Road slabs - these are reinforced concrete products used for the construction of temporary and permanent roads for cars and trucks. Modern technology has a high load capacity and, accordingly, its own weight. Reinforced concrete road slabs are used when high strength of the pavement is required, fast laying of the road is required. Reinforced concrete is widely used on roads that must withstand the weight of heavy tracked and wheeled vehicles, at airfields where the requirements for them are especially high. The cost of road slabs is indicated
Production of road slabs
Road slabs are made of heavy concrete. Granite or limestone crushed stone is used as the main filler. Slabs filled with crushed granite have a longer service life. Road slabs are manufactured both with prestressed reinforcement (PDN) and reinforcement that has not been stressed. Road plates are made mainly with mounting loops. Less often, plates are made with grooves for loopless mounting or holes for collets.
The load that road slabs can withstand depends on the brand of concrete that was used in their production. Standard loads of road slabs are 10 and 30 tons. Special quality requirements are imposed on slabs used for the construction of road or railway tunnels.
Application of road plates
Reinforced concrete road slabs are used for both permanent (marking "1") and temporary roadbeds (marking "2"), for example, during the construction of a new facility, to which it is necessary to build access roads for trucks. For the construction of a permanent roadway, a PDN or PAG road slab is usually used.
When choosing road slabs, it is necessary to assess the condition of the roads and the level of load that must be sustained. When constructing temporary pavements, in order to save money, reinforced concrete road slabs that have already been in use are often used. Temporary road construction technology allows the same slabs to be reused many times, which can significantly reduce costs.
Road slab marking
Plates are marked with marks in accordance with GOST 23009. The plate mark consists of alphanumeric groups separated by a hyphen.
The first group contains the type designation of the slab and its nominal dimensions in decimeters (with values rounded to an integer), for rectangular slabs (marking "P") - length and width.
In the second group, the value of the load for which the plate is designed is given. For prestressed slabs in the second group, grades also give a class of prestressed reinforcing steel.
The brand of plates manufactured with grooves for loopless mounting or with holes for collets (instead of mounting loops) is supplemented with the letter B.
An example of a symbol (brand) of slabs for permanent roads, rectangular, 3000 mm long and 1750 mm wide (road slabs 3x1 75), designed for a car weighing 30 tons, with prestressed reinforcement made of class A-V reinforcing steel: 1P30.18-30AV.
Main types of plates
Road slab 1P - permanent coating (number 1 in the marking), granite filler
Road slab 2P - temporary coating (number 2 in the marking), limestone filler. The plates are designed for the passage of vehicles weighing 10 and 30 tons.
PAG slab - road slab 6x2, prestressed, for prefabricated airfield pavements.
By series (not all of the listed plates meet the requirements of GOST 21924.0-84, GOST 25912.0-91):
Road slab PDN - permanent coating, prestressed (for example, PDN-AV; series 3.503.1-91).
Road slabs PD - road slab (for example, PD 20.15-6; series 3.503.1-93).
Road slabs PDP - paving slab (series 3.506, slabs for airfield pavements).
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 at 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 bitumen acts as a binder in the manufacture of asphalt material, 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 popular 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.

The requirements for the versatility and quality of modern road surfaces are growing every year. The construction business does not stop developing, modern technologies do not stop surprising, and trucks are becoming more lifting and heavy. From this, the problem arose of saving the road base, which would be suitable for further exploitation. Today, the purchase of high-quality road slabs is a very topical issue.
Anler is happy to respond to the high demand for durable pavement by offering high quality concrete pavement slabs in various sizes for construction applications.
Road slabs: the price for the advantage
To reduce the time for the construction of the road and, of course, for the strength of the road surface, reinforced concrete road slabs are used. The prices of concrete products depend on their characteristics and parameters, respectively, they have a rather different purchase price. Road slabs are very often used in the military field during the construction of landfills, where the road surface must withstand the heavy weight of armored and tracked vehicles.
At present, road concrete slabs are an indispensable assistant in the construction of military and civilian runways at airports. Modern new road slabs, the dimensions and thickness of which vary depending on the name, are able to withstand a huge load of tens of tons. And, therefore, they are also well used in the area of quarrying of minerals.
Perhaps, there is the only disadvantage that PD road plates have - this is the coupling seam. Since reinforced concrete road slabs are placed directly on the ground, there is a risk that in the future they may separate and break the integrity of the road. Similar situations are seen when PDs are used in situ with moving ground layers. But this is not a significant problem if they are periodically monitored. It is possible to prevent such a situation. If the first signs appear that the reinforced concrete road slabs have begun “unauthorized” movement, it is necessary to carry out simple repair measures and then they will again take their place.
Buying road slabs means getting high-quality materials, the technology of which is very complex. Therefore, the production process is very difficult and does not allow a large amount of rejection.
Road concrete slabs: product modification
The use of road slabs (PD) in construction is due to simple assembly. This is, indeed, one of the most efficient and does not require large amounts of money, as well as one of the easiest ways to equip a reliable road.
The new concrete slabs are made from high quality materials, and their production technology is quite complex. And therefore, in the manufacture, there is a small percentage of defective plates.
Reinforced concrete road slabs exist with the designation PAG, which are operated at airfields for the arrangement of runways. The manufacturer "Detalion" is developing the slabs presented above in accordance with GOST, as well as standard concrete coatings, the mass of which is about 2 tons. You will find the dimensions for concrete PDs in the table on the website. The dimensions of the road slabs are modified depending on their width, length and height.

In recent decades, the volume of cottage construction has been expanding. Often start building with a good road that could support large loads of building materials. And the best solution in this case would be a heavy reinforced concrete road. It will withstand both heavy equipment and a large flow of goods, and will help save time and even money. It is possible to lay and mount such a road from ready-made reinforced concrete slabs in a matter of days.
Roads built from road slabs can withstand a load of no more than 30 t/sq. m. Only a road slab made in accordance with GOST 21924.0-84 can withstand such a load.
Road slab structures are divided into types:
For permanent roads - 1;
For temporary roads - 2;
According to the configuration of the plate are:
Rectangular - P;
Rectangular with a combined board - PB;
Also with 2 sides - PBB;
Trapezoidal - PT;
6-angled - PS;
Also axial diagonal - PSHD;
Also transverse - PSHP;
Half diagonal hexagonal slab - DPSh;
Also transverse - PPSh.
The plates on the upper surface have corrugations with a depth of 1.5 - 2 mm, and between the corrugations - a rough surface with a given depth of roughness.
In the marking of the designation of the road slab, its elements have the following meanings.
Plate 1P 30-18-30:
1 - permanent roads;
P - rectangular plate;
30 - length in dm (3000 mm);
18 - width 18 (1,800 mm);
