Abstract: The purpose of the research of this master’s qualification work is to design and test a mixture of cold bituminous road for year-round pothole repair (SBMD (R)) with Teramin PA-4. The object of research in the work was: physical and mechanical indicators of a mixture of cold bituminous road for year-round repair to eliminate potholes (SBMD (Р)) with a special additive called Teramin PA-4. The subject of the research in the paper was: Mixture of cold bituminous road for year-round repair to eliminate surface potholes (SBMD (R)) with a special additive called Teramin PA-4. The tasks of the work study were: 1. To conduct a review of literary sources of the problems of researching cold road mixes for pothole repair. 2. Select research methods for (SBMD (R)) 3. Select the necessary materials for design (SBMD (R)) 4. To design and test options (SBMD (R)) for autumn and winter periods. A review of literary sources of the problems of researching cold road mixtures for pothole repair was carried out. Selected research methods for (SBMD (R)). Selection of the necessary materials for design (SBMD (R)) was carried out. Variants (SBMD (R)) for summer and winter periods have been designed and tested.
