The thesis discusses the Slovenian and Croatian technical specifications and European standards for earthworks and unbound granular layers on roads. The comparative analysis of requirements is made for road materials, quality requirements and test methods. At the beginning, the functional properties of characteristic layers in road structure are introduced. The quality criteria for materials and compacted layers are analysed and compared along with the reference test methods for quality control in Slovenia and Croatia. A comparison of requirements is made also with the reference EN standards. Analysis shows some important differences in demands and test methods.
