1.1 本试验方法涵盖当二者的组合受到现场可能遇到的温度变化时，当用作混凝土覆盖层时，哪些环氧树脂配方会发生脱粘。 1.2 单位- 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。合并两个系统的值可能会导致不符合规范。 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）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 第节给出了具体的危险说明 8. . . ( 警告 -新鲜的水硬性胶结混合物具有腐蚀性，长时间接触可能会对暴露的皮肤和组织造成化学烧伤。 ) 2. ====意义和用途====== 5.1 本试验方法适用于混凝土路面用环氧砂浆罩面材料。如果覆盖层和路面之间发生脱粘，则该材料不适用。 5.2 本试验方法评估了覆盖层在显著温度范围内的空气中重复热循环期间保持与混凝土基材粘结的能力，其目的不是复制现场的温度波动。

1.1 This test method covers the determination of which epoxy-resin formulations are subject to debonding when used as overlays for concrete when the combination of the two is subjected to temperature changes that may be met in the field. 1.2 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification. 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 and health practices and determine the applicability of regulatory limitations prior to use. A specific hazard statement is given in Section 8 . . ( Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to exposed skin and tissue upon prolonged exposure.) 2 ====== Significance And Use ====== 5.1 This test method applies to materials used in making epoxy-mortar overlays for concrete pavement. If debonding occurs between the overlay and the pavement, the material is unsuitable. 5.2 This test method evaluates the ability of an overlay to remain bonded to a concrete substrate during repeated thermal cycling in air over a significant temperature range and is not intended to duplicate temperature fluctuations in the field.
