|ICS Code (Bridge construction):||93.040|
|ICS Code (Road construction materials):||93.080.20|
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.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.4 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.
1.5 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.

This specification covers the standards 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. This specification is limited only to field molded APJ which can consist of multilayer, or single layer, or both, application systems. The asphaltic binder to be used shall be a thermoplastic polymeric-modified asphalt. The aggregates shall be crushed, washed, and dried. Physical properties of the asphalt such as softening point, tensile adhesion, ductility, resilience, and flexibility shall also be tested and shall conform to other ASTM documents prescribed herein.View Less
