Plates road (PD). Road slabs: dimensions, GOST Products for operation in difficult conditions

Reinforced concrete road slabs are made from heavy grade concrete with strong stressed or non-stressed reinforcement, which makes it possible to withstand significant mechanical loads without deformation. For improved adhesion of car tires to the road, reinforced concrete road slabs have a continuous notch on the front side. The road slab is used at construction sites, logging, in mining areas where a hard road surface is required for the movement of special equipment.

Pavement markings:

• The letters in the product name indicate the shape: P - rectangular slab, PT - trapezoidal, PSH - hexagonal, PDN - road stressed slab (used for road construction in difficult conditions).
• The digital marking of rectangular road slabs consists of 3 numbers: the first number indicates the length, the second - the width, the third - the maximum load in tons.

KZHBI No. 2 sells road slabs at manufacturer's prices. Dimensions, characteristics, weight and series of products that you can order in the assortment of the plant are presented in the table.

Concrete road slab: buy from the manufacturer

The road slab allows you to significantly reduce the cost of building permanent roads and laying temporary ones.

By appointment, concrete road slabs can be distinguished:

• 1P - for urban roads with light traffic;
• 2P - for temporary roads;
• PD and PDN - for roads with heavy and oversized vehicles;
• PD6, PD10 - with a hole for installing a well.

Concrete concrete plant No. 2 offers road slabs made in accordance with GOST 21924.0-84. We use high quality materials: heavy concrete М350-400, class A I-III, Вр-I reinforcement. During the manufacturing process, two reinforcing meshes are fixed in the mold at a distance and poured with concrete. The mass is compacted by vibrocompression, which makes it possible to achieve the absence of pores in concrete road slabs. Then the form is fed into the heat chamber for heating. The last stage of production is quality control and labeling of products.

Main technical characteristics of concrete road slabs:

• value of concrete compressive strength from B22.5;
• frost resistance exceeds 100 freeze-thaw cycles;
• the water absorption coefficient is less than 5.7%;
• road slabs are designed for loads H-30 and H-10.

One of the main advantages of the products is the simplicity and high speed of installation. A sand cushion (thickness 15-20 cm) is applied to a pre-leveled surface and compacted using a vibrating plate. Concrete road slabs are laid on the prepared base. Then the mounting loops are welded on the sides, and the gaps between the plates are filled with concrete mortar. Asphalt pavement will significantly extend the life of the road and protect the cement road slabs from external destructive influences.

PD (road plates)

Road slabs are widely used in the construction of highways, highways, construction and industrial sites, access roads, warehouse and industrial buildings and structures.

Road slabs are the ideal material

Road construction using concrete slabs provides significant advantages:
simplification of the roadway construction process;
reduction of construction time;
increasing the reliability and wear resistance of the coating, increasing its service life;
reduction of construction and operating costs.
Due to the high level of demand for products, domestic enterprises have launched the production of various modifications of reinforced concrete slabs for the construction of road surfaces.

Road slabs PD, PDP, PDS - the necessary variety

In road construction, a fairly wide range of tasks is solved. In accordance with this, reinforced concrete road slabs of various designs are used for various conditions. The most common options include:
Plate road PD. One of the most versatile types of products, designed primarily for the installation of prefabricated pavements of temporary roads in cities and towns. Due to the high strength of concrete and powerful reinforcement of the slab, road PDs can be used in the construction of access roads for industrial enterprises and industrial zones. Available in several sizes and designs. For example, road slabs PD10 and PD6 are designed to organize wells in the roadway and have a hole for installing hatches.
Plate road PDP. It is in great demand and is intended for the organization of permanent and temporary coatings of roads, motorways and city highways. Convenient dimensions, lightness and low cost, together with excellent strength and resistance to climatic influences, contribute to the spread of PDP boards throughout the country.
Plate road PDS. The main purpose is the construction of temporary roads for industrial enterprises. The strong reinforcement and high density are excellent for paving roads with heavy heavy traffic.

For the construction of roads, other types of reinforced concrete slabs are also used, with stressed and non-stressed reinforcement, various surfaces, connection methods, etc. The company "Dorplit ZhBI" offers a wide range of new and used road slabs. Details are in the price lists and on the official website.

Reinforced concrete road slabs are designed for temporary or permanent pavement. They are rectangular flat reinforced concrete slabs 14-18 cm thick. Basically, they differ in size and load capacity. The load, in turn, depends on the brand of concreteused in the manufacture of reinforced concrete slabs. The higher the grade of concrete, the greater the load the future roadbed can withstand. For example, if we are talking about road slabs PDP 30-18-30 (3x1.75 m) and their analogues, then there are two options: 10 load and 30. Index n10 or n30. The numbers after the index "n" indicate the permissible load in tons.

We offer you to get acquainted with the average market prices for road slabs. Similar prices are relevant for many concrete goods manufacturers at the moment (excluding delivery).

