AI Technical Summary
The fixed wheel track of existing rutting test machines results in a small testing area for the overall performance of asphalt mixtures, which cannot fully reflect the true performance of the mixtures.
A wheel track adjustment mechanism for a rut testing machine was designed. Through the combination of a screw, an electric guide rail, a mounting plate, and an adjustment mechanism, the wheel track can be flexibly adjusted. The application of a threaded sleeve, an electric telescopic rod, and a scraper ensures the adjustability of the wheel path and the cleaning effect.
The testing area has been expanded, enabling testing of more areas of asphalt mixtures, resulting in more comprehensive data that better reflects the overall performance of the mixture.
