Road plates. Buy road slabs from the manufacturer "Anler Road slabs standard sizes

A wide range of types of reinforced concrete products and their forms offered today on the building materials market allows you to quickly solve a large number of tasks related to the arrangement of road surfaces, storage and production areas, as well as paving garden paths.

Advantages and disadvantages of application

The main advantages of using road slabs include:

• simple laying technology, which increases the speed of installation and simplifies construction work while maintaining high quality of the coating;
• relatively low cost of the materials used;
• reducing the cost of excavation and related work;
• high reliability, strength and frost resistance of the coating;
• the possibility of recycling the material after dismantling.

The main disadvantage is the presence of seams that do not allow you to get a perfectly flat surface. However, the use of asphalt as a topcoat or grouting can help overcome this disadvantage and improve the surface quality.

Classification

Road slabs are classified according to their purpose, geometric shape and size in accordance with GOST 21924.0-84. By appointment, they are made for permanent and temporary road surfaces. PAG airfield slabs with increased strength are considered as a separate type of product. The type of products is determined by the marking. If "1" is used as the first digit, then this indicates the use of the material as a permanent coating, and the number 2 means temporary.

According to the geometric shape, road reinforced concrete slabs are divided into:

• rectangular grades P;
• with one or two combined sides - PB, PBB;
• PT - with a flat trapezoidal surface;
• PSh, PShD, PShP, DPSh, PPSh - hexagonal structures and their additional elements.

Rectangular products are the most common, as they are the easiest to manufacture, install and are in the best demand. Their length can be in the range from 1.75 to 6.00 meters, and the width - from 1.00 to 3.75 meters. More details are given in the tables.

Marking examples:

• HDPE 6×2 - with prestressed reinforcement, 6.0 m long and 2.0 m wide;
• HDPE 3 × 1.5 - with prestressed reinforcement, 3.0 × 1.5 meters;
• road slab 2P 30 18 30 - for temporary roads, 3.0 × 1.8 m, designed for an allowable weight load of up to 30 tons;
• 2P30.18-10 - for temporary roads, 3.0 × 1.8 m, designed for an allowable weight load of up to 10 tons.

Other species are marked in a similar way, including data on their purpose, geometric shape and size.

The use of materials for airfield decking in road construction makes it possible to obtain a particularly strong and durable coating with a soft corrugated surface, which will provide better vehicle stability on the road. Reinforced reinforcement and the highest quality concrete are used for manufacturing.

Construction of reinforced concrete slabs

Structurally, the slabs are flat reinforced concrete products with a thickness of 140-240 mm with prestressed or non-stressed reinforcement. For convenient installation, they can have metal loop grips that are hidden in the body of a monolithic structure and do not protrude to the surface of the road surface.

The main building material for manufacturing is concrete, which closes the reinforcing reinforcing structure from adverse atmospheric and mechanical influences. For the manufacture of road slabs, concrete with frost resistance of at least 150 cycles and a density of 2.2-2.5 t/m 3 is used.

In the manufacture of prestressed reinforcing cages, steel reinforcement grades A-5, AT-5 and AT-4 are used. In the case of unstressed structures, reinforcement grades A-1, A-3 and A-3C are used, as well as BP-1 wire with a diameter of 6-8 mm.

When storing finished products, they are laid on a flat, solid base using transverse wooden supports. Further laying of road slabs in the warehouse takes place using wooden spacers between all rows.

Factory manufacturing technology

The technology of forming a reinforced concrete road slab begins with the preparation of the form. At this stage, all walls of the form are lubricated with a special lubricant to facilitate the process of future stripping. After that:

• two reinforcing meshes are being installed, for the correct spatial position of which plastic limiters of the “circle” or “asterisk” type are installed on the reinforcing bars;
• a concrete mixture is placed inside the mold and compacted by vibration;
• produce heat treatment of concrete with hot steam in the heating chamber for 8-12 hours;
• the finished product is demoulded, the manufacturing quality is checked and labeled according to the type of slab.

Laying technology on public roads

Due to their versatility, reinforced concrete road slabs are used not only in large-scale road construction, but also for paving paths and driveways for vehicles in private plots of private development.

When paving roads and driveways of public importance, the preparation of the base depends on the purpose of the road in terms of the expected duration of use. Under temporary roads, driveways and platforms, it is considered sufficient to prepare a compacted sand cushion, and lay the road slabs themselves without installing a curb stone.

