ASTM D2995-23
(Practice)Standard Practice for Estimating Application Rate and Residual Application Rate of Bituminous Distributors
Standard Practice for Estimating Application Rate and Residual Application Rate of Bituminous Distributors
SIGNIFICANCE AND USE
3.1 Option A—The transverse and longitudinal application rate and variability in application rate of bituminous material applied to a pavement surface using a bituminous distributor can be estimated using Option A.
3.2 Option B—The transverse and longitudinal residual application rate and variability in residual application rate from emulsified asphalt applications to a pavement surface using a bituminous distributor can be estimated by using Option B.
SCOPE
1.1 This practice covers the determination of transverse and longitudinal application rate and residual application rate of asphalt distributors in gallons per square yard (or litres per square metre).
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
1.4 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.
