ROAD STRUCTURE ON LOOSE GROUND Russian patent published in 1998 - IPC

FIELD: road building technology. SUBSTANCE: this relates to design and construction of road pavements, bases, and earth bed and can be used in building of motor roads, airfield runways, sites for various machinery, etc. Road structure on loose ground has underlying base layer, alternating low-strength layers of larger thickness, and more stronger layers of less thickness, pavement, and side faces. Pavement, side faces, underlying layer, and thin layers of base are made of material of equal strength. Pavement and underlying layer are of equal thickness. Width of underlying layer is larger than thickness of pavement. Underlying layers of base relate to each other with respect to thickness within limits of 1:10-1:15 and respectively with their strength within limits of 10:-15:1. EFFECT: higher efficiency. 1 dwg
