The rugged and proven Brovold Gyratory Compactor is an industry-leader for portability and ease of use when compacting hot-mix asphalt specimens to Superpave™ mix design requirements. This reliable model is built by Pine Instruments and is ideal for both mix design and QC/QA applications. The self-contained unit is lightweight and easily transported to remote sites or mobile labs. An integrated industrial computer controls the entire specimen compaction cycle. After compaction parameters are entered through the simple, menu-driven controller and the prepared mold is set in place, simply secure the gyratory head and press start. The system automatically applies consolidation pressure, induces the angle, and gyrates the mold to the specified settings. At completion, the specimen is extruded with the same hydraulic ram used for compaction, eliminating handling of hot, heavy molds. Rigid tubular frame design and patented gyratory mechanism assure accurate, repeatable results.

The HM-687 Brovold Gyratory features integrated data logging functionality designed by Pine to save or export data to a portable USB flash drive, or output directly to an optional PCL Laser Printer. Up to ten completed tests are stored in the compactor’s internal memory, and data is also output to the two USB ports for flash drive and printer as well as a RS232 serial port. Test data can also be viewed in real time on the four-line digital display. Default settings of the HM-687 control compaction of specimens to the height, number of gyrations, compaction force and speed required by the standard ASTM and AASHTO test methods. All of these parameters can be reset by the user for special applications and different materials. Default internal angle of gyration is 1.16° and 1.25° external. The angle can also be factory set to 0.82° internal if specified when ordering.

Compaction forces are supplied through a hydraulic/electro-mechanical system. The user can select a specimen squaring function to specify the amount of time pressure is applied to a specimen after squaring, from 0 to 16 seconds in 2-second intervals.

Electrical requirements are 115V/60Hz for the HM-687 and 230V/50-60Hz for the HM-687F.
