The Asphalt Mixture Indirect Tensile Tester is used to determine the indirect tensile strength and splitting resistance of asphalt mixtures under specified temperature and loading conditions. It evaluates the cracking resistance and structural performance of asphalt materials and is widely applied in road engineering, pavement material testing, and mix design.

Asphalt Mixture Indirect Tensile Tester

Model:TD716-2

I. Product Introduction

This Asphalt Mixture Indirect Tensile Tester is independently developed and manufactured by Hebei Tianqixingzi Inspection Equipment Co., Ltd.. The equipment complies with JTG 3410-2025 Standard Test Methods of Asphalt and Asphalt Mixture for Highway Engineering (T0716-2025 Indirect Tensile Test of Asphalt Mixtures) and also refers to international standards such as ASTM D6931 and EN 12697-23.

This testing machine is used to determine the mechanical properties of asphalt mixtures under specified temperature and loading rate conditions, either at the stage of splitting failure or within the elastic range. It is also applicable for determining the mechanical design parameters of asphalt mixtures in pavement structural design and evaluating their low-temperature crack resistance performance.
