Abstract: Climate pavement adaptability is an integral part of a holistic concept of road design, construction, and pavement management. One of the possibilities for fulfilling the mentioned author’s premise in sustainable cycle pavements in the cold region of Central Europe is using composite foam concrete (CFC). To establish the credibility of the design of these pavements, we objectified the correlation dependencies of average annual air temperatures and frost indexes, for altitude regions from 314 to 858 m in the period 1971 to 2020, at its height above sea level. As part of the research on the increase in tensile strength during bending of CFC, extensive laboratory measurements were carried out and validated by isomorphic models of real roads, which enabled an increase in tensile strength during bending from 0.376 to 1.370 N·mm −2 for basalt reinforcing mesh. The research results, verified through FEM (Finite Element Method) models of cycle pavements, demonstrated a possible reduction of total pavement thickness from 56 to 38 cm for rigid pavements and 48 to 38 cm for flexible pavements.
