The subject of this bachelor’s thesis is the possibility of using alternative materials in base road layers. Specifically It‘s about different granular material from mines (fraction 0/22) and recyclate, the possibility of their their classification within the used base layers and assessment of their suitability for specific structural layer. The thesis subject is also assessment of suitability of laboratory tests currently used in the Czech Republic and is trying to deal with the question whether these tests are ideal or not. The theoretical part summarizes the currently used base layers, their properties, technology of their implementation and It explains the current testing system. The aim of the thesis is to define mechanical properties of the examined materials, compare them and evaluate them.
