Significance
and Use
The amount of bituminous material
applied to a pavement surface using a bituminous distributor can be estimated
using the described procedure.
Apparatus
Test Method A and B:
Balance, sensitive to 0.1g.
Weighing Box or Balance Shield, to
protect balance from wind when the balance is in use at the project site (See
Figure 1).
Balance Table and work Table, for
weighing.
Test Method B:
Elliptical Containers, measuring
approximately 3.5 in. (88.9 mm) along the short axis and 9 in. ( 228.6 mm) in
height, capable of an internal volume of approximately 1 gal.
Rubber Bands, capable of a snug fit
when stretched around the elliptical containers.
Stopwatch, Capable of recording to
the nearest 0.1 s.
Materials
Test Method A:
Geotextile Pads, weighing a minimum of 8 oz.
/yd2 and measuring 12 in. (304.8 mm) by 12 in. (304.8 mm)
Aluminized Duct Tape, measuring 2 in (50.8
mm) wide and 6 in. (152.4 mm) long.
Butcher Paper #50, measuring 30 in.
(762 mm) by 950ft, for temporary protection of geotextile pads during
calibration.
Test Method B:
Plastic Bags, capable of fitting
inside the elliptical cans but of sufficiently larger dimension to allow
folding over the edge of the elliptical containers once placed inside.
