The data presented in the article are part of disserta-tion research on the formula development and pro-duction principle of composite material for road con-struction with phosphogypsum and secondary poly-ethyleneterephthalate use. The article provides an assessment of the existing most successful and effec-tive technologies for creating asphalt concrete pave-ments with high technical performance characteris-tics, and the key role in formula is an asphalt binder on the binary system mineral powder/oil road bitu-men basement, their main advantages and disad-vantages are described. A new technological method for the asphalt concrete mixtures production is de-scribed - pelletization by rolling, which was proposed by the authors. The paper presents the study's results to determine the structured asphalt binder technical and operational properties obtained by the method of pelletization by rolling. A brief theoretical substantia-tion of the physicochemical nature of improving a number of developed composition technical and op-erational characteristics of a structured asphalt binder is presented. The dynamics of over time changes in the main structured asphalt binder indicators, from 2005 to 2019, are given. It has been theoretically proven that in a structured asphalt binder obtained by the method of pelletization by rolling, bitumen is in a film state, and the bitumen interlayers thickness be-tween the mineral powder particles is of the order of 100 nm, which makes it possible to classify the prod-uct as a nanomaterial and determines its special properties set. The data of independent and our own experimental studies are also presented, indicating the previously obtained theoretical justification correct-ness for increasing the strength indicators, improving the water saturation indicators, and the water re-sistance coefficient. The absence of negative changes in the main technical and operational properties dy-namics for 14 years confirms the possibility of storing the mixture in a cold form outside a sealed package in an unheated room, which makes it possible to assert the possibility of preparing material for future use and transporting it over unlimited distances.
