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

The typical bituminous 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 bituminous materials and aggregates and types and grades of bituminous materials for single and multiple bituminous surface treatments as applied to suitably prepared pavements or bases.

1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.
