Abstract

FIELD: construction.

SUBSTANCE: motor road consists of ground of soil, a layer of sand, a layer of rubble, asphalt concrete coat and reinforcing strips. At the same time, longitudinal reinforced concrete beams are located on the piles driven into the ground of the soil, each row of which is distanced from the other two rows, respectively by 0.5 m and 1.5 m.

EFFECT: increase in the strength of the asphalt concrete layer by reducing the pressure of the wheels of cars on it.

Description

The invention relates to the construction of roads.

Known road, consisting of the soil of the roadbed, a layer of sand, a layer of crushed stone, asphalt concrete pavement and fortification strips (V.F. Babkov, O.V. Andreev. Designing of roads. Volume 1. Moscow, pp. 29, 295-297 )

However, on this highway, the asphalt concrete layer is destroyed by the pressure of the wheels of the cars.

The technical result of the invention is to increase the strength of the asphalt concrete layer by reducing the pressure on it of the wheels of automobiles.

The specified technical result is achieved by the fact that the road consists of soil of the roadbed, a layer of sand, a layer of crushed stone, asphalt concrete pavement and reinforcement strips, while longitudinal reinforced concrete beams are located on piles driven into the soil of the roadbed, each row of which is separated from the other two rows 0.5 m and 1.5 m respectively.

In FIG. 1 shows a highway, a top view.

In FIG. 2 shows a motorway, cross section.

In FIG. 3 shows a highway, a longitudinal section.

The road has the following structure. Reinforced concrete piles 2 are driven into the soil of the landbed 1. On the soil of the landbed there is a sand layer 3. On the sand layer 3 there is a layer of crushed stone 4. On piles 2 and a layer of crushed stone 4 longitudinal reinforced concrete beams 5. On the layer of crushed stone 4 are reinforced strips 6. Between the reinforcing strips 6 and the reinforced concrete beams 5 on the layer of crushed stone 4 there is an asphalt concrete pavement 7. The first row of 8 reinforced concrete beams is separated from the first reinforcing strip 6 by a distance of 0.3 meters. The second row of 9 reinforced concrete beams is 1.5 meters from the first row of 8 reinforced concrete beams. The third row of 10 reinforced concrete beams is separated from the second row of 9 reinforced concrete beams by 0.5 meters. The fourth row of 11 reinforced concrete beams is 1.5 meters from the third row of 10 reinforced concrete beams. The fifth row of 12 reinforced concrete beams is 0.5 meters from the fourth row of 11 reinforced concrete beams. The sixth row of 13 reinforced concrete beams is 1.5 meters away from the fifth row of 12 reinforced concrete beams and 0.3 meters from the second reinforcing strip 6.

The operation of the road is as follows. The highway has markings for each convoy of cars and trucks. The first convoy of cars travels along the first and second rows of 8 and 9 reinforced concrete beams. The second convoy of cars travels along the third and fourth rows of 10 and 11 reinforced concrete beams. The third column of cars travels along the fifth and sixth rows of 12 and 13 reinforced concrete beams. The first convoy of trucks travels along the first and third rows of 8 and 10 reinforced concrete beams. The second column of trucks travels along the fourth and sixth rows of 11 and 13 reinforced concrete beams. Cars on asphalt concrete pavement 7 almost do not drive. Without experiencing much pressure on the wheels of cars, the asphalt concrete pavement will not collapse. The road will be in good condition for a long time.

The use of the highway of the proposed design will allow to obtain the following technical and economic effect. A well-known motorway often needs repair. This increases the cost of its operation. The road of the proposed design for a long time, repair is not required. This will reduce the cost of its operation.

Claims (1)

A road consisting of soil of a roadbed, a layer of sand, a layer of crushed stone, asphalt concrete pavement and reinforcing strips, characterized in that longitudinal reinforced concrete beams are located on piles driven into the soil of the roadbed, each row of which is 0.5 times spaced from the other two rows, respectively m and 1.5 m.
