• Rugged construction stands up to field use

• New Bucket-Liner sample bags streamline sample handling

• Proven history of accurate performance.

The SP-55 Quartermaster™ quickly and accurately divides the large bulk samples required in Superpave® specifications for quality control analysis. Hot-mix asphalt samples of 120lb (55kg) or more are easily reduced, ensuring representative samples for consistent laboratory results. The large hopper reduces handling of hot material during preparation of laboratory specimens. Quartermaster™ has a proven history of significantly reducing bias in sample reduction.

Once a bulk hot-mix asphalt sample is loaded evenly into the hopper, the handle is released and the sample falls through the divider, to be distributed equally into the four included galvanized steel containers. SPA-22 Bucket-Liner Sample Bags simplify collection and handling of divided specimens and eliminate cleaning of the sample containers. One person can easily collect and secure samples. Fabric and thread of the sturdy cotton Bucket-Liner bags are temperature-rated to 400°F (204°C). Optional Double-Loop Wire Ties and Wire Tie Twister allows bag openings to be quickly and securely closed. Only occasional clean-up is required to prevent buildup on the exposed splitting surfaces.

Rugged two-part steel construction stands up to field conditions and allows portability between jobsites. The SPA-21 Quick-Funnel Hopper Insert (purchased separately), drops into the top of the Quartermaster to significantly reduce hopper volume and allow accurate reduction of smaller samples. Four Galvanized Steel Sample Containers are included. Extras can be ordered to increase sample handling efficiency. Four Bucket- Liner Sample Bags are also included. Order extras as SPA-22 in quantities of ten. SPA-23 8in Double-Loop 16 gauge Wire Ties securely close bag openings when used with the SPA-24 Wire Twister. Optional HMA-68 Material Handling Chute allows fast loading of hopper. Assembled SP-55 is 14x17x48in (356x432x1,219mm), WxDxH. Est. Ship Wt.: 111lb (50kg).
