Effective equipment and technology for building highways

[摘要] Modern road building machines at a high level of mechanization do not meet the increased quality indicators of building highways. One of the main reasons for such poor quality is the lack of compaction of all the structural layers of the road pavement. The existing technology of compacting road-building materials is based on compression deformations, a significant portion of the air remains in the volume of the compacted material and leads to the formation of uneven surfaces (wheel tracks, transverse waves). The new technology of the compaction of road-building materials is based on shear deformations and compression deformation, thus creating a dense, rigid and unchangeable material structure. The article considers the peculiarities of the technology of laying road-building materials and proposes a technical solution for obtaining high-density structures from composite materials. It presents a comparison of the existing and the new technology of compacting road-building materials. The technical solutions of the new devices of the machines' working elements (new equipment and technology) provide a higher coefficient of compaction for various road-building materials.
