Motor road coated by boards and method for its operation, board for road coverage Motor road with coverage by rectangular boards comprises boards, on the surface of each of which perpendicularly to the longitudinal axis of the road there is a groove, the cross section of which at the side of the producing board is limited with a section of a vertical straight line, and at the other side it is limited also with a section of an inclined straight line. The method of motor road operation consists in the fact that vehicles are moved along the motor road considered above. The applicable rectangular board for formation of the road surface differs by the fact that it is used to form the road surface of the proposed motor road. |

Elastic 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) Invention 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 In 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 Invention 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 base sides of the truncated pyramids are smaller than the sides of the rectangular parallelepipeds with value equal to the minimum diameter of the curved circle of the cable. The height of the truncated pyramids is less than or equal to the height of the rectangular parallelepipeds. The preferred dimensions of the blocks are 400×400×300 mm. Together with provision of effective installation and high service characteristics, the proposed universal flexible protective concrete quill considerably lowers injury cases among pedestrians when used as topping for pavements. |

Paving panel, paving panel laying method and chamber for above method realization Paving panel comprises separate members connected one to another so that joints between the members define polygonal line. Panel comprises bar members adjoining one another by side surfaces and having upper surfaces, which form common horizontal flat panel surface. Air-tight film is adhered to the upper surface to provide panel rigidity enough for panel engagement with the use of air pressure, panel laying and connection to adjacent panels. Side panel surfaces are provided with alternating extensions and depressions. Method of panel laying involves installing vacuum chamber on panel surface with the use of lifting mechanism so that lower wall of vacuum chamber is fixed and upper wall thereof rests upon support; releasing lower chamber wall and fixing upper wall thereof; creating vacuum in chamber by moving fixed upper wall in upward direction; performing panel engagement with the use of vacuum; moving the panel; installing the panel on bed; joining side surfaces of adjacent panels by means of extensions and depressions; releasing upper chamber wall and lowering thereof by chamber gravity; increasing pressure in vacuum chamber; fixing lower base of vacuum chamber and removing the chamber from laid panel. Vacuum chamber for above method realization comprises sealed body having corrugated elastic walls, which permit chamber volume change and are connected to upper chamber wall and to chamber base located in lower chamber part in air-tight manner. The walls are provided with distance through frames arranged one over another. The body also has outlet valve installed in upper wall orifice. Chamber base is made as perforated plate. Upper base side has support, which is brought into contact with upper wall of the chamber installed in collapsed state when vacuum is created in the chamber. Delimiters are located on lower base side and provide air space between the base and panel to be moved. Base dimensions correspond to that of paving panel. |
