ASTM D1369-19

4.1 This practice is intended to be used as a guide by those involved in the design of asphalt surface treatments. It covers typical application rates for the various types of surface treatments and covers aggregate sizes and recommended grades of asphaltic material for both hot and cool weather conditions.

4.2 The typical asphalt material application rates given are for normal surfaces and non-porous aggregates. Provision is made for rate adjustment when other than normal surfaces or porous aggregates, or both, are involved.

1.1 This practice covers the rates of application of asphalt materials and aggregates and types and grades of asphalt materials for single and multiple asphalt surface treatments as applied to suitably prepared pavements or bases.

1.2 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.3 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 nonconformance with 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.
