Automatic CBR Test Machine

UTS-0856.ACPR Automatic CBR Test Machine for Laboratory Applications

The UTS-0856.ACPR Automatic CBR Test Machine is an advanced solution for laboratory evaluation of the California Bearing Ratio (CBR) for road sub-bases, subgrades, and cohesive materials with particle sizes under 19 mm. Compliant with international standards such as EN 13286-47, ASTM D1883, and AASHTO T193, it ensures precise and reliable results for a wide range of soil testing applications.

Key Features

• Robust Design: Equipped with a durable two-column frame and an adjustable crossbeam driven by a 50 kN electromechanical ram.
• Accurate Measurements: Features a 50 kN load cell, a linear potentiometric displacement transducer (25 mm x 0.001 mm), and a penetration piston for precise data collection.
• U-Touch PRO Control Unit: Ensures seamless operation with real-time data display, programmable settings, and compliance with various testing standards. The control unit features an intuitive touchscreen interface and can operate as a standalone system or integrate with a PC via the USOFT-0856 software.
• Versatile Testing: Performs tests according to BS, EN, ASTM, and AASHTO standards, with closed-loop PID control for consistent loading rates and automatic calculations of corrected CBR values at 2.5 mm and 5 mm penetration.
• User-Friendly Interface: Intuitive menu options, real-time graph displays, and remote control capabilities enhance usability and convenience.
