The article evaluates the roughness of road II/584 in the cadastral area of Huty, located in a mountainous region prone to traffic accidents due to reduced skid resistance and unfavorable alignment in terms of direction and elevation. Measurements were conducted before and after surface renewal, which included the application of an AC 11 O PMB 45/80; I layer with a thickness of 50 mm. The results demonstrated significant improvements in macrotexture depth and friction coefficients, leading to enhanced road safety. This article provides a detailed methodology, results, and recommendations for similar road rehabilitation projects.
