Autorice Automatic Rice Testing Control System

AutoRice Automatic Rice Testing Control System

The Ultimate Solution for Maximum Specific Gravity and Saturated Surface Dry (SSD) Testing

The InstroTek AutoRice is a state-of-the-art automatic control system designed to revolutionize how laboratories perform Maximum Specific Gravity (Rice) tests. This innovative device gives technicians the ability to conduct highly accurate and repeatable tests, such as AASHTO T209 and ASTM D2041, with just the push of a button.

By precisely controlling and monitoring all critical test parameters—including vacuum pressure, vacuum duration, and shaker vibration frequency—AutoRice eliminates the common variables and operator errors that can compromise test results. This automation ensures unparalleled consistency and reliability, whether you're performing routine quality control or comparing results across different labs.

In addition to Rice testing, the AutoRice system automates the vacuum saturation process required for AASHTO T283 (Standard Method of Test for Resistance of Compacted Asphalt Mixtures to Moisture-Induced Damage). This dual functionality makes it an indispensable tool for any modern asphalt lab.

How It Works

The AutoRice unit seamlessly integrates with your existing setup, including glass flasks or metal pycnometers. When a test is initiated, the system automatically starts the vacuum pump, precisely regulates the pressure to the required level, controls the vacuum time, and constantly monitors the shaker's frequency and acceleration. This monitoring is a key feature, as it prevents the stripping of asphalt binder from the aggregate, a common issue that can lead to inaccurate results.

All test data, including vacuum pressure, time, shaker frequency, and acceleration, is automatically logged. This information can be easily downloaded via a USB port, allowing for thorough review, documentation, and sharing to ensure complete compliance with testing standards.
