Title of the articleDevelopment of road-building material based on gravel-sand-cement mixture with optimal granulometric composition
Abstract.Problem statement. In many regions there are no stocks of strong crushed stone which replacement at construction of highways by the processed local materials (the gravel-sand mixture with cement, gravel-sand-cement mixture, «lean» concrete, roller-compacted concrete) – one of perspective directions of intensification and decrease in cost of road construction. Therefore, the purpose of this work was to obtain optimal compositions of road-building materials based on cement and local mineral raw materials, unsuitable or limited in use in the device of road surfaces. Results. The analysis of domestic and foreign literature on the use of processed mineral raw materials in the construction of roads, the properties of local gravel, natural sand and sand from crushed gravel, as well as the optimal compositions of processed materials and the possibility of using them in various structural layers of road surfaces. Conclusions. The significance of the results obtained for the construction industry is to justify the possibility of using unsuitable or limited in the use of local mineral raw materials in the preparation of gravel-sand-cement mixture of optimal granulometric composition. Road-building materials based on local mineral raw materials of M40, M60 and F25 strength grades have been developed.
Keywords.gravel-sand mixture of optimal composition, pavement, gravel-sand-cement mixture, roller-compacted concrete, indicators of standard compaction, physical and mechanical properties.
