Asphalt fracture tester (direct tensile method)

This instrumentAsphalt fracture tester (direct tensile method)According to the industry standards of the People's Republic of ChinaJTG E20-2011According to the requirements specified in T 0629-2011 "Asphalt Fracture Performance Test (Direct Tensile Method)" of the "Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering", the direct tensile test method is used to detect the failure strain and stress performance of asphalt.

This instrumentAsphalt fracture tester (direct tensile method)Suitable for the fracture performance test of asphalt materials after the original asphalt, asphalt film oven test (RTFOT), and asphalt pressure aging container aging (PAV). It is an ideal asphalt fracture performance testing instrument for various asphalt production enterprises, highway pavement construction enterprises, testing units, relevant research institutes, and colleges and universities.

1、 Main technical features

1. Desktop structure, microcontroller control, stepper motor drive, color touch screen operation, injected with intelligent control elements.

2. Using a single-chip microprocessor as the main controller to achieveIntelligent and automated testing process for asphalt fracture performance.

3. Adopting an 800 × 480 color LCD touch screen, the input and output of experimental information are completed through the touch screen.
