Construction of airfield strips: application and choice of road concrete

The construction of aerodromes is a complex and responsible process that requires careful attention to the lining of materials and compliance with technological stages. It is important to use coatings with increased resistance to loads, wear, damage. Most often, runways are lined with multi-layered concrete. In this case, a special type of artificial stone is used - road.



Features of the use of road concrete
This type of concrete is among the heavy ones. It is used both in the construction of ordinary highways and in the arrangement of airfield surfaces. From other materials, it is characterized by increased resistance to constant loads. The durability of concrete allows you to minimize maintenance and repair costs.

Road concrete mixtures can be used for:

• A single-layered coating or a multi-layered upper ball;
• construction of the lower layer to increase the stability of the roadway;
• Base filling with increased requirements.

In road concrete at the production stage necessarily introduced additives. They increase temperature endurance, resistance to moisture. Components are selected taking into account the climatic characteristics of the region. You can choose and buy concrete in the right amount at the Stroynerud plant, whose specialists are ready to organize prompt delivery.

Basic criteria for the selection of concrete for airfield surfaces
There are a number of indicators that affect the performance, physical characteristics of concrete. Regardless of the scope of construction, when choosing this material, you need to pay attention primarily to its brand. It defines the strength index. For airfield surfaces, compositions from M350 are used. Only for the lower words of multilayer bands, cheaper mixtures are allowed.

Other important indicators are water resistance, frost resistance and mobility. The first two parameters vary depending on the place of arrangement (temperature values, precipitation level, terrain relief). Mobility should be high enough that the solution quickly filled the formwork, evenly distributed over the surface. An alternative to concrete in the construction of airfield surfaces are plates. They are manufactured at the plant with strict observance of regulations and GOSTs. This material has a number of advantages - simplicity, high installation speed, stable geometry, resistance to various loads.
