Construction and operation of airfields is the special professional niche demanding use of special materials for sealing of seams of airfield coverings. To ensure safety at operation of airfields the slightest crack has to be eliminated instantly, restoring integrity of a cloth. However the majority of the materials used for sealing of seams and cracks are not capable to eliminate qualitatively at the same time all defects on the problem site. It is especially difficult to process a deformation seam which small cracks are badly filled with viscous sealants of a dense consistence.

The product range under the is SHAVEN trademark includes mastics which are classified as the sealants of small viscosity capable to get into the thinnest deformation seams, having provided, thus, reliable sealing of the damaged site. Besides, it is expedient to use mastic, an emulsion, the cord for seams of the company "Is shaven" already at a stage of construction of airfields.

The technology of the device and sealing of deformation seams of airfield coverings for the last 20 years is in many respects fulfilled and generally does not represent essential difficulties. Constructive decisions (the design decision) for all types of deformation seams are universal, and technological process is provided with all complex of the modern equipment. Geometrical parameters of deformation seams, depth and width, pay off proceeding from extreme sizes of horizontal and vertical movements of edges of seams, thickness of a covering and type of transport loading.

Standard procedures of sealing of deformation seams of monolithic cement - concrete coverings include the following operations: cutting by the diamond tool; purge hot compressed air; processing of walls of seams polymeric primer; filling by the bituminous and polymeric sealant warmed up to the temperature of 170 - 180 OS and finishing processing of a surface by fine mineral material. In more detail the technology of sealing is described. On sealing of defshv. The bituminous and polymeric sealants of various brands used for these purposes, differ according to the physicomechanical characteristics. At the choice of brand of sealant for airfield coverings it is necessary to consider weather climatic conditions of the area of alleged operation, first of all. Card of climatic zones of use of mastic. For ensuring high level of long - term reliability of deformation seams, the applied sealant has to correspond to real service conditions. The warranty period of service of sealants of the BP - G brands, at respect for technology of their application, has to make not less than 2 years.

Essential growth of air transportation and automobile traffic for the last decade, increase in lump of aircrafts and vehicles, resulted in need of creation of the pressurizing materials of new generation having a unique complex of operational properties. Use of modern production technologies, high - quality polymeric materials, complex softeners and stabilizers, allow to produce such pressurizing materials as "NORD" and "Arktik - 3" providing more than 5 summer term of faultless operation. NORD and Arktik - 3 sealants are the premium class products intended for the device of deformation seams on important sectors of artificial coverings of airfields, such as runways, the main rulezhny paths and platforms.

For cement - concrete coverings, as a preventive measure. Premium class sealants for airfield coverings - "To NORD" and" Arktik - 3" are directed against a chaotic treshchinoobrazovaniye, are appointed for the device of the deformation seams capable to compensate deformations of coverings and designs. The deformation seam has four main types: seams of compression, expansion, technological and seams of an adjunction to other types of coverings and to designs.
