A method of operating a road service

 

(57) Abstract:

The invention relates to the maintenance of roads and can be applied to ensure full utilization of the strength of the resource materials of the pavement, the elimination of coleoptere, improve the smoothness and safety due to uniform wear across the width. The method of operation of a pavement is to ensure its uniform wear by the orientation of the wheels of the car through the lanes of the forward roadway by periodic offset on minakata strip. The new method is that the width of the roadway to reduce the width of the wheels of the estimated vehicle with the formation of temporarily unused to traffic backing strip. Backup band in the spring can be placed on the South side of the pavement. The technical result achieved by the present invention is to simplify the method of operation of the pavement, as well as in reducing the cost of its implementation. 1 C.p. f-crystals, 3 ill.

The invention relates to the maintenance of roads and can be applied to ensure full utilization of the strength of the resource materials of the pavement, the elimination of celeabrate the method of operation of the pavement, bringing her uniform wear by the orientation of the wheels of the vehicle to roll bands [1].

The disadvantage of this method include the difficulty of its implementation, requiring the creation of new vehicles and the need to create a fundamentally new, more expensive technologies of construction and repair of roads.

Also known a method of operating a pavement consisting update its uniform wear by the orientation of the wheels of the car through the lanes of the forward roadway by periodic offset on minakata strip by changing the position of the marking lines on the carriageway width [2].

The disadvantage of this method is the need to increase the width of the roadway, which can only be done by the repair or reconstruction of the road. These works are relatively rare, and with a shortage of funds may not be carried out for decades, which leads the road to the catastrophic state. The need for repair or reconstruction in the implementation of this method requires an increase in capital expenditures, which, in its acrania known way.

The objective of the invention is to simplify the known method and reduce the cost of its implementation.

The problem is solved in that during the implementation of the known method the width of the carriageway is reduced at least to the width of the wheels of the estimated vehicle with the formation of temporarily unused to traffic backing strip, and this strip of spring place predominantly on the South side of the pavement.

The invention is illustrated by drawings.

In Fig. 1 schematically shows the transverse profile of the pavement two-lane road with a backup band conditionally on the right of Fig. 2 - conditionally to the left of the lanes of traffic, and Fig. 3 shows the same profile in the spring time.

In the drawings, the following notation is used: 1 - roadway, having in the upper part of the width A; 2 - conditionally on the left edge; 3 - fortified part of the roadway width B, with a solid floor; 4 - the fortified part of the roadway width G having a solid floor and used as a backing strip; 5 - position rear axle of the vehicle when driving; 6 - conditionally right shoulder; 7 - axis, the dashed line once avego ground; 10 - thawed soil.

The proposed method is implemented as follows.

To have a satisfactory condition of the road, with a total width B of the roadway, causing the centerline of the marking 7 is offset from the center and with the formation of the backing strip 4 having a width equal to or greater than the maximum width of the estimated wheel of the vehicle so that the remaining width of the roadway can accommodate at least two lanes for safe movement of vehicles. Backing strip 4 is separated from the main lanes by a solid line markings or broken line marking. In the latter case, establish mandatory signs, recommending that the driver of the vehicle not to use the backup band for the primary mode of movement. So get the offset of the bands forward towards one of the edges (e.g., in the direction of the curb 2 - see Fig. 1) on minakata strip.

If necessary and if available opportunities limit the speed of traffic on marked above method section of road to improve traffic safety.

After a definite time or after the appearance of the first signs is ini markup then put new lines offset in the direction opposite to the curb (e.g., in the direction of the curb 7 - see Fig. 2), thus placing new band forward.

On a multi-lane road reserve part 4 can be made so that the transfer roll bands in one direction and can be performed repeatedly. For example, if the width of the back portion 4 is equal to 1.2 m (the distance between the light traces the rear wheels settlement of the truck), and the displacement step - 0.4 m, with 5 - 8 years length of service band forward in a satisfactory condition, the service life of the pavement in this state will be approximately 15 years, significantly delaying thus the need for significant repairs and reducing the total present value of road maintenance. During a long period of time back portion 4 can serve as a safe lane for uniaxial transport, and can also be used in emergency situations and for transportation of oversized cargo.

In the operation sections narrow roads with high embankment of the road in Northern marshland, raspolojennye it is desirable to produce so so in the spring backing strip 4 was located on the South side (see Fig. 3). In this case, at the beginning of the warm period thawing of the soil, accompanied by his sharp weakening occurs first from the South, i.e. from the side of the backing strip 4, and some time does not affect the operating bands of the roll, the ground which is still in solid frozen state. This increases the lifetime of the road in winter condition, when it can move heavy vehicles.

Currently in Russia there is already a huge network of mostly two-lane paved roads (mainly regional or district level), which gradually decline due to the lack of funds for maintenance in operational condition. For example, in the Omsk region due to the lack of funds annually repaired 100 km of roads, while according to the standards necessary to repair 1000 km, which resulted in many roads, such as highway M51 on the site Omsk-Barabinsk (350 km), came into complete disrepair.

At the same time, the proposed method can achieve the same effect as in the prototype, but the operation of roads without providercomcast roads due to their uniform wear.

In particular, the application of the proposed method in the shortest possible time to stop the destruction of the Russian regional roads and district roads with minimum expenses on their maintenance and repair and reconstruction.
