Airfield slabs of the PAG-14 type are often used in civil engineering. At a relatively affordable price, they have unique performance characteristics. Therefore, PAG-14 is often chosen as an alternative to conventional (road) reinforced concrete products.

It is most expedient to use PAG-14 in the following cases:

- runways for light aircraft

– public roads with heavy traffic

– permanent and temporary access roads

– construction of industrial and storage facilities.

When choosing a suitable type of airfield slabs, one should take into account the maximum allowable load, which for PAG-14 is 50 t/m 2 . It should be noted that this is sufficient in most cases in the construction of roads and industrial facilities.

PAG 14 features and production requirements for such products are regulated by GOST 25912.0-91. This standard states that a heavy type of concrete with a density of more than 2200, but not exceeding 2500 kg/m 3, must be used for production. The tensile strength class of concrete under bending loads must be B btb 3.6 and compressive strength not lower than B25. Its frost resistance for a product intended for operation at temperatures of minus 15 ° C and below must correspond to class F200.

PAG-14 slabs may differ in the fittings used. This is indicated by additional markings. Prestressing reinforcement from steel grades At-IV or A-IV is indicated in the designation by the number IV, and from slightly stronger steel At-V - by the number V. The diameter of the reinforcement used is 14 or 12 mm. In the latter case, index 1 is added to the designation.

An example of decoding the designation:

PAG-14V -1 - airfield plate 14 cm with longitudinal prestressing reinforcement 12 mm, made of At-V steel.

Products with fittings made of steel of class V with a diameter of 14 mm have the best strength characteristics. This is confirmed by GOST-regulated tests for crack resistance during deflection. For PAG-14, the control load during tests for bending tension and compressive strength is 42.2–46.1 kN. In this case, the minimum value corresponds to PAG-14IV-1 products, and the maximum value corresponds to PAG-14V.

Dimensions and weight of airfield plates:

– length 6 m

– width 2 m

– thickness 0.14 m

- weight 4200 kg.

The working (upper) surface of the products has a roughness obtained by processing with nylon brushes. By agreement with the customer, it is possible to manufacture plates with corrugation up to 2 mm deep.

The unique strength and performance parameters of PAG-14 boards, along with the ease of installation and the possibility of repeated use, often make their use in civil engineering economically viable.

PAG-14 slabs are made of reinforced concrete and are intended for the installation of airfield pavements. The PAG marking stands for "aerodrome smooth plate". The number 14 indicates the thickness in centimeters.

PAG boards are suitable not only for airfields, but also for:

• for the construction of autobahns;
• for the improvement of urban roads;
• for creating prefabricated coatings in warehouse and industrial premises.

Airfield slabs PAG-14 are distinguished by their ability to withstand high operating pressure - over 75 tons. That is why they are suitable for installation on runways and highways where heavy equipment moves. Plates have increased frost resistance, they can be installed even in those regions where the air temperature drops to -60°C.

Airfield slabs are manufactured in accordance with GOST 25912.0-91. Heavy concrete is used for their manufacture. Special compounds are added to the concrete solution, thanks to which it is possible to obtain a smooth surface that is resistant to mechanical damage. To increase strength, reinforced concrete structures are reinforced.

For the construction of a runway or road surface, airfield slabs are installed on a sandy base. The next stage is the welding of products using special welded loops. Then the gaps at the junction of the plates are filled with concrete, and a perfectly even coating is obtained.

Characteristics of airfield plates PAG 14

For laying permanent roads for heavy construction equipment, as well as important sites in difficult geodetic and hydrogeological conditions, PAG 14 airfield slabs are used. Since high safety requirements are imposed on the plates of this marking, these plates are made using high-class tension reinforcement and heavy concrete, which successfully withstands increased compression pressure and behaves at low temperatures without any negative impact. The main advantage of PAG 14 is strength, wear resistance and reliability, which determine the possibility of long-term operation. For the construction of roads for vehicles, the characteristics of PAG 14 slabs are more than enough.

