A unique construction machine for compacting the soil base of roads to a depth of up to 3 m has been developed at the South Ural State University (SUSU, Chelyabinsk). This was announced by Marat Asfandiyarov, Associate Professor of the Department of Hydraulics and Hydropneumatic Systems of the university.
According to our calculations, thanks to this machine, roads will meet the requirements of 25 years without major repairs.
According to Asfandiyarov, potholes and ruts quickly appear on Russian roads. Road workers usually use rollers, but this technique does not compact the soil sufficiently.
SUSU's development is a cone-shaped metal superstructure for excavators. Its rotation is provided by a hydraulic motor.
The excavator lowers the device, its cone wedges the soil and compacts it in all directions along the entire depth of penetration of the working body.
Scientists conducted experiments on various soils, including sandy loam, sand and clay. The device has proven the stated characteristics. The developers have already received a patent for the machine and are looking for production partners.
