ROAD CROSS-SECTION ON SLOPES AND RISES Russian patent published in 2008 - IPC E01C1/00 

FIELD: transport.

SUBSTANCE: invention relates to road construction, particularly to designing and constructing the motor rods, primarily to selection of the road cross-section on rises and slopes. The motor road cross-section on rise and slopes is composed of, at least two roadway driving lanes, roadsides and slopes and comprises a dual-slope surface arranged on every driving lave and on roadsides with slopes. Note here that the dual-slope surface slopes, within every driving lane, are directed from the axis of every driving lane towards their edges, while the slopes of roadsides are directed from the grade level edge towards the roadway edge and from the grade level edge towards the road foot along the slope. The aforesaid dual-slope surfaces, within the limits of every driving lane, are furnished with lateral grooves arranged between the driving lane axis and its edge at an angle to the surface lengthwise slope.

EFFECT: higher traffic safety, reduced negative effects on environments, motor road longer life.
