The current topic of the reliability of bridge structures in modern conditions and the role of the structural layers of the roadway (road surface) in increasing and maintaining their operational reliability and durability are considered. The existing standard designs of road surface clothing and the materials used for their arrangement are considered. The analysis and systematization of information from Russian and foreign sources on the construction of the clothing of the driving road indicates the prospects and technical and operational advantages of using cast asphalt concrete mixtures in the upper layers of the bridge pavement. It is noted that an effective road surface made of this material is capable of resisting existing loads, taking into account the specifics of the operation of the asphalt concrete surface during the established service life, additionally performing the protective waterproofing function of the metal structures of the bridge structure. The analysis of the literature demonstrates that active scientific research on the development and creation of effective cast asphalt concrete mixtures is primarily associated with the production and modification of its bituminous part, as a medium capable of initiating "self-healing" of the composite, independently eliminating structural defects. The rich experience of various methods of modifying bituminous binders, accumulated over the past few decades, allows to predict the prospects for using cast asphalt concrete in the construction of the roadway of bridge structures, based on improved binders, in order to create new high-quality materials that can improve the quality of the bridge network in the country.
