HTHY-314 Asphalt Direct Tension Tester

Standards:

AASHTO T369
AASHTO T314
ASTM D6723

Product Introduction

The instrument evaluates the low-temperature cracking resistance of asphalt by measuring the failure stress and failure strain of asphalt. Combined with the test results obtained from the Bending Beam Rheometer (BBR), it provides a comprehensive evaluation of the low-temperature performance of asphalt materials.

Technical Specifications

Product Features

• Controlled and displayed by a laptop computer, the system is easy to operate and provides real-time test curve display.
• Equipped with a high-precision displacement sensor for more accurate displacement measurement.
• The load cell is installed at the fixed end to minimize the influence of friction on test results.
• The loading rate is controlled by a closed-loop control system, ensuring more precise loading performance.
• The cooling system adopts a combined Peltier and refrigeration unit mode, providing rapid cooling. The temperature can be reduced from ambient temperature to -18℃ within 40 minutes, with high temperature control accuracy.
