Abstract

ntroduction. DSTU EN 13108-1 establishes requirements for asphalt mixtures used for the arrangement of pavement layers of roads, airfields, etc. These asphalt mixtures are used for arranging the base layer, binding layer, and a surface layer. Problem statement. A special feature of DSTU EN 13108-1 is that it establishes general requirements for all indicators, in particular for grading. That is there are no specific requirements for the grading of asphalt mixtures depending on the road category, traffic loading and the location of the asphalt concrete layer in the road pavement structure. Therefore, it is advisable to consider in detail the requirements for the grading of asphalt mixtures, compare them with the requirements of national standards and propose appropriate national requirements. Purpose. Establishment of national requirements for the grading of asphalt mixtures according to DSTU EN 13108-1. Materials and methods.
