| Title of the article | The influence of temperature control of asphalt concrete mixture and mechanical loads on the strength of asphalt concrete |
| Abstract. | Problem statement. One of the main objectives when creating an asphalt concrete road surface will always be its durability. For this purpose, it is proposed to use the process of preliminary thermostating of the asphalt concrete mixture. The purpose of the work is to study the positive effect of this process on stabilizing the strength of asphalt concrete and reducing the negative impact of mechanical destruction on it under the influence of load. The objectives of the study are to determine the activation energy of the destruction of bitumen and its adhesive bonds, as well as to determine the coefficients of their sensitivity to mechanical stresses. Results. A method for determining the durability criteria of asphalt concrete composites based on the thermofluctuation theory of strength by S.N. Zhurkov is described. Some ways to improve them have been proposed, including by modifying bitumen. Conclusions. The significance of the results obtained for the road construction industry is that through the use of temperature control it is possible to obtain a more durable asphalt concrete pavement. |
