 ASTM D 2041 (Type E)
AASHTO T 209, T 283
The A-516 is used in
Rice Testing for
bituminous mixes with
maximum aggregate
size of ¾ in (19.1 mm).
The 2000 g capacity
vacuum pycnometer
has 4.5 liter (1.2 gal)
capacity.
Unit supplied with two
lids. A transparent lid
on the pycnometer allows the operator to observe the
bubble release from the asphalt sample during the vacuum
test. A second volumetric lid of machined aluminum,
tapered with a capillary bore, is provided so the unit can be
used as a volumeter for determing the specific gravity of
compacted bituminous mixes.
A-518 is an optional 1500 gram capacity pycnometer
where the chamber is only 4-in deep and used for mixes
with aggregate sizes up to ½ in.
The A-516 or A-518 set includes an aluminum volumetric
canister, volumetric lid, flat Plexiglass vacuum lid with Oring,
volumeter, a vacuum gauge, release valve, fittings, a
metal aspirator with 3/8 in IPT fittings and 6 ft of hose.
