| Title of the article | Requirements for sealing expansion joints of cement concrete pavements of highways |
| Abstract. | Problem statement. High-quality and timely sealing of expansion joints of cement concrete pavements is an integral part in maintaining a high service life of highways. In connection with the extension of the types and quality of sealing materials, it is necessary to develop requirements for sealing expansion joints. The purpose of the work is to determine the factors on which the choice of sealing materials depends, which in turn affects the performance of expansion joints of cement concrete pavements. The objectives of the study are: analysis of the main sealing materials for expansion joints of cement concrete pavements, comparison of their main characteristics, as well as identification of factors that influence the service life of expansion joints of cement concrete pavements. Results. The main climatic and operational influences on expansion joints that affect the service life of cement concrete pavements are described. The main types and causes of destruction of sealing materials in expansion joints are considered. Recommendations are given regarding the correct purpose of sealing materials, taking into account the natural and climatic conditions of operation of cement concrete pavements. Conclusions. The results of the study make it possible to establish the advantages and disadvantages of various types of sealing materials and provide recommendations for their selection. |