Airfield plates PAG 14 manufactured to create durable and reliable runways, construction of permanent and temporary roads, as well as for the arrangement of industrial and storage facilities. The airfield slab is capable of withstanding a workload of up to 75 tons per square meter. Even at an extreme temperature of 60 degrees, the quality characteristics of airfield plates do not deteriorate. Thanks to special additives, the products have a durable surface that can withstand constant mechanical stress and are practically not subject to destruction.

Are made airfield slabs by pouring the concrete mixture into special forms using vibration technology to compact the mass. After crystallization of the concrete mixture, the products are transferred to thermal chambers for final hardening. Ready-made airfield slabs are distinguished by increased strength and durability, increasing the reliability of the entire roadway.

Since the plates were originally intended for arranging airfield strips, there is no doubt about their reliability and durability. Over time, the range of application of airfield slabs expanded and they began to be used as temporary access roads to facilities under construction for convenient delivery of building materials, entry of special equipment and transportation of equipment. When creating an access road, the soil surface is leveled with a bulldozer, a sand cushion is poured and compacted on top, after which reinforced concrete slabs are laid on the cushion.

The airfield slab is a high-quality reinforced concrete product that retains its operational properties for many decades, which allows it to be reused during dismantling. Reuse of reinforced concrete slabs is financially beneficial in the construction of temporary roads, access roads and other small buildings.

Specifications

Airfield slabs have a relief surface, which is achieved by laying diamond-shaped corrugated steel elements on the bottom of the formwork. Additional roughness on the surface of the products is created using special brushes and tarpaulin tapes. The rough surface provides reliable grip on the wheels of any vehicle. The width of airfield plates varies from 140 to 200 mm. Mounting loops are installed on the side faces of the airfield plates. All sheets are equipped with special grooves and metal loops for quick connection during installation. Due to the simple disassembly, the airfield plate can be reused while maintaining the original performance.

Deciphering the marking

Depending on the thickness of the plate, they are divided into PAG-14 (140 mm), PAG-18 (180 mm) and PAG-20 (200 mm).

To decipher the marking, take the airfield plate PAG 18, where:

• PAG- smooth rectangular aerodrome slab
• 18 - plate thickness 180 mm

Other designations:

• At-V- class of fittings used

Airfield slabs are made of heavy concrete class B25 (M350) with the addition of special chemical additives that give the product additional elasticity, frost resistance, heat resistance and strength. The concrete frost resistance criterion corresponds to F200, and the water resistance criterion corresponds to W8. Products are suitable for use in difficult climatic, geological and seismological conditions.

The use of a metal frame makes it possible to improve the quality characteristics of airfield plates and prevent the impact of negative factors. Stressed and unstressed steel bars are used for reinforcement.

Mounting Features

To ensure the duration of the operating period declared by the manufacturer, the airfield plate must be correctly mounted. High-quality installation will ensure resistance to static and dynamic loads. It is strictly forbidden to lay airfield slabs directly on the ground. From the weight of the slab, the soil will begin to change its shape, which will lead to damage to the entire structure.

Before laying the airfield slabs, it is necessary to cultivate the soil: cut off the top layer of soil, level the surface and remove all irregularities. After that, you need to dig a trench about 300 mm deep and cover it with a layer of geotextile, which prevents the growth of grass and prevents the base from washing out. Crushed stone with sand is poured over the geotextile, rammed and watered. To compact the base for the road slab, a vibrating plate or a vibrating roller is used. The preparation of the pillow is considered complete when the surface acquires the necessary evenness for the subsequent laying of reinforced concrete products.

Depending on the terrain, a slope is equipped to drain melt and rainwater. Installation of storm sewer trays is possible. After creating a slope, curb enclosing stones are installed.

