1.1 本规范涵盖了一种反光热塑性路面条带材料，该材料通过熨平板/挤出或条带挤出方式在熔融状态下应用于路面。路面标线化合物的反光最初是通过在路面标线应用时表面应用反光光学器件来实现的。在冷却至正常路面温度后，路面标记材料会产生一条规定厚度和宽度的粘附反光条，能够抵抗交通变形。路面标记化合物包括反光光学器件（玻璃珠或复合光学器件，或两者），在制造时结合到材料中，在材料的使用寿命期间提供反光性能。 1.1.1 本规范仅限于: 1.1.1.1 在非雪犁地区的纵向应用， 1.1.1.2 标准（非剖面）路面标记应用，以及 1.1.1.3 适用于光滑的沥青或混凝土表面。沥青封层应用不包括在本规范范围内，该应用使用大骨料，从而形成非常粗糙的开放式表面。 1.1.2 本规范包括: 1.1.2.1 热塑性路面标记材料的组成和物理性能要求， 1.1.2.2 对用于在应用后反射热塑性路面标记材料的光学器件的要求， 1.1.2.3 安装的热塑性路面标线的现场性能要求，以及 1.1.2.4 材料应用要求。 1.2 除非文件中另有说明，否则以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers a reflectorized thermoplastic-based pavement striping material of the class that is applied to the road surface in a molten state by screed/extrusion or ribbon extrusion means. Retroreflectivity of the pavement marking compound is achieved initially by surface application of retroreflective optics at the time of pavement marking application. Upon cooling to normal pavement temperature, the pavement marking material produces an adherent reflectorized stripe of specified thickness and width capable of resisting deformation by traffic. The pavement marking compound includes retroreflective optics (glass beads or composite optics, or both) that are incorporated into the material at the time of manufacture that provide retroreflective properties during the service life of the material. 1.1.1 This specification is limited to: 1.1.1.1 Longitudinal applications in non snow plow areas, 1.1.1.2 Standard (non-profile) pavement marking applications, and 1.1.1.3 Applications on smooth asphalt or concrete surfaces. Asphalt seal coat applications, which use large aggregate resulting in a very rough, open grade finish, are excluded from this specification. 1.1.2 This specification includes: 1.1.2.1 Compositional and physical property requirements of the thermoplastic pavement marking material, 1.1.2.2 Requirements for the optics that are used to reflectorize the thermoplastic pavement marking material after application, 1.1.2.3 Field performance requirements for the installed thermoplastic pavement markings, and 1.1.2.4 Material application requirements. 1.2 The values stated in inch-pounds units are to be regarded as the standard except where noted in the document. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
