The Asphalt Mixture Cylindrical Uniaxial Compression Testing Machine is designed to determine the compressive strength and deformation behavior of cylindrical asphalt mixture specimens under uniaxial loading conditions. It is widely used in laboratory testing to evaluate the mechanical properties, structural stability, and load-bearing performance of asphalt mixtures in road engineering.

Asphalt Mixture Uniaxial Compression Tester

Model:TD713-2

I. Product Introduction:

This equipment is applicable to JTG E20 "Test Procedures for Asphalt-Based Asphalt Mixtures for Highway Engineering" (T0713-2000, T0715-2025, and T0716-2025). It also references international standards such as AASHTO T322, ASTM D1074, and EN 12697 series.

This testing machine adopts an integrated design of main unit and control system, and features a dual-sensor design with a servo system. It can precisely control any loading rate. In addition to performing common mechanical tests on asphalt mixtures, it can also be used with various instrument accessories to determine the unconfined compressive strength, indirect tensile strength (splitting test), and bearing ratio test (including immersion swelling measurement) of various geotechnical specimens. It can also be used to determine the thermal stability and anti-plastic flow properties of asphalt mixtures—stability and flow value (Marshall test)—as well as many other tests that require the application of vertical loads.
