Superpave Gyratory Compactor

Superpave Gyratory Compactor

The Superpave Gyratory Compactor by Pine Instruments is a proudly American-made machine designed to prepare hot-mix asphalt specimens for Superpave mix design operations. During compaction, a mold containing an asphalt specimen is gyrated on its longitudinal axis at a fixed angle while the end platens remain parallel, ensuring consistent and reliable specimen preparation. Beyond hot-mix asphalt, this versatile compactor is also capable of testing a wide range of materials, including soils, emulsion-based mixes, and roller-compacted concrete. Please note that Mold Assemblies are sold separately.

Advanced Control & User Settings

The Superpave Gyratory Compactor offers a high degree of user control, with variable settings for compaction pressure, angle adjustment, gyrations, and mold size adaptability. This flexibility makes it suitable for a wide variety of applications. The machine features an integrated computer with two USB ports and an Ethernet jack, which manages all settings through a simple, intuitive menu interface. A four-button control panel further simplifies day-to-day machine operation.

The computer also controls the angle of gyration and allows users to easily switch between internal and external angle settings. The control system is fully network compatible, enabling complete data management. Key data points — including the number and angle of gyrations, specimen height, and consolidation pressure — can be transmitted via Ethernet cable to a network or standalone PC, stored on a flash drive, or printed directly using the optional PCL Laser Printer.

Operation Modes & Specifications

The compactor offers three operation modes: a specified number of gyrations, a specified sample height, or a locking point, all selectable at either an internal or external angle. Key specifications include:

• Total Gyrations: 0 to 999, at 30 ±0.5 gyrations per minute
• Angle of Gyration: 0° to 1.50° internal or external
• Compaction Pressure: 200 to 999 kPa
• Final Specimen Height: User-controlled from 0 to 200mm
• Mold Sizes Available: 150mm, 100mm, or 4.0in diameter specimens

Safety & Convenience Features

The Superpave Gyratory Compactor is designed with operator safety and convenience in mind. A built-in specimen extruder minimizes the need to lift hot, heavy molds, while a completely enclosed compacting chamber shields operators from moving parts during operation.
