| Title of the article | Analysis of application experience of warm asphalt mixes |
| Abstract. | Problem statement. The road construction season in the climatic conditions of the Republic of Tatarstan is limited in time, therefore, the main laying of asphalt mixes is carried out from April to October. The range of carriage of such mixtures, taking into account the territory of the republic and the limited number of asphalt mixing plants, is often 100 or more kilometers. With the increasing cost of energy resources, the aim of the study is to identify a decrease in energy costs for the production of asphalt mixes. Results. The main results of the study lead road workers to the use of warm asphalt mixes, which can solve these problems by reducing the temperature of preparation and laying of asphalt mixes. A separate niche in the field of modification of asphalt mixes is occupied by natural waxes and synthetic paraffins. They are used for the production of warm asphalt mixes, as well as to give cast asphalt mixes better workability. Conclusions. The significance of the results for the construction industry lies in the fact that the use of a warm mixture made by the presented technology and concentrate by the Canadian company «CantatAssociatesInc» allows you to extend the season for laying asphalt mixture, up to freezing temperatures. The range of the wagon and the residence time of the mixture in the car body is much longer. The mixture does not cool down for a long time, remains plastic, homogeneous. In addition, the mixture is odorless, which is essential for laboratory tests. |
