The calibration of the universal testing machine needs to verify the accuracy of the system instruments responsible for obtaining force and displacement measurements.

Density meter is abbreviated as liquid density tester, which is an instrument for measuring density value. The common density meter is a desktop electronic density meter

Automatic binder extractors are used for the analysis of asphalt mixtures using perchloroethylene or tetrachloroethylene solvents. The following is an introduction to the common failures and solutions of automatic binder extractors.

A heavy weight deflectometer is used to measure the deflection of airport runway or normal pavement.

Asphalt testing equipment provides the ability to design and test paving materials for use on roads, bridges, or airport runways. Asphalt testing equipment also performs pavement testing of highways and airport runways to ensure compliance with quality and performance specifications.

Asphalt binder tester is used to determine the asphalt binder content of hot mix asphalt (HMA). Asphalt binder content affects many elements of HMA mix performance, such as strength, durability, stiffness, rutting, and wet damage.
