Road plates 2P30-18-30: dimensions and characteristics

Cars have long ceased to be a luxury. At present, they are only a means of transportation from one point to another. Changing the technique, improving its characteristics make it possible to expect a comfortable trip. And no matter how long it lasts. But the comfort of movement depends not only on the vehicle. Great importance in this matter is the quality of the road surface. And serious demands are made on him.

To cover roads, a road slab 2P30-18-30 is used. Dimensions, weight and other indicators of it are taken from the standard (GOST21924.0-84). The quality of materials used for its production is also subject to strict standards requirements.

Application area

Road plates 2P30-18-30, the sizes of which will be indicated below, are elements of reinforced concrete. They are used in the construction of roads with different traffic. Due to the use of reinforced concrete slabs withstand significant loads.

With the use of these plates can be built temporary or permanent roads in the city, autobahns, tramway and train routes, highways. The load from vehicles to the road surface must not exceed the values of the coefficients H-10 and H-30. This means that when moving columns of vehicles with a weight of 10 or 30 thousand pounds, the parameters of the road plates will not change. In other words, this is the permissible maximum load limit on the pavement, which is able to withstand the plates, without undergoing destruction.

What are the elements

Reinforced concrete slabs for roads are massive structures. To achieve better adhesion of the wheels to the road surface, the plates on one side are covered with corrugations. These grooves are formed at the stage when road plates 2P30-18-30 are poured. The dimensions of the molds in which concrete is poured correspond to the dimensions of the finished plates. At the bottom they have corrugations in the form of a diamond, the depth of which reaches 1.2 millimeters. Concrete is compacted. Further, its surface is treated with nylon brushes. As a result of this treatment, roughness is formed on the surface of the plates.

By standards, the influx can cover road plates 2P30-18-30. Their dimensions should not exceed fifteen millimeters.

Only high-quality heavy concrete is used for the production of slabs. It adds reinforcing rods, entangled in the grid. All this is done to ensure that the structure during operation is resistant to high loads.

To improve resistance to frost and increase moisture resistance, plasticizing additives are added. For the same purpose, substances are introduced that involve air into the material. Thanks to these additives, the elements are not damaged in the cold season due to low temperatures, do not collapse under the influence of atmospheric precipitation, and can withstand the high weight of passing vehicles. Their characteristics are so high that even used plates are suitable for use.

Characteristics of elements of this type allow using them in areas with different climates. Their application will be possible in a wide range of ambient temperatures.

Road plates 2P30-18-30: dimensions

Constructive elements of the road covering are produced with the marking of the PDP 3x1.75. The indicated marking indicates the dimensions of the finished structure (the length of the product and its width). The thickness of the plates is not taken into account. Its decoding is defined as follows:

• The thickness of the plate is 170 millimeters.

• The length of the product is 3 thousand millimeters.

• The width of the construction is 1750 millimeters.

As you can see, road plates are made in the form of a rectangle. Their surface is corrugated, with grooves to create a good grip of the wheels of vehicles with the surface of the road surface. Each plate weighs 2.2 thousand kilograms. Given the above dimensions, you can determine that the volume of each product is 0.893 cubic meters.

Due to high requirements to the quality of raw materials and finished products, road plates have a long service life. But for this, their installation should be carried out in accordance with the requirements of the manufacturer and the established regulatory documents. If all the necessary requirements are met during the construction process, the road surface will be of high quality and durable. And this is the key to a pleasant and comfortable movement.
