Patents for inventions in the field of measures for preventing and combating the freeze-thaw phenomenon of roads address a topic related to the evolution of technology. Of particular importance is the stabilization of the substrate of the road transport route. An invention (J. Hornegger, N. Zanfir, M. Alupoaie, 2012) relates to a mixture used for the substrate of access roads and / or platforms. This invention relates to another invention (Y. Kadono, T. Nakazato, E. Miura, T. Kitamura, 1975) about a paved roadbed composed of a lower roadbed layer, an intermediate layer made of sulfur, an upper roadbed layer and a surface top layer. Another invention (D. Lee, K. Hong-joo, 2016) relates to a repairing and reinforcing ultrarapid hardening mortar composition, and to a method for repairing and reinforcing a road surface. Another invention (M. Radu, F. Radu, L. V. Pasăre, I. A. Buzuriu, P. Pârvu, C. G. Mudreţchi, C. Răcănel, A. Burlacu, V. Tiron, 2018) relates to a process for preparing ecological composite asphaltic mixtures to be used as road structures.

This article propose a method and means of mechanization for the protection of the generative organs of fruit plantations from radiation frost by forming insulating curtains, consisting of both heated and humidified air, which makes it possible to protect future crops through development of non-critical temperatures.
