Standard Specification for Asphaltic Plug Joints for Bridges
standard by ASTM International, 07/01/2020



1.1 This specification covers the material, testing, and application requirements for a field-molded asphaltic plug joint (APJ) used in expansion joint sealing on asphalt concrete overlay and portland cement concrete decks. The scope of this specification is limited to field-molded APJ. This molded element can consist of multilayer or single layer, or both, application systems depending upon individual manufacturing requirements. The details of this specification are limited to the materials used in the application of APJ. It is recommended that a practical means of testing the watertightness aspects of the individual systems, either in the field or at the testing laboratory, be developed. When used on highway bridges, limits on maximum joint movements shall be specifically identified for each type of APJ. APJs should not be used for movement applications exceeding ±25 mm from the installation width.
