Quartermaster Asphalt Sample Divider

Gilson SP-55 is a fixed, four-chute splitter with a gate-release hopper designed to reduce bulk samples of hot-mix asphalt and aggregate materials to four representative specimens.

The SP-55 is easy to assemble and operate, and it can be used to accurately divide samples of up to 2 inches in size. The unit is also equipped with adjustable threaded feet, which allow it to be leveled on uneven surfaces.

The SP-55 is a valuable tool for anyone who needs to accurately divide samples of hot-mix asphalt or aggregate materials. It is a durable, well-made unit that is built to last.

INTRODUCTION

The SP-55 Quartermaster Asphalt Sample Divider is a xed, four-

chute splitter with a gate-release hopper designed to reduce

bulk samples of hot-mix asphalt and aggregate materials to four

representative specimens. Hot-mix asphalt of insucient tem-

perature to be free-owing or aggregate materials larger than

2in may cause bridging in the chutes, causing blockages and un-

even sample distributions. We suggest following the guidelines

in ASTM and AASHTO procedures to achieve accurate, represen-

tative samples.

ASSEMBLY

1. Place the base unit of the Quartermaster Asphalt Sample Di-

vider with four adjustable threaded feet on a smooth, rigid

surface.

2. Place a level across the corners of the base unit, and adjust the

threaded feet so the base is stable and level.

3. Place the hopper section of the Sample Divider on top of the

base. Verify the assembled unit remains stable and level.

4. Slide the four included MA-950 Galvanized Pails under the

base, so that each makes contact with two adjacent legs and

is positioned beneath the chutes. The handles of the buckets

should be facing away from the center of the unit for ease

of handling after splitting. Use of the heavy cotton SPA-22

Bucket Liner Bags simplies clean-up and sample handling.

5. Close the hopper by swinging both hopper doors upward

and engaging the release handle under the hopper door

catch mechanism.

OPERATING INSTRUCTIONS

1. Check that the hopper doors are closed and secured with

the handle/door catch mechanism.

2. Obtain the aggregate or hot-mix asphalt bulk sample to be

quartered. (See WARNING!)

3. Place the bulk sample into the hopper, distributing evenly as

you pour. Level the sample from side-to-side and from front

to back with a small scoop or trowel.

4. Make sure all four buckets are positioned properly below

each corner of the Sample Divider base.

5. Turn the Release Handle in a smooth, quick motion, allowing

the hopper gates to open simultaneously.

6. Remove the four specimens for testing.

NOTE: For accurate dividing of smaller bulk samples, the

optional SPA-21 Quick Funnel inserts into the SP-55 Hopper.

For further reductions in sample size, use samples from two op-

posite corners, combine in hopper and repeat splitting process

until the desired fraction is reached: 1/8, 1/16, 1/32, etc.

For easier clean-up of hot-mix asphalt samples, apply a coat of

release agent on all surfaces that are likely to come in contact

with the asphalt. Please make sure release agents are approved

for use with asphalt and will not change the characteristics of

the mix being tested.

WARNING!

Asphalt paving materials are hot! Please use EX

TREME CAUTION! ALWAYS wear protective cloth-

ing and safety equipment to prevent burns and se-

rious injury.

2. ALWAYS practice proper lifting techniques when han-

dling large samples.

3. Use CAUTION when opening the hopper door to pre-

vent injuries from pinching action of the hopper door

and the release handle mechanism.

4. Proper attention to safety is the responsibility of the op-

erator.