Road slabs PDP and PAG

PDP 30-18-30 is of course the most common and popular type. However, despite their popularity, PD road slabs have certain limitations in terms of operational loads. With regular passage of heavy vehicles on them, they are subject to gradual destruction. Especially under the condition of poor-quality laying (bad pillow, insufficiently compacted soil, sand or gravel, etc.).

If heavy truck traffic is planned, you should take care of a more reliable and durable road surface. In such cases, it is recommended to build roads from PAG slabs. These are the so-called airfield plates.

There are two main types of PAG differing in thickness: 14 and 18 cm (there is PAG-20), as well as in size 6x2 and 3x2 meters (popularly they are called "half-pags" :-)) The initial purpose of PAG is the construction of airfield pavements . Therefore, you should not doubt their reliability and durability. Reinforced reinforcement frame and high-quality concrete m350 have a positive effect on the final quality of the product. PAG airfield slabs have a corrugated surface, which also contributes to the operational and aesthetic characteristics. In modern Russia, quite a lot of different areas, polygons, etc. have been preserved, lined with airfield PAGs back in Soviet times, but retaining their main function to this day.

If funds and budgets allow, and you are looking not to tomorrow, but to the day after tomorrow, then the PAG road slab is the most reliable solution when constructing reinforced concrete roads. Pay today and forget your road problems for years to come.

In recent years, road slabs are more and more often used only for organizing temporary access roads. For example: an object starts to be built. There are no access roads. It is necessary to organize the entrance of trucks for the transport of building materials. The bulldozer leveled the soil, poured out a sand cushion, and slabs were laid on the compacted sand base. In general, the road is ready. Firstly, this kind of work is carried out quite quickly, and secondly, the use of ready-made precast concrete at a construction site is effective. You can immediately drive along such a road, unlike a monolithic coating cast from ready-mixed concrete.

Another important positive moment from the use of road slabs is the possibility of their further re-laying, transportation to another object, etc. Thus, we get the opportunity to save on the construction of temporary access roads. Precast concrete is one of the few ways to quickly build a reliable pavement that can be reconfigured later.

Laying or laying road slabs

I would like to mention the main stages and rules for the construction of access roads from prefabricated concrete products. It would seem, stele and stele. But everything is not as simple as we would like. Neglect of elementary building codes and technologies almost always results in additional costs for rework and the purchase of new materials. Therefore, I would like to save your nerves and wallet from possible disappointments from the construction process. So, let's be clear - how to properly lay road slabs. Here are the main steps that you need to follow in the process of building your road.

• The top layer of soil is cut off. Any bumps, potholes, etc.
• Sand is brought in. Better career, it is less creeping and dusty than river. Accordingly, it is better compacted (rammed).
• The sand is leveled over the entire width of the future road (slightly wider than the width of the roadway) with a layer of about 15-20 cm. Although more is better. But it all depends on budgets.
• Sand must be shed with water and rammed with a vibrating plate (preferably two or three times in layers of 7-10 cm). In general, a vibratory roller would be more convenient, but it would be a little expensive: rent, bring on a trawl, roll, take. In this situation, you can get by with a vibrating plate weighing 100-150 kg. The cushion is rammed and leveled at the same time.

  All work on backfilling and ramming should be controlled with a level or ordinary rope beacons stretched along the level. After tamping, the surface of the cushion must be absolutely flat, without holes and slopes. In the future, there is nothing more to level them. The reinforced concrete pavement of the future road will already lie on this pillow.

• Road slabs are laid on a leveled and compacted sand cushion.
• Trailer loops on the sides are welded together by electric welding. This is so that during operation - the plates do not spread and do not disperse. The voids are filled with concrete or cement mortar. This, of course, is not a mandatory event, but after pouring, you get an absolutely smooth driveway, without holes and unsightly pieces of iron at the joints.
• Here is the road ready. Of course, it doesn’t look like an autobahn, but if you “shake your wallet”, and put asphalt on top, it will be beautiful in general. Reliable, practical and durable. Asphalt pavement will protect reinforced concrete from the damaging effects of moisture and frost.

In no case do not lay road slabs on bare ground without a carefully compacted sand cushion. If you do not make a subbase of sand, then such a road will not last long: one or two seasons. And then: either shoot and lay again on the pillow, or watch how your money continues to dissolve in clay ...

Cars, trucks, trams, trains, airplanes, construction vehicles - these are all vehicles with a considerable mass, under the pressure of which the roadway quickly becomes unusable without a reliable foundation.

The strength and durability of the roadway directly depends on the quality of its base - the road slab. Our products manufactured in accordance with all requirements (road slab, etc.) retain their properties even under extreme temperature changes (from -40 ° C) and withstand the load of even large-tonnage vehicles.

Road slabs are presented in three varieties (here you will find all types of road slabs):

airfield road slabs,

road slabs for urban roads,

road slabs for tram tracks.
