PROCEDURE CONTROLLING HYDRAULIC AND TEMPERATURE CONDITION OF ROADBED OF MOTOR ROAD ON SECTIONS WITH PRESSURE GROUND WATERS Russian patent published in 2003 - IPC

FIELD: road construction. SUBSTANCE: invention can be employed to diminish destruction of roadbed across sections of roads with pressure ground waters. Novelty of procedure controlling hydraulic and temperature condition of roadbed of motor road across sections with pressure ground waters consists in construction of draining layer in roadbed that includes draining geotextile interlayer. Holes are drilled to depth of bedding of water-bearing horizon of pressure ground waters. Upward current of pressure ground waters in holes is divided into two currents, one current being directed into draining layer and the other current is brought out beyond limits of roadbed. EFFECT: raised bearing capacity of roadbed and pavement by reduction of temperature gradients in them in summer and winter seasons. 1 cl, 1 dwg
