Pavement structures, layers, and parameters must meet the strict requirements of applicable standards and regulations. The thickness of layers and the choice of materials depend on the factors involved, i.e., the traffic load and climatic factors (changes in temperature, water, rain, snow); they are also dependent on the geological environment at the road construction site and the parameters and properties of the embankment (the subgrade of the pavement). In some cases, the capacity of the existing transport infrastructure is on the edge of sustainability. The increase in the traffic load and the use of lower-class roads by freight transport, together with insufficient maintenance, has resulted in a deterioration of road conditions, thereby causing many deficiencies and failures.The required serviceability and operational performance of roads can be ensured by the choice of suitable quality materials and technological construction processes. Technologies that are environmentally acceptable and economically efficient should be preferred.
