Currently, much attention is paid to the improvement of production technology airfield pavements. This is due to the fact that the airfield pavements are exposed to the combined effect of diverse factors, such as temperature extremes, shock, and others. In recent years, production technology, new materials are widely used airfield pavements, which are produced on an industrial scale. Using them as airfield pavements can increase the battery life and improve the safety of air operations. In this study, the main problems arising from the operation of cement-concrete airfield pavements. To ensure the quality of long-term performance characteristics of the coating is necessary to pay great attention to the quality of the sealing seams airport paving material. Appeared in recent years, the work on the application of physical fields in production technology of polymeric materials have shown that the use can increase the number of indicators derived composites. In order to improve the quality of sealants can be applied magnetic fields of varying intensity. The above set of experimental studies on the treatment of sealing materials in a constant magnetic field with varying intensity has shown that this development can improve a number of performance characteristics of the sealant. Described analysis airfield sealant to frost. As a result of experiments, optimized conditions for the magnetic treatment of the sealant. Application of magnetic treatment with tensions from 6·104 to 30·104 A/m for 15 minutes helps to increase frost resistance sealants. The results confirmed the theory of polymer orientation under the action of magnetic treatment.
