Abstract

The invention relates to the field of construction and can be used to strengthen roadsides of roads with rigid and non-rigid pavement.

The technical problem to which the proposed invention is directed is to improve the convenience and safety of traffic on roads with cement concrete, reinforced concrete and asphalt concrete coatings due to equal strength reinforcement of the edge and stopping strips and the device of the upper layers of bonded materials to ensure the same coefficient of adhesion on the roadway , regional fortification and stopping bands.

This problem is solved by the fact that instead of the stop strip of the curb, a noise strip is arranged that has a smaller width, but to ensure convenience and traffic safety it is arranged from the same material as the carriageway or another, with approximately the same adhesion coefficient and has a coarse surface with a height of protrusions of more than 6.0 mm. When a vehicle wheel hits a given lane, an additional loud noise is created that acts on the auditory senses of the driver. Noise warns the driver about driving outside the carriageway and the need to return to the lane.

Description

The invention relates to the field of construction and can be used to strengthen roadsides of roads with rigid and non-rigid pavement.

Known construction of reinforcing shoulders, arranged in the form of trapezoidal or rectangles on the ground subgrade in one or two layers. The design with a reinforced stop strip with disconnected materials and with an edge reinforcement strip made of improved cover is operable in different weather and climate conditions. The disadvantage of this design is the poor protection of the subgrade from destruction by surface waters and the low availability of traffic safety conditions, since the construction of roadside reinforcement with unequal reinforcement of the edge and stop bands does not provide the same adhesion coefficient.

These roadside constructions are presented in the Construction Catalog. Part 3. Knots, constructions. Series 3.503-71. Road clothes of public roads. Materials for designing ”on p.5 and 22, as well as in the technical guidelines for strengthening roadsides (BCH 39-79) on p.5.

The technical problem to which the proposed invention is directed is to increase the convenience and safety of traffic on roads with cement concrete, reinforced concrete and asphalt concrete coatings due to equal strength reinforcement of the edge and stopping strips and the device of the upper layers of bonded materials to ensure the same coefficient of adhesion on the roadway , regional fortification and stopping bands.

This problem is solved by the fact that instead of the stop strip of the curb, a noise strip is arranged, which has a smaller width, but to ensure convenience and safety of movement, it is arranged from the same material,

as the roadway or another, approximately, with the same coefficient of adhesion and has a coarse surface with a height of protrusions of more than 6.0 mm. When a vehicle wheel runs over this lane, an additional loud noise is created that affects the auditory sensory organs of the driver. Noise warns the driver about driving outside the carriageway and the need to return to the lane.

The invention is illustrated in the drawing, where figure 1 shows a transverse profile of a reinforced shoulder.

The positions in the drawings mean:

1 - an alignment strip;

2 - noise band;

3 - the underlying pillow;

4 - regional reinforcing strip;

5 - carriageway.

An example of a roadside reinforcement design.

The construction of reinforcing shoulders includes an underlying pillow, an edge reinforcing, noise and surfacing stripes. On the subgrade, an underlying pillow is arranged to the width of the edge and noise bands for their equal strength reinforcement.

The side strip for all categories of roads along the entire width (0.2 m) is strengthened by sodding or sowing of grasses. The regional reinforcing strip, made of the same road-building material as the carriageway, has a width of 0.75 m for roads of categories I and II, and 0.5 m for roads of categories III and IV. A noise strip is arranged for roads I and II categories up to 1.8 m wide, for the III category road - up to 1.3 m, for the IV category - up to 0.8 m.

An example implementation of the proposed invention is reflected in the technology of the device and the construction of the curb:

- ground leveling of the subgrade;

- compaction of the bottom of the trough;

- delivery, leveling, profiling and sealing of the underlying pillow with a thickness of at least 7 cm;

- the device of the regional reinforcing strip of roadway material with the same thickness;

- device noise band;

- dumping of the fertile layer or laying of turf on a surfing strip 0.2 m wide.

For the device of the noise band using the following materials:

- cement concrete;

- asphalt concrete of various grades;

- black crushed stone;

- crushed stone and gravel materials treated with a binder.

The device of the noise strip on monolithic cement concrete is arranged by cutting diagonal radial grooves, and on precast cement concrete slabs (tiles), a large roughness is arranged during manufacture.

The arrangement of noise strips should be made in the form of a single layer of surface treatment, by embedding crushed stone, laying coarse asphalt concrete, noise wear mats, etc.

Claims (1)

The construction of the roadside of the road, consisting of a regional reinforcing and surfacing strips, characterized in that instead of a stop, a noise strip is arranged, the coating of which is made of asphalt concrete, cement concrete or another mixture with a coarse surface of protrusions more than 6 mm high, which ensures the same adhesion coefficient to the regional reinforcing a strip and a smaller width due to equal strength strengthening of the edge and noise bands.
