Abstract
The article presents recent studies of high rap half-warm mix asphalt, which indicates the promising application of semi-warm mixtures with a high content of asphalt concrete crumbs and makes it possible to create durable and resource-efficient materials. The use of asphalt concrete crumbs not only saves materials and solves the issue of its disposal, but also allows saving energy resources and reducing harmful emissions into the environment due to lower technological temperatures for the preparation and installation of semi-warm mixtures. At the same time, this technology has not yet been sufficiently researched, especially in domestic practice, and requires laboratory and field experimental studies with subsequent optimization of formulation and technological parameters, as well as the development of mathematical models of the dependence of the physical and mechanical characteristics of semi-warm mixtures on the components of the material and technological parameters. Research in laboratory and field conditions on the long-term quality characteristics (calculated characteristics, resistance to rutting and atmospheric influences) of mixtures with a high content of asphalt concrete crumbs is also relevant
