The research paper provides a detailed investigation of the performance of novel Ukrainian polymer modifiers introduced into an asphalt concrete mixture in a “dry” form during mixing. The experimental study involved the modification of a hot fine-grained, dense asphalt concrete mixture of Type A with a continuous particle-size distribution, Grade I, maximum aggregate size 20 mm, in accordance with standard DSTU B V.2.7-119:2011. According to European standard EN 13108-1, this mixture corresponds to the AC16 surf mixture. The modification was carried out by adding polymer composite additives manufactured in Ukraine to the mineral aggregate skeleton. During laboratory tests, the specific effects of each additive on key physical, mechanical, and strength properties of the polymer-modified asphalt concrete were analyzed, with attention paid to its deformation resistance.
