Forest roads, such as special-purpose roads, are designed under substantially limited conditions (financial, time) and with significantly different requirements in comparison with common road pavements. The design parameters (class of traffic volume/heavy vehicles, level of damage, life span, transport mode) are different, and the survey and design/project process are limited. In addition, forest roads are evaluated from the environmental viewpoint in terms of maintaining environmental quality. Optimization of the road pavement design and implementation process is based on the selection of economical road arrangement, materials, and the use of mechanisms and work procedures with the aim to make as slight an impact as possible on the forest ecosystem. The selection of an alternative parameter for the evaluation of the bearing capacity of subgrade and base courses and the selection of suitable materials is based on the evaluation of laboratory and in situ tests and their correlation relationships in connection to road pavement materials (soil, layers). The evaluation of a large set of simultaneous measurements by a static loading test and a light dynamic plate, and the determination of their correlation allowed us to use the deformation modulus of the test by the light dynamic plate Edyn, Evd, Mv, and as the main parameter for the evaluation of forest road pavement layers. When constructing forest road pavements, environmentally, socially, and economically suitable procedures for the survey, design, construction, and construction monitoring can be used.
