The purpose of the work is to develop a calculation-experimental method for determining the brittleness temperature of bituminous binders, to determine the scope of application of the calculation-experimental method for determining the brittleness temperature of bituminous binders. Research methods – critical analysis of domestic and foreign literary sources on existing methods for assessing the brittleness temperature of bitumen and bituminous binders, determining the standardized properties of bituminous binders, determining penetration at temperatures of 5 °C, 15 °C, 25 °C and 35 °C and construction of temperature-penetration dependences for bitumens and bituminous binders modified with various modifiers. Finding the calculated and experimental brittleness temperature by extrapolating the obtained dependencies to the penetration level of 1.25 × 0.1 mm. and comparing its values ​​with the brittleness temperature obtained by the Fraas method are generally accepted methods of mathematical statistics for processing experimental data using the finding of linear regression coefficients, mean square deviation of values, variance, confidence interval using the Laplace function and Student's test. According to the calendar plan of scientific research work, in the last stage, the second edition of the project of the national standard was developed and sent for approval. The final version of the DSTU project was developed and clarified an explanatory note, the DSTU project file was created and submitted for acceptance to the national standardization body in accordance with the established procedure. A report on the implementation of the NDR was prepared in accordance with DSTU 3008:2015 Product Description popup.authors Ilin Yaroslav V. Bondar Tamara V. Halkin Andrii V. Pyrih Yan I.
