![]() On many occasions, rather than obliterating the existing stripe, it is more cost-effective and convenient to simply restripe over the old pavement markings without removing them, assuming that the old pavement markings still adhere well to the roadway. Therefore, such pavement marking materials shall be used on ODOT-maintained highways wherever pavement conditions permit the material to achieve its expected service life while providing comparable economy to alternative materials.Īll pavement marking materials will at some point reach the end of their useful life. The use of pavement marking materials which are capable of longer service lives than that of traffic paint can result in benefits of reduced frequency of renewal, less exposure of the public and workers to the hazards of the pavement marking operation, and a higher percent of time markings are present on the roadway. Pavement marking materials for application on ODOT-maintained highways should be selected from Table 397-1. ODOT currently employs the following material types for pavement markings on ODOT-maintained highways: traffic paint, polyester, thermoplastic, preformed, epoxy, heat-fused preformed thermoplastic and spray thermoplastic. ![]() 301-2 Selection of Pavement Marking Materials Additional information is also presented in TEM Chapters 704, 802 and 902, respectively. ![]() Markings information specifically related to School Areas, Highway-Rail Grade Crossings and Bicycle Facilities is addressed in OMUTCD Chapters 7C, 8B and 9C, respectively. The general standards for curb markings are addressed in OMUTCD Section 3B.23. Raised pavement markers (RPMs) are addressed in OMUTCD Part 3 and in Chapter 302 of this Manual. TEM Chapters 340 through 343, 350 and 360 present additional design, specification and Supplement information, and Traffic Standard Construction Drawings (SCDs) TC-71.10 and TC-72.20 also provide additional design and application information.Ī raised pavement marker is a special form of pavement marking intended to be used as a positioning guide with longitudinal line markings, or to supplement or substitute for pavement markings. Additional standards and guidelines are provided herein. OMUTCD Chapters 3A and 3B present information on pavement markings. 301 PAVEMENT & CURB MARKINGS 301-1 General It should be recognized, however, that the information in the C&MS and SCDs does not necessarily provide the only method to achieve a given objective. It is recommended that the Districts also follow the provisions in the applicable markings-related Standard Construction Drawings (SCDs) and Construction and Materials Specifications (C&MS) sections as well. 300-3 Force Account (ODOT Operations) Workĭistricts performing force account markings work shall comply with the requirements in the OMUTCD and this Manual. Chapter 350 provides additional construction related information specific to traffic control markings. 300-2 Construction ProjectsĬhapter 140 addresses the general application of ODOT standards, specifications and standard drawings to construction projects. The information provided in this Part of the TEM is intended to supplement the OMUTCD by presenting ODOT practices and procedures concerning the design, construction, operations and maintenance of various types of traffic marking devices such as pavement markings (including raised pavement markers), barrier reflectors and delineators.
