This equipment is used to determine the shear strength and bond properties between asphalt pavement layers. By simulating shear stress caused by vehicle loads through a ground-pushing horizontal loading method, it can evaluate interlayer bonding, anti-slip capacity, and overall pavement structure performance. It is widely used in highway construction quality control, materials testing, and scientific research.

Asphalt Layer Direct Shear Tester

Model:TDZJ-5

I.Product Introduction

This product is suitable for determining and evaluating the direct interlayer shear strength between surface treatments,seal coats,tack coats,prime coats,and waterproofing layers and asphalt layers,cement concrete layers,bridge decks,and other different materials.

This instrument can determine the direct shear strength of the structural layer-bond layer-structural layer.Developed and manufactured using digital display sensor technology,it automatically acquires shear force and deformation displacement.Shear force accuracy is 0.01 kN.It automatically displays the peak value of the test,providing more accurate and intuitive readings.

II.Structure and Features

1.The LCD data acquisition unit automatically acquires,saves,and displays shear force and displacement;it prints load,displacement,and curves;and saves 30 sets of data.

2.The loading speed is uniform and stable.

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