Asphalt Mix Tester

The GCTS Asphalt Mix Tester is a high-performance system designed for precise, automated testing of balanced asphalt mix designs. With a load capacity of 20 kN, 100 mm stroke, and a highly accurate ±20 kN load cell, it ensures reliable results for various ASTM, AASHTO, and EN standards. Its closed-loop feedback system provides exceptional control of test rates, delivering consistent, accurate data even in extended tests. The advanced 24-bit resolution and 1,000 Hz simultaneous sampling rate offer superior data accuracy compared to lower-resolution systems, ensuring precise test outcomes.

This tester also integrates seamlessly with the gTest app, enabling remote monitoring, control, and report generation from any location—enhancing productivity and reducing downtime. Its versatility makes it suitable for research labs and industrial use, supporting multiple asphalt testing methods such as Marshall Stability, IDT Strength, and Semi-Circular Bend (SCB) testing. With superior control, flexibility, and ease of use, the GCTS Asphalt Mix Tester is a reliable, advanced solution for modern asphalt testing needs.
