PRACTICE TO MONITOR MOTOR ROAD Russian patent published in 2004 - IPC

FIELD: monitoring of medium class automobile roads with gravel, asphalt-concrete and other pavements. SUBSTANCE: practice to monitor motor road includes leveling of route points from reference marks of altitude network, determination of marks of points of pavement by measurement of difference in level between them and nearest reference mark. Multiple following of motor road is conducted by measurement and geodetic comparison of marks of pavement of roadway with reference marks on engineering structures and natural objects located along motor road. Marks of pavement surface with regard to reference marks are found instrumentally directly from pavement proper with the aid of several theodolites mounted on motor vehicle traveling over roadway outside of its deformation and displacement points by means of trigonometric leveling. Displacements and deformations in broken points of pavement, engineering structures and natural objects, poor quality reference marks located along motor road included are measured with regard to non-abnormal points of pavement invariable by destruction. EFFECT: enhanced productivity of practice thanks to mechanization of operations with mastery survey of pavement and engineering structures on motor road, diminished time of accomplishment of these operations. 3 cl, 7 dwg
