At an installation of the hot mix asphalt on a construction site, it is necessary to achieve the designed quality of the built asphalt layer. On the quality of the built asphalt layer affect the temperature of the asphalt mix, the quality of a bearing layer, external weather conditions and energy invested during the installation of hot mix asphalt. Laboratory tests aimed to determine the dependence of the invested variable compaction energy on asphalt mix AC 8 surf 50/70 AG1 M4 and the achieved density of the test specimens in the laboratory conditions. The designed asphalt mix was made up in the laboratory of stone fractions of igneous origin, stone dust of dolomite origin and bitumen 50/70. The obtained results indicate that the invested compaction energy significantly affects on the achieved quality of the laboratory made asphalt specimens.
