Gse Effective specific gravity
Gb Specific gravity of the asphalt binder
Containers used for Cardboard boxes, metal cans, stainless steel bowls, or
sampling other agency approved containers
Thick metal, minimum 8 gauge, wire attached to
corner long enough to reach from the center of the
Specs for sampling plate
paver to the farthest auger extension. Min one 0.25 in.
hole in the corner of the plate
Permanently attached device that allows sampling
What is a Mechanical receptacle to pass through the entire stream of
Sampling Device material or diverts material into the container by
manual, hydraulic, or pneumatic operation
Non-stick product that prevents mix from sticking to
Release agent the apparatus (no solvents or petroleum based
products)
How do you determine Depends on test methods specified. Check agency
sample size requirement for size required.
-Coat or pre-heat it
-Pass container through twice, once in each direction
Explain the procedure for perpendicularly w/out overfilling
attached sampling devices -Transfer to sample container w/out loss
-Repeat until sample size is obtained
-Combine to form full sample
-avoid the beginning or end
-stop the belt
-place sampling template through the mix on the belt
Explain the procedure for
-remove mix from inside the template, including all
sampling from conveyor
fines and place in container
belts
-repeat, obtaining equal sized increments until sample
size is obtained
-combine
