The Asphalt Mixture Closed Triaxial Test Apparatus is a laboratory device used to evaluate the shear strength, high-temperature stability, and mechanical properties of asphalt mixtures under controlled temperature and confining pressure. It simulates real pavement stress conditions through triaxial loading and is widely used in highway engineering research and asphalt mixture performance testing.

Asphalt Mixture Closed Triaxial Testing Equipment

Model:TD0718-2

I. Product Introduction

The Asphalt Mixture Closed Triaxial Test Apparatus is developed and manufactured by Hebei Tianqixingzi Inspection Equipment Co., Ltd., in accordance with the Ministry of Transport of the People’s Republic of China industry standard T/CHES 29-2019 “Test Specification for Coarse Grained Soils,” specifically the triaxial compression test method.

This equipment adopts servo motor drive technology, automatic control technology, high-precision sensing technology, and a computer-based data acquisition system, forming a new generation of asphalt mixture triaxial compression testing system.

Compared with traditional microcomputer-controlled triaxial testing systems, this equipment offers the following advantages:

Easier operation；

Higher testing accuracy；

Higher level of automation；

Expandable for multiple test functions.

The system supports full-process automatic control, integrating loading, data acquisition, and result analysis into one platform. It is an advanced testing device for evaluating the mechanical properties of asphalt mixtures in China.

This equipment is mainly used to determine the shear performance parameters of asphalt mixtures under specified temperature and loading conditions, in order to evaluate their high-temperature stability and structural strength.

The standard specimen size is Φ100 mm × 200 mm, and the typical test temperatures are:60°C (for petroleum asphalt)；38°C (for coal tar asphalt)
