Standard Test Method for Thermal Compatibility Between Concrete and an Epoxy-Resin Overlay

ASTM C1884-23 制造混凝土道碴单元的标准规范

1.1 This specification covers dry-cast, manufactured concrete units that are primarily used for ballast applications. These units are machine-made from hydraulic cement, water, and suitable mineral aggregates with or without the inclusion of other materials.
