Basic Principle and Application Analysis of Asphalt Wear testing machine

Asphalt is a commonly used material in road construction, and its wear resistance has an important impact on the service life and safety of roads. As a special equipment for evaluating the wear resistance of asphalt, the asphalt wear-resistant testing machine is crucial for the selection of road materials and the control of road construction quality. This article will introduce the principle, application and significance of the asphalt wear-resistant testing machine, and discuss its importance and future development trends in the field of road construction.

Fundamental

The asphalt wear resistance testing machine mainly evaluates the wear resistance of asphalt by simulating the friction process between the wheels and the road surface when the vehicle is driving. Its working principle is to use the rubber wheel or steel wheel in the testing machine to contact the surface of the asphalt sample, apply a certain load and rotation speed, and then evaluate it by measuring the mass loss of the asphalt sample or the wear of the sample surface before and after the test. Wear resistance of asphalt.

Application areas

Asphalt wear-resistant testing machines are widely used in road construction, material research and development and other fields. In road construction, asphalt abrasion resistance testing machines can be used to evaluate the abrasion resistance of different types and ratios of asphalt materials, and guide the selection of road materials and control of construction quality; in the field of material research and development, asphalt abrasion resistance testing machines can It is used to evaluate the wear resistance of new asphalt materials and guide the development and application of new materials.
