurements were evaluated with respect to the wet-night detection distance of the markings.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to provide the Montana Department of Transportation (MDT) with information that will be useful in selecting cost effective pavement marking systems. This report begins with a description of available pavement marking technologies, including a discussion of performance parameters of importance and the advantages and disadvantages offered by the various technologies. A review of some of the pertinent studies completed by other states (Pennsylvania, Kansas, Minnesota, Virginia, Wyoming, North Dakota, and Idaho) on their pavement marking programs is subsequently presented. Based on the summary of the states included in this study, pavement markings such as conventional paints are viable in areas where pavement markings do not experience high levels of wear due to traffic or winter maintenance activities. In areas where more durability is required, such as intersections, highways in snowy areas, etc., durable products like epoxy paints or thermoplastics are justified. Since the MDT is able to procure epoxy paint markings for a very reasonable cost, greater use of this durable pavement marking is certainly justified, especially considering the level of wear Montana state highways experience from snowplowing and sanding. MDT investigation of the use of mid-durable paints is warranted due to increased durability and lower cost of these products. In spite of their high cost, extruded thermoplastics and preformed tapes are still viable in areas of high wear, such as intersections and urban streets, according to the results of the studies reviewed 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.
