The design and service life of structures depend on various factors, including material properties, calculation model accuracy, and the methodology used. In Low Volume Road pavement design, it is essential to consider subsoil behavior and factors influencing its mechanical properties, particularly moisture, which significantly affects soil deformation when improved or no improved materials. This issue becomes more relevant under climate change conditions. The resilient modulus, derived from the cyclic California Bearing Ratio test, is a key parameter for assessing soil resistance to repeated loads. Furthermore, road design should consider the recreational potential of the area and ensure proper maintenance for sustainable use. Intensive use can accelerate road degradation, leading to environmental damage and reduced recreational enjoyment. Therefore, solutions based on best practices and experiences from the Czech Republic and other countries are being explored. Finally, poorly maintained, damaged, or excessively deformed road surfaces not only reduce functionality but also increase fuel consumption and the costs associated with non-renewable resources. Ensuring proper design and maintenance can help mitigate these negative impacts while promoting sustainable infrastructure. The paper will present the results of tests investigating the effect of moisture on both the Resilent Modulus and permanent and elastic deformation of the subgrade.

Keywords: resilient modulus, cyclic test, soil geotechnic analysis, environment for recreation