After laying the airfield slabs, the reinforcing parts are fastened with a welding machine. In this case, high-quality steel grade AIII is used. All joints are sealed with a special sealing material that can withstand mechanical loads, temperature changes and is resistant to aggressive technical fluids that can leak from equipment.

Quality control

There are a number of indicators that are checked by control loads. These indicators include the strength and resistance of plates to the appearance of cracks; strength of concrete and its raw materials; quality of reinforcement, its brand, quantity and placement; quality of embedded elements and mounting loops; the thickness of the protective layer of concrete up to the reinforcing cage, etc. According to GOST, the sagging on the surface of road slabs should not exceed 15 mm both in depth and in diameter.

A special condition for the suitability of airfield plates for further operation is the presence technical passport (certificate of quality). It indicates all information about the finished product, technical parameters, production date, marking formula, frost resistance and water resistance. In addition, the availability of a technical passport is a prerequisite for the transportation and storage of airfield plates.

Slab PAG-14 (smooth airfield slab) belongs to the category of reinforced concrete slabs for special purposes. It is characterized by exceptional strength, durability, ability to work in conditions of extremely low temperatures and withstand high loads. In addition to its direct purpose - the installation of runway pavements - reinforced concrete slab pag 14 is widely used in other industries. In view of its impeccable performance, it is suitable for multiple use at construction sites, in the construction of temporary roads, car parks, and more.

The main regulatory documents regulating the production technology of plates are:

• GOST 25912.0-91 "Prestressed reinforced concrete slabs PAG for airfield pavements";
• OST 25912.1-91 “Prestressed reinforced concrete slabs PAG-14 for airfield pavements.

Design."

The standards establish requirements for the grade of concrete, reinforcement, geometric dimensions of a reinforced concrete product, tolerances for surface quality, reinforcement method, marking, etc. Compliance of the finished product with regulations is strictly required. All deviations are permissible only within the limits indicated by GOST. The main technical characteristics of the pag 14 slab, the dimensions of the product correspond to the following parameters:

• minimum compressive strength - 29.4 MPa;
• frost resistance - F200;
• weight - 4.2 tons (including fittings 140.7 kg);
• dimensions - 6.0x2.0m, height 0.14m;
• the lower temperature threshold of operation is minus 60°C.

Plate marking provides for an alphanumeric designation separated by a hyphen, for example, PAG-14IV-1, where the abbreviation stands for “airfield smooth plate”, 14 is its thickness in centimeters, IV is a class of longitudinal reinforcement, “1” is an indicator of steel diameter. The presence of the last digit indicates a reinforcement diameter of 12mm, and its absence indicates a diameter of 14mm.

Airfield slabs, as well as all reinforced concrete products, have a metal frame, which is poured with concrete. Metal is designed to absorb tensile loads, while concrete is designed for compressive loads. In order to ensure high strength of the slabs, concrete of class B25 or B30, extra strong steel bars of class AIV-AV and a technology that provides for pre-tensioning of reinforcement are used in the production.

For the manufacture of prestressed plates, special metal molds are used, equipped with end stops, five or six pieces on each side. In the first case, the reinforcement of the reinforced concrete slab pag 14 is made with rods with a diameter of 14 mm, in the second - 12 mm. A new trend in the field of production is the use of thermoelectroforms that do not require additional equipment, such as vibrating tables, steaming chambers. The stands are completely autonomous, equipped with a thermoelement, a thermal blanket, due to which deep heating and steaming occurs. The duration of heat treatment of the product is 8 hours.

Despite the fact that PAG-14 slabs are highly specialized products, they are also in great demand in other areas of activity: road construction, industry, equipment for landfills, large terminal sites, and more. Reinforced concrete products are indispensable in places where high-tonnage vehicles move, as they are distinguished by exceptional reliability and durability. Often they serve as the basis for the installation of tower cranes and other means of mechanization. Airfield plates that were in use are in high demand. This may be the arrangement of temporary entrances to the construction site, earned quarries, the arrangement of pedestrian zones.
