It can also be used to determine the bond strength of structure layer-adhesive layer-structure layer.

LHLDY-0362 Coarse Aggregate Flow Time Tester

This instrument is used to determine the time required for a certain volume of coarse aggregate to pass through a fixed size opening, indirectly evaluating the angularity of the coarse aggregate. This method is applicable to the angularity determination of coarse aggregate with a nominal maximum size of 9'~19mm.

LHSL-326E Expansion Joint Rubber Seal Strip Clamping Performance Testing Machine

The Microcomputer Controlled Electronic Tensile Testing Machine, specifically designed by Beijing Lanhang Zhongke Measurement and Control Technology Research Institute for rubber sealing strips in highway bridge expansion joints. The computer system, through a fully digital controller, controls the rotation of a high-precision stepping motor via a speed control system. After deceleration by the deceleration system, it drives the movement of the moving crossbeam via a precision ball screw pair, completing the repeated tensile mechanical performance test of the sample. It is suitable for rubber sealing strip performance testing in highway bridges and other applications. The equipment meets the requirements of JT/T326-2016 "General Technical Conditions for Highway Bridge Expansion Joints".
