This instrument is suitable for determining and evaluating the interlayer bond shear strength between surface treatments, sealing coats, tack coats, prime coats, and waterproofing layers and asphalt layers, cement concrete layers, highway asphalt pavement engineering, and concrete bridge deck asphalt pavement engineering, as well as the direct interlayer shear strength and oblique shear strength of bridge decks and other two different materials.

Structural layer material strength shear tester

Model:LJLMF-1

I. Product Introduction

This instrument is suitable for determining and evaluating the interlayer bond shear strength between surface treatments, sealing coats, tack coats, prime coats, and waterproofing layers and asphalt layers, cement concrete layers, highway asphalt pavement engineering, and concrete bridge deck asphalt pavement engineering, as well as the direct interlayer shear strength and oblique shear strength of bridge decks and other two different materials. It can also determine the direct or oblique shear strength of structural layer-bonding layer-structural layer.

This instrument is an automatic data acquisition device for shear force and deformation displacement, developed and manufactured using digital display sensor technology. Shear force accuracy is 1N. It automatically displays the peak test value, making readings more accurate and intuitive.

II. Applicable Standards

ISO 17892-10:2018

ASTM D3080/D3080M-23

III. Structural Features

1. The LCD data acquisition unit automatically acquires, saves, and displays shear force and displacement, prints the load data, and saves 70 sets of data.

2. The loading speed is uniform and stable.

3. The shear disc is easy and quick to install.

IV. Main Features

1. The entire test is automatically controlled and tested by the instrument, eliminating various human errors.

2. It is equipped with an automatic overpressure protection function, which will automatically stop pressurizing the instrument and prevent damage due to overpressure.

3. Can print test peak values and deformation.

4. The loading and unloading of the instrument are automatically controlled by the instrument.

5. The display uses a dedicated chip, eliminating display flickering during the test.

6. Date and time are added to the printing.
