Bituminous mixtures are of great importance in today's construction, especially in civil engineering, where they are mostly used for asphalting roads, so such mixtures are also called asphalts. In addition to being used in road construction, they are also in demand as waterproofing for various elements in construction. Bitumen, which is the main component of mixtures, with its quality properties such as impermeability and good adhesion, gives the mixtures high quality and an advantage over other materials. For the preparation of bituminous mixtures, in addition to bitumen, an aggregate, stone flour, also called filler, and, if necessary, additives are needed to improve the quality of the mixture. In bituminous mixtures, natural aggregate is most often used, which must be solid and durable. In order to check and confirm the quality of the aggregate, Los Angeles tests, determination of granulometric composition, resistance to polishing and wear, and surface abrasion are carried out. Mixtures are produced in asphalt bases where the necessary ingredients are dosed depending on the load that the future road must take. Everything takes place under high temperatures; the mixture is transported hot and installed as such. Such a sample is taken to perform various tests in the asphalt base laboratory to determine the quality of the prepared mixture, the proportion of cavities, the density of the mixture, and the proportion of bitumen in the mixture. The mixture itself is installed with a machine called a finisher, and later compacted with rollers. Finally, the flatness of the route is checked and tests are performed on a sample drilled after setting and drying of the mixture.
