Pollution of the roadside environment by dust particles from road surface repairs.

The purpose of the study is to investigate the practical aspects of environmental pollution near motorways by dust particles formed during repair works and to identify specific ways to improve the overall environmental situation near highways and reduce the level of pollution during road maintenance. The leading approach is a systematic analysis of the problems of environmental pollution by dust emissions in general. The study results reflect the entire volume of research efforts made to determine the optimal composition of the concrete mixture for road repairs, which allows reducing the emission of dust particles into the surrounding roadside environment and improves the environmental situation on the roadside.

Comparative analysis of the influence of various materials on the state of the roadside environment during the road repair.

The relevance of the study is conditioned by the urgent need for the practical derivation of clear criteria for assessing the degree of influence of certain materials used in road construction on the state of the roadside environment directly during such works, including the overall environmental situation in the area. In this context, the main purpose of this study is to conduct an experimental investigation to determine the physical and mechanical properties and durability of some building materials used during road repair, to perform a comparative analysis of the results obtained to determine their optimal use in terms of influencing the state of the roadside environment during the repair of a highway section. The leading method in this study is a combination of a systematic analysis of the influence of various materials on the state of the roadside environment during the repair with experimental studies. The results obtained indicate the different influence of materials used in road repair works on the state of the roadside environment and the need to choose their optimal combination in the future when repairing the roadway. The results obtained and the practical conclusions formed on their basis will be of significant importance directly for the employees of the road repair services, who, by their occupation, solve the issues of using specific building materials when repairing and eliminating damage to the roadway, as well as for researchers who solve theoretical problems of choosing specific materials for carrying out repair works, from the standpoint of assessing their impact on the roadside environment.
