ASTM C884 – Standard Test Method for Thermal Compatibility Between Concrete and an Epoxy-Resin Overlay
Description:
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.
Scope
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 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.
