AutoRice - Automatic Rice Test Control System

The AutoRice, by InstroTek, automatic Rice-test controller helps laboratories perform theoretical maximum specific gravity testing with more consistent vacuum control and less manual intervention. It manages key vacuum parameters and can monitor shaker activity, allowing technicians to focus on specimen preparation and results review. Its compact, menu-driven interface and downloadable records support a more repeatable, auditable asphalt testing workflow.

Key Features

• Automates vacuum pressure and timing for AASHTO T 209 and ASTM D2041/D2041M testing and supports saturation workflows associated with AASHTO T 283.
• Automatic vacuum regulation reduces the need for constant operator adjustment and can improve repeatability between technicians.
• Optional shaker-frequency and acceleration monitoring helps identify vibration conditions that could damage asphalt specimens.
• Stored test records and USB export make it easier to review procedures and share documentation.
• A compact design can be installed on a benchtop or wall and used with compatible flask or metal-container setups.
• Integrated result-entry and calculation functions can streamline theoretical maximum specific gravity reporting.

Included Items

AutoRice controller, wall-mount bracket and operator manual, per HMA listing. Optional shaker-frequency sensor is not included.

Lab Manager's Tip

Verify the controller voltage and compatibility with the vacuum pump and shaker before installation. For AASHTO T 209/ASTM D2041, confirm the specified vacuum pressure and hold time, and do not assume the optional frequency sensor is supplied. For AASHTO T 283, use the method-specific saturation requirements.

Typical Applications

Asphalt Rice testing, theoretical maximum specific gravity, asphalt moisture-susceptibility preparation, DOT asphalt laboratories and test automation.
