 Pavement plate / 2433219Elastic layer contains a coarse filler in the form of ball elastic elements, and a bearing layer - a coarse filler in the form of ball non-elastic elements, besides, the bearing and the elastic layers include a ball filler of various diameter, in the bearing layer the ball non-elastic filler is distributed along the section and the length of the plate, according to bending moments present in it. Besides, between the elastic and bearing layers there is a cloth with holes, where the ball elastic filler is installed. According to the invention, in the elastic layer there are reserve elastic zones arranged by inclusion of hollow ball filler into the concrete structure and its enclosure into a continuous elastic-massive structural chain of large-sized and small-sized ball elastic filler. The reinforcement and fixation element is an elastic net with square holes, where the ball elastic filler is installed, besides, the size of the net square side is less than the diameter of the ball elastic filler. At the same time the elastic layer is made with a surface of periodical profile in the form of ledges made of the ball elastic filler. |
 Aerodrome takeoff and landing strip by demchenkov dp (dtls) / 2418906Invention objective is to arrange a takeoff and landing strip, which reduces wear of wheel tyres in high-speed aircrafts that land on it, and developing lower landing optional braking loads. The takeoff and landing strip, preferably made of cement and concrete, has a landing and a controlled braking sections. The novelty is the fact that surface of its landing area has a lower friction ratio (FR) - paired with aircraft wheel tyres compared to the controlled-braking section, at the same time between the first and second ones there is a transition section arranged, FR of surface in which increases from the first to the second until it equals the FR. |
 Method and design of motor road construction and repair with hard rut-protected coating / 2418128In method of motor road construction and repair with hard rut-protected coating, rut-protected slabs, solid or with holes, are laid onto the road bed partially filled to a design elevation in an addressed manner, as well as additional slabs made of inert material with reinforcement or without it, which are then filled with the road bed material to the design elevation of the road bed top, onto which the hard coating is laid, and during motor road repair, the road hard surface lane with formed ruts and adjacent sections is cut together with a part of the road bed to the depth of the addressed installation of the rut-protected and additional slabs, after installation of which onto the cut bottom it is filled with the road bed material, on which the hard coating is laid, besides, the rut-protected slabs are made of inert material with reinforcement or without. Design of the motor road with hard rut-protected coating, the rut-protected slabs have fixed width and are laid into the road bed body in an addressed manner at a certain depth from the road surface, at side edges the rut-protected slabs have ledges, and instead of the rut-protected slabs ledges it is possible to use additional slabs, which have dimensions of ledges laid next to the rut-protected slabs and in a staggered order between each other at the distance from 0.1 to 0.3 m. |
 Universal flexible protective concrete quill / 2325474Invention relates to road construction, particularly to construction of pavements, and can as well be used in hydraulic construction. The universal flexible protective concrete quill consists of concrete blocks, joined together one after the other and in rows by flexible cables. In the upper part the blocks are in the form of rectangular parallelepipeds, and in the lower part they are in the form of truncated pyramids with an inclination angle of the edges between 20° and 45°.

The invention relates to road surfaces and can be used in the construction and repair of roads with a firm covering.
Famous road plate (patent RU 2474639 C2, AS 5/06, publ. 10.02.2013, bul. №4). However, the drawback of the road with the specified stove is the high cost of construction.
On the same technical solution stated road stove is the most close to the invention.
Before the invention was given the task of reducing the cost of construction of the road while retaining a high degree of safety.
The technical result of the invention - reducing the cost and terms of construction of roads, extension of the term of its operation.
The technical result is achieved due to the fact that for packing on the basis of the road (next road) apply the road stove with bearing surface, which contains two parts, bearing surface each of which is made with the rise in the direction of travel of the vehicle, and the connection supporting surfaces with each other looks stage, and the height of the receiving side face plate is equal to the height of her giving side.
Under the base plate surface understand its outer upper side.
The drawing shown symbolically road with floor plates, side view.
Solid arrow shows the direction of movement of vehicles.
The road contains a base 1 with plates of 2, 3, 4, 5. The plate 3 is part of the 6 support surface 7 and part 8 support surface 9. Connection supporting surfaces 7 and 9 made in the form of level 10 in height, h. Receiving a lateral side of the plate 3 is the side 11, and giving a lateral side - face 12. The plate 3 is connected to the plate 4 by means of the gap 13. Plate 4 respectively contains part 14 with the bearing surface of 15 and paragraph 16 with the bearing surface of 17, as well as the receiving side 18 and giving the side 19. Support surface 15 and 17 plate 4 are connected through step 20. Height h1 giving side 12 plate 3 is equal to the height h2 host side 18 plate 4, which facilitates the installation of plates on the basis of 1 of the road.
Road plates are used in the following way.
On the prepared surface 1 sequentially, one after another stack road plates 2, 3, 4, 5. However, accepting and giving the lateral sides of plates have the same height, which reduces the complexity of their installation on the basis of 1 on one level and reduces the terms of construction of the road. Plate with a specified reference surface are made in casings on traditional technology. On the basis of the road plates stack on traditionally used technologies with the help of lifting devices.
Road operate as follows. The wheels of the vehicle (not shown) in the process of movement in contact with the supporting surface textures 2, 3, 4, 5 road and interact with them. The presence on the boards 3 and 4, factory fabricated, steps 10 and 20 ensures their strength and increases the life of the road. Thanks steps 10 and 20 increases the force of coupling of wheels of the vehicle with the supporting surface of the plates 2, 3, 4, 5, allowing to increase the start-up speed. Leaving the vehicle on a counter lane creates an uncomfortable environment for driver and passengers, the additional load on the vehicle.
Road stove and support surface, characterized in that it contains two parts, bearing surface each of which is made with the rise in the direction of travel of the vehicle, and the connection supporting surfaces with each other looks stage, and the height of the receiving side face plate is equal to the height of her giving side.
