| Title of the article | Improvement of quality of road surfacing by introduction to macadam-mastic bituminous concrete mixture of rubber crumb additives |
| Abstract. | Problem statement. The purpose of work was the research of influence of additives of rubber crumb on properties of stone mastic asphalt. Results. Comparative analysis of physicomechanical properties of the traditional stone mastic asphalt and stone mastic asphalt modified by rubber crumb from the utilized tires of «KMA» Koltek is carried out. Conclusions. The conducted research has shown that introduction of rubber crumb to stone mastic asphalt allows to raise ultimate strength indicators on compression at 20 and 50 °C, ultimate strength on stretching at split at 0 °C, couplings at shift, fatigue resistance and water resistance, to lower water saturation indicator. It is revealed that the optimum content of additive of rubber crumb as a part of stone mastic asphalt makes 1 %. Improvement of quality and increase in life cycles of road surfacing of the highway can achieve due to introduction at preparation stage to structure of crushed-stone and mastic road concrete mix of the modifying additive – rubber crumb. |
