Viscous oil layer bonding strength tester

This instrument is designed in accordance with the new standard T 0677 adhesion strength test (shear) and T 0678 adhesion strength test (drawing) of the viscous oil layer in the People's Republic of China industry standard JTG E20 "Highway Engineering Asphalt and Asphalt Mixture Test Regulations" Manufactured, used to determine the interlayer bonding strength between the sealing layer, the adhesive layer, the permeable layer and the waterproof layer and the asphalt mixture. This instrument is a newly developed asphalt mixture testing instrument developed by our company. It is a preferred asphalt mixture interlayer bonding strength testing instrument for various asphalt manufacturers, highways, bridge construction units, and related colleges, universities, and research institutions.

Main technical features

1. It adopts industrial-grade color touch screen control and display, real-time display test data and test curve, and automatically save working parameters.

2. The load pressure is 100kN, which can be widely adapted to the bonding strength test of various relevant specimens.

3. Using LVDT linear displacement sensor, the accuracy can reach 0.01mm in the full range of (0~20) mm.

4. The self-developed software control system records the test process data (at an interval of 20ms) and can export all the data from the U disk, which can be used by scientific research users such as universities, research institutes and other in-depth analysis and research.

5. The test speed, lifting speed and idling speed of the loading motor are steplessly adjustable, which provides convenience for users to do scientific research experiments.

6. The outdoor road test can be converted to indoor completion.

7. It has a USB communication port, which can be connected to a thermal printer to print the test results. For special needs, the network remote communication function can be extended.

8. It has the functions of overload protection, equipment failure warning, etc., with a buzzer sound alarm prompt, and the fault code shows the cause of the failure.

9. The base box is made of stainless steel, which is beautiful, easy to clean and durable.
