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

Cars have long ceased to be a luxury. Now they are only a means of transportation from one point to another. Changing the technique, improving its characteristics allow you 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.

Plate for roads is used2P30-18-30. 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 dimensions of which will beshown below, are reinforced concrete elements. 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 builttemporary or permanent roads in the city, autobahns, tracks for trams and trains, 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 for the pavement, which is able to withstand the plates without being destroyed.

What are the elements

Reinforced concrete slabs for roads are massivestructure. To achieve a better grip 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 into which concrete is poured correspond to the dimensions of the finished slabs. 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.

For the production of plates, onlyhigh-quality heavy concrete. It adds reinforcing rods, entwined in a grid. All this is done to ensure that the structure during operation is resistant to high loads.

To improve resistance to frost and increasemoisture resistance, plasticizing additives are added. For the same purpose, substances that involve air into the material are introduced. 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 slabs already in use 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

Road Covering Componentsare produced with the marking of the PDP 3x1.75. The indicated marking indicates the dimensions of the finished structure (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 can be seen, road plates are made in the formrectangle. 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. Taking into account the above dimensions, it can be determined that the volume of each product is 0.893 cubic meters.

Due to high quality requirementsused raw materials and finished products road plates have a long service life. But for this, their installation must 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.
