ASTM D2995-99(2009)

Standard Practice for Estimating Application Rate of Bituminous Distributors

SIGNIFICANCE AND USE
The amount of bituminous material applied to a pavement surface using a bituminous distributor can be estimated using the described procedure.
SCOPE
1.1 This practice covers the determination of transverse and longitudinal application rate of asphalt distributors in gallons per square yard (or litres per square metre).
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.
1.3 The values given in inch-pound units are to be regarded as the standard. The SI values given in parentheses are for information purposes only.