Concrete roads of permanent use must be laid on a multi-layer base, consisting of:

• drainage gravel layer;
• non-woven geotextile flooring;
• dense sand cushion.

At the same time, the installation of a curb enclosing stone along the edges of the road is mandatory. Every 10 meters between the stones, it is necessary to leave gaps of 5-7 cm for the normal descent of rainwater from the roadway.

The drainage layer is poured into a "trough", which is obtained by removing the top layer of soil across the entire width of the future road to a depth of 25-30 cm.

After that, the crushed stone is well compacted and covered with a layer, on which a sand cushion 10-15 cm thick is poured. The road slab is laid on compacted sand, followed by sealing the mounting grooves with loops with cement mortar or fine-grained concrete. As the extreme elements of the roadway, it is recommended to lay PB or PBB with combined side ledges adjacent to the curb stone.

To improve the quality of the road surface, the surface can either be filled with a continuous layer of concrete screed.

The use of reinforced concrete slabs in private construction

The use of road slabs in the arrangement of the backyard territory allows you to quickly and cheaply make entrances to the building, garden paths or sidewalks. At the same time, large-sized slabs 3-6 meters long with a permissible load of up to 10 tons are usually used for access roads and car passages. For example, 2P30.18-10, 2P60.1.8-10 or HDPE road slab 6000x2000x140. It is not advisable to use more powerful products in private construction.

To ensure the durability of the road, the laying of heavy road slabs should be carried out on a prepared base with a drainage gravel layer and an intermediate geotextile coating that will prevent the germination of weeds in the tile joints.

For footpaths, it is convenient and advantageous to use hexagonal, trapezoidal or small rectangular products of relatively low strength, since the load on such coatings will be small.

As a base, a compacted sand cushion is quite enough, under which a layer of geotextile is spread. This material will prevent possible germination of weeds and, at the same time, will allow rainwater to freely drain into the ground. To guarantee the preservation of the geometric dimensions of the track, it is desirable to have a concrete curb.

It is necessary to cut or prick reinforced concrete slabs to the required size along the existing reinforcement or across, at a distance of at least 250 mm from the edge. All loop grooves must be filled with fine-grained concrete, and the seams must be sealed with liquid cement mortar.

New types of reinforced concrete paving slabs

Today, manufacturers offer private developers piece reinforced concrete products for paving square, rectangular, triangular, rhombic, polygonal and other shapes. At the same time, the surface of the road slabs can be either colored or ordinary gray. The concrete surface is made smooth or embossed to reduce the likelihood of slipping on a wet surface.

Using them, you can perform a very original design of the garden plot around a residential building. It is allowed to use combinations of laying road slabs with colored gravel, paving stones, paving slabs and other materials. The basis for them should be a two-layer gravel-sand cushion.

Basic principles of proper track marking

Marking is the first stage of work on the arrangement of paved pavements for footpaths. The appearance, durability and usability of the territory largely depend on its correct implementation.

The width of the track should be such that 2 people can freely disperse on it when they meet, but not less than 0.8 meters.

The footpath running along the passage for the car must ensure the safe movement of a person while the car is moving.

Mounted hard coating must be laid at a distance of at least 1.5 meters from garden trees so that the growing roots do not subsequently damage the base. It is imperative to provide for the presence of slopes on the surface of the track to drain rain and melt water. At the same time, it is important to exclude the possibility of their arrival in the direction of a residential building and outbuildings.

Road slab size table

Eternal roads appeared in the Moscow region. There is no limit to the surprise of the villagers - instead of sinking in the mud, pulling each other out with a tow, the special equipment of large developers of cottage settlements moves along the concrete surface. In eternal roads, the resource of road slabs is optimally used, the use of which for temporary access roads is four times cheaper than asphalt.

Heavy machinery cannot harm the front surface of reinforced concrete products designed for extreme operating conditions. Upon completion of the work, the road "moves" to a new facility together with the builders, ensuring comfortable movement of excavators, dump trucks, bulldozers in the next cottage settlement. In the road slabs section, you can place an order and get more information.

Choosing a manipulator for road construction or how much does a road slab weigh?

Unfortunately, not all developers pay due attention to all the characteristics of building materials. With high-quality design, you can save the budget, not only by reducing the number of slabs needed to cover the site, but also by renting special equipment, which will take less time to create access roads.

