Technological improvements for compaction of road-building materials

The modern road construction equipment in terms of a high level of mechanization doesn’t conform to the increased road construction quality level. One of the main reasons of poor quality is insufficient compaction of all structural layers of road surface. The paper deals with technical issues of roads quality improvement. The specific features of road materials placement technology are considered. The authors suggest an engineering solution to get high-density structures made of composite materials. The new technology of road materials compaction based on shear deformations is introduced. The engineering solutions of new devices of operating elements of machines ensure a higher factor of compaction of road-building materials.
