Under the influence of environmental factors, such as: snow, rain, increase or decrease in temperature, the influence of high loads of various transports, a gradual wear of the road surface occurs.
Due to the constant climatic influence and hydrogeological impact in the designs of airfields, irreversible consequences and changes occur, which leads to errors in the state of coatings. Also, damage to aerodrome coatings can occur due to non-compliance with the operational rules, established standards and not comply with fully design decisions.
In order to subsequently avoid premature damage and increase the durability of use, we should strictly adhere to the requirements for operation, create a competent and regular system for monitoring the state of the surface of the coatings at all stages of operation. Must be established the procedure for the planned current and overhaul.
In the process of daily operation and under the influence of regular loads from air and vehicles, deformations appear to the PAG, leading to the possibility of emergency situations.
Such deformations include: peeling of the upper layer of the surface of the plates, the appearance of cracks, springs, destruction of connecting joints and raw materials that fill the seams, warping and displacement of the plates themselves may appear on the corners and edges of the plates.
The listed deformations lead to:
reduce the thickness of the plate, which is reflected in the ability to withstand the loads;
the formation of potholes, shells that increase the accident rate and reduce operation safety;
an increase in the width of the connecting seams and irregularities, which will negatively affect the dynamic loads;
the intensity of the formation of ice;
reducing the bearing capacity of plates and creating favorable conditions for the penetration of water into the ground;
drawing of concrete coatings, as well as to their skew.
Therefore, for safe, durable, and most importantly, safe operation, the adequacy of the working project when laying out the roadbed, prevention of premature deformations, competent operation, which meets established standards, rules and adopted standards, plays a very important role. Do not save on current and overhaul, because not only the lives of many people can depend on this, but also your own.
