The Study of the Effectiveness of the Use of Ash and Slag in the Construction of Road Pavement During Maintenance

Abstract

There is a global problem of effective use of ash and slag waste for practical purposes. The relevance of the subject under study is conditioned by the prospects for the use of ash and slag in the design and planning of pavement structures during the road maintenance and, consequently, the need for the effectiveness of the practical use of such technologies in road construction and repair. The purpose of the presented article is to study the effectiveness of the use of ash and slag in the practical field in creating high-quality road pavement during roadway repair works. The leading method in this study is a systematic analysis, with the help of which a comprehensive assessment of the prospects of using ash and slag waste in the construction of road surfaces was carried out. In addition, the methods of generating statistical data and graphical modeling of the obtained results were applied. It was established that the road surface made with the use of ash slag had higher strength indicators compared to the surface made by traditional technologies. It was determined that an important factor in the use of ash and slag as composite additives was a significant reduction in the cost of the road surface repair process. In addition, it was determined that ash and slag mixtures could be successfully used as effective additives in the creation of new building materials. The effectiveness of the use of ash and slag waste in the construction of the road surface during repair work has been fully proven. The findings of this study are of considerable practical value for employees of road services, whose duties include solving issues of road surface repair, and for researchers involved in the practical development of alternative methods for improving the strength and quality of road pavement
