Abstract
Statement n of the problem. Establish the effect of the size of material fractions, thickness and percentage of bitumen emulsion obtained by milling non-rigid pavements on the deformation of the layer during pavement construction.Results. It has been experimentally proven that there is a correlation between the density, strength and deformation of the layer under the action of a sealing load. The material obtained by cold milling of old non-rigid coatings has its own characteristics that must be taken into account when using it. The introduction of a binder into asphalt granulate affects not only the properties of the asphalt-granular concrete mixture, but also the formation of the structure of the pavement layer. Conclusion. Dependencies for calculating the deformation of the pavement layer have been obtained, which make it possible to predict the strength characteristics of the layer by deformation at different sizes of material fractions, layer thickness and percentage of bitumen emulsion in the mixture under the existing load during the compaction process.
