ASTM D2995-99

Standard Practice for Determining Application Rate of Bituminous Distributors

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 problems, 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.

6.1.7 Weigh each pad to the nearest 0.1 g. Record the weight
of each pad and the pad position on the roadway on the report
form.
6.2 Test Method B:
6.2.1 Insert one plastic bag into each elliptical can. Wrap the
excess plastic over the top of the can and secure with a rubber
band.
6.2.2 Record the weight of the elliptical can, plastic and
rubber band assembly to the nearest 0.1 g.
6.2.3 Place one can assembly under each nozzle to be
calibrated in the spraybar of the asphalt distributor. Ensure that
the top of the can assembly is equal to or above the bottom of
each nozzle.
6.2.4 Activate the spraybar so that when the asphalt is
sprayed from each nozzle it is completely collected in each
preweighed can assembly. Start the stopwatch the instant the
asphalt begins to fill the can assembly.
6.2.5 Stop the flow of asphalt to the spraybar when the can
assembly is approximately ⁄4 full. Stop the stopwatch the
