Description

Technical Field

[0001] The invention relates to the fields of road construction and material testing, and in particular to an asphalt mixture rotary compactor. Background Art

[0002] Asphalt Mixture Gyratory Compactor is a device specially designed to simulate and evaluate the compaction effect of asphalt mixture in road construction. This type of instrument helps engineers predict and verify the performance of the materials used in actual applications by simulating the compaction effect of vehicles on the road.

[0003] Existing asphalt mixture gyratory compactors usually include a fixed compaction unit that can apply vertical pressure to the asphalt mixture placed in it. These devices apply pressure evenly to the mixture through electric or hydraulic machinery to simulate the compaction effect of heavy vehicles driving on the road surface. In effect, these devices can evaluate the compaction, stability and load-bearing capacity of the mixture under specific conditions, providing basic data for road design and construction.

[0004] Although existing equipment can basically complete compaction test tasks, it usually lacks flexibility and is difficult to simulate the actual compaction environment under different road slopes or changing conditions. In addition, existing equipment mostly relies on operators to manually load and unload materials, which increases the labor intensity and complexity of operations. These limitations make the equipment inadequate in performing multi-condition simulations and reducing manpower dependence, thus affecting the efficiency and extensiveness of the test. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an asphalt mixture rotary compactor, which enhances the flexibility and automation level of the equipment by introducing an adjustable compaction angle mechanism.
