Abstract
The development of transport infrastructure is a priority task for our country with its vast and not fully developed territories. Transport construction requires the use of advanced technologies and the most modern and high-performance construction equipment. The article substantiates the relevance and importance of the process of compaction of road materials in the construction of earth embankments of highways. It is the subgrade that is the supporting engineering structure for the expensive upper layers of the road base and pavement. If the subgrade soils are poorly compacted, this will lead not only to the destruction of the earth embankment itself, but also to the destruction of the upper technological layers located on it, and these are unacceptable losses. Self-propelled road rollers are the main machines that compact the technological layers of the road, ensuring their strength and durability. Various designs and types of road rollers have appeared due to the variety of compacted materials and their properties. To ensure an efficient compaction process, it is necessary to correctly select not only the type of compacting machine, but also its operating modes. A new working body of a road roller capable of regulating contact pressures in an extended range is considered. An experimental sample and a calculation scheme for determining the main parameters are presented. The article provides a developed methodology for substantiating the parameters of a road roller with a new working body for the construction of transport infrastructure. The use of a new design roller and properly selected parameters of its operation will increase the efficiency of construction and reduce the cost of the technological operation of compacting the subgrade layers.