Employees of the company know how much the road slab of each type weighs, take into account the load capacity of the boom at a certain reach. This will make it possible to get by with a manipulator instead of renting two pieces of special equipment (crane + semi-trailer), reducing costs by four times (layout before the zero cycle + dismantling when moving to another facility).

Tensioned road slab 6 x 2 technical characteristics and scope

In the manufacture of access roads, reinforced concrete products must have maximum negotiability. This condition is achieved by high performance. A 6 x 2 road slab popular with professional developers has the following types of specifications:

• water resistance of concrete - corresponds to W4
• frost resistance - within F200
• bearing capacity - permissible load per unit surface area within 1,000 kg
• product weight - 4.2 t
• water absorption - without immersion in water 5%

Multi-layer reinforcement of 14 mm thick plates allows achieving a rational combination of weight/strength. For transportation, installation, standard special equipment is used, which allows avoiding budget overruns.

• the document covers in detail the technical requirements for finished products.

Road slabs, the sizes of which can be different, are quite common today in the construction of transport branches. They are actively used in the creation of roads, autobahns, as well as highways. They are able to maintain their quality characteristics over a fairly wide temperature range, do not lose strength even at -40 0 C. Their use guarantees the reliability and long service life of the road surface.

Road slab dimensions

Depending on the brand, the plates may have different sizes and, of course, prices. So, the PD 60X12 plate has dimensions of 6000x1200x220 mm, its weight is 3.39 tons. While the plate of the PD 3-23 brand has dimensions equal to 3000x1500x220 mm, its weight is 2.42 tons. There are plates that have holes for the hatch, for example, PD 6 (s), its dimensions are 2500x1750x220 mm, and its weight is 2.3 tons. In general, plates that have holes for the hatch can have different sizes, among them 2800x2000x220 mm can be distinguished, while the weight is 2.5 tons.

State quality standards

Under mechanical influences, road slabs should not lose their qualities. Dimensions, GOST are taken into account when laying roads with a certain load. So, if the stove is produced without taking into account standards, then using it is at least inefficient, and for the most part it is unsafe.

Road slabs should be flat, based on concrete reinforced with steel elements. They are used when necessary to equip the road, whether it is temporary or permanent. These products are manufactured in accordance with GOST 21924.0-84, which involves the manufacture of a plate that is used in the construction of urban roads. In this case, the reinforcement in it is prestressed. There is another GOST 21924.2-84, which is used for the manufacture of slabs with non-stressed reinforcement. These products form the basis of permanent or temporary coatings.

Road slabs, dimensions, GOST and the purpose of which are marked on the product, may have different characteristics. So, if the product is intended for the construction of a permanent road, then in its marking you can see the designation "1P". Whereas the slabs that are intended to form temporary roads are designated as "2P". The manufacturer divides products according to performance. For example, a slab marked "2P 30-18.30" can be used to create a temporary coating, the load on which does not exceed 30 tons, but the operating temperature should not fall below -40 ° C. If there is a need to use a slab for laying a permanent or temporary road, then you can use the one that has the marking "PDP 3x1.5". The load in this case must correspond to the specific one used in the formation of the plate. To create a permanent coating, the load on which will not exceed 300 tons, and the temperature range during operation will not fall below -40 ° C, you can use a product marked "1P30-18.30". If a line is required, then the PR-3 plate should be used in operation, it is resistant to high temperatures.

Products for use in difficult conditions

Road slabs, the dimensions of which were described above, can also be used when laying roads that will be exposed to particularly aggressive external influences, for example, a temperature of -55 ° C. These qualities correspond to the plate brand "PDN", which has a fairly strong frame.

State standards for concrete

Road slabs, the dimensions of which were described in detail in the article, must be made from a material whose qualities are dictated by GOST. Thus, the product must be based on heavy concrete. It is poured into the formwork, which is pre-supplied with metal reinforcement, it (in certain brands of plates) is subjected to advance stress.

Road slabs, the weights of which were mentioned above, are made using M-350, as well as B30 M400. The technology of the work is not complicated and does not involve the use of expensive equipment. It provides for the preparation of a form, which first goes through the stage of cleaning and processing in the area of ​​\u200b\u200bthe walls with a special composition to simplify the stripping process. A pair is laid in the form and fixed in order to exclude displacement and maintain the required distance. After the master, they proceed to which, until the moment of solidification, the compaction process takes place by means of mechanical vibrators.

