One of the important reasons for reducing the service life of asphalt concrete surfaces (ruts, plastic deformations, potholes, cracks, etc.) is the low quality of used road oil bitumen. This determined the relevance of the development of bituminous binders with increased physical and mechanical properties. This is especially true for organic binders that are used in the production of Stone Mastic Asphalt (SMA). The paper presents the results of a study of BND 70/100 bitumen modified by the introduction of polymers (atactic polypropylene APP and styrene-butadiene thermoplastic SBS L 30-01A), using a single-stage technology for preparing a polymer-bituminous binder. The influence of binder modification on the physical, mechanical and operational properties of road asphalt concrete is shown on the example of Stone Mastic Asphalt (SMA-20) relative to the basic samples made to control the dynamics of changes in the properties of composites. A comprehensive assessment of the effectiveness of modifying the composite based on various binders was performed on the basis of generalized quality criteria obtained by determining the partial quality criteria of the composite, taking into account the weighting coefficients. The comparison and analysis of the obtained performance criteria is made. The comprehensive assessment of the performance indicators of binders and composites based on them demonstrates that obtaining an objective conclusion about the quality of bituminous binders is not correct without investigating their influence on the properties of the final product, in the case of SMA.
