Throughout the entire transition curve 4, the transverse profile is made one-sided, varying from a slope equal to the slope of the carriageway on the straight section 11 to a slope 6 of the main turn. 1 з, п, ф-л, I Il. i (lu

Description

The invention relates to road construction and can be used. Called when designing a road at the rounding.

The purpose of the invention is to increase traffic safety.

The drawing shows a diagram of an autonomous mobile road on a curve, a general view, and transverse profiles along sections.

The road profile includes the outer 1 and inner 2 half of the carriageway with the corresponding transverse slopes 3, which change before the beginning of the transition curves 4 from the normal slope 5 of the outer half of the carriageway to the inclination of the inner half of the carriageway at the beginning of the transition curve 4 and on the route , the transition curve from the slope of the inner half of the 2 carriageway at the beginning of the transition curve 4 to the slope of the 6. main turns 1 at the end of the carriageway, with 4 slopes changing throughout the corresponding transition curves, Leaning to the edges of the carriageway and the image of a skinny two additional turn 7, distilled 8 additional turn. Throughout each transition curve 4, the transverse profile is made sloping, varying from a slope equal to the slope of the carriageway on the straight section 9 to slope 6 of the main turn,