Heat treatment of concrete according to GOST

In order for the road slabs, the dimensions of which will clearly correspond to the shape taken during pouring, to be durable, they are subjected to heating in the next stage, which takes place in a heat chamber. The completion of the manufacturing process is accompanied by the removal of the product from the mold, quality analysis and subsequent marking. The first thing the craftsmen pay attention to is the smoothness of the surface.

Features of laying according to GOST

The quality of the road slab must comply with what is regulated by GOST. In addition to the already mentioned characteristics, it can be noted that the products are very easy to install. The main plus is that the road does not involve complex preparation. This stage provides only the need for marking and alignment. In addition, it is necessary to lay a sand cushion, the thickness of which should be in the range from 15 to 20 cm. After that, the slab is mounted, and we can assume that the road is ready.

Road, the dimensions of which can be different and are indicated above, have another advantage over traditional asphalt. It consists in the fact that the reinforced concrete product is quite easy to dismantle if necessary. At the same time, the slab will not lose its operational characteristics, and in the future the product can even be used when laying a new road in another place. This is especially true when there is a need to equip a temporary road on the territory of military camps or construction sites.

The dependence of the price of plates on their size

Road slabs (PD), the sizes of which can be different, and cost differently. For example, a plate of brand 2P 30-18-30, the size of which is 3000x1750x170 mm, has a price of 5900 rubles. But the product of the brand 2P 30-18-10 has dimensions of 3000x1200x170 mm and costs 5881 rubles. The product of the brand PD 6 has dimensions in the range of 2500x1750x220 mm, and its cost is more impressive and amounts to 11,129 rubles.

Finally

Concrete road slabs, the dimensions of which are universal, since they can be different and calculated for coatings with different loads and different external conditions, have a fairly large margin of safety. They are used in industrial construction, and they are almost never used by private consumers, although their price is acceptable. Concrete slabs, whether intended to be used temporarily or permanently, will be subjected to heavy loads, not only in terms of machinery, but also external loads during freezing and thawing, especially during spring and autumn, when temperature differences can be impressive during one day. Water that gets into the cracks freezes at night and makes the crack even bigger. That is why concrete is used in production, which must be made according to the rules.

Road slabs according to the requirements of GOST are made of high-quality reinforced concrete and have the following advantages: strength and reliability, long service life, relatively low cost, ease and high speed of installation and dismantling, resistance to dynamic and static loads.

Use of road plates

Road slabs are used in the construction of prefabricated road surfaces for vehicles (both permanent and temporary). They are considered an alternative to asphalt pavements, as asphalt pavement has certain characteristics that limit its use in some cases.

Comparing asphalt concrete with reinforced concrete, it should be noted that the first material is able to provide a much better grip of the wheels of the vehicle with the road surface. This quality is extremely important for highways with high speeds, especially in the city, as in this case traffic safety is ensured.

However, it is impossible not to mention that the binder in the manufacture of asphalt material is bitumen, which greatly reduces the strength, resistance and durability of the material, which distinguish reinforced concrete slabs. In addition, another important advantage of reinforced concrete slabs is the possibility of their repeated use for easy installation and dismantling of structures.

Precast concrete does not compete with asphalt, but is definitely more suitable for the construction of roads designed for heavy trucks.

Reinforced concrete products are one of the most demanded materials used in the construction of temporary or technological roads. The slabs make it possible to build roads for technological transport in a short time under the most difficult conditions in the case when there is neither time nor technical possibility for the construction of a full-fledged road foundation.

Road slabs are also widely used by military personnel for the construction of landfills, car parks and roads.

Production of road slabs

In the manufacture of slabs, the production technology provides for the use of sand concrete mixed with crushed stone of a certain fraction, and ordinary clean concrete. By itself, concrete has a high degree of frost resistance, so its use is especially beneficial in the manufacture of reinforced concrete coatings.

And the rigidity of the finished slab is affected by the plasticizers added to the solution, which also reduce the consumption of cement material.

Road reinforced concrete structures can be made in two ways: bench or aggregate-flow. The choice of one or another approach is influenced primarily by the amount of work.

The main principle of the aggregate-flow method is that each manipulation of the product is carried out for a certain amount of time in a certain place, which makes it possible to manufacture several types of products at once.

The stand method consists in the fact that the manufactured product is stationary, and technical devices, on the contrary, move between the stands. This approach is suitable for small scale production.
