Interaction of the receiving hopper of the loader with the medium: ways to minimize temperature segregation
Abstract
In recent years, the transport infrastructure and road networks in our country have been rapidly developing: existing city roads, modern chords and high-speed highways are being reconstructed and new ones are being built. In the process of building roads from asphalt concrete mixture, material handlers are increasingly used. This article considers the change in the temperature of the asphalt concrete mixture when interacting with the receiving hopper of the material handler. The theoretical aspects of increasing the temperature when using a material handler are considered, and a full-scale model is proposed to confirm the theoretical aspects of increasing the temperature of the asphalt concrete mixture when interacting with the material handler during the laying of asphalt concrete pavements. Experimental studies were carried out, for which a test program and methodology were prepared, a full-scale model of the receiving hopper and a road section were made to obtain reliable results. Based on the results of the study, the authors proposed recommendations for transferring asphalt concrete mixture from the body of a dump truck to the receiving hopper of an asphalt paver. Compliance with the technology of reloading asphalt concrete mixture with a reloader is the most important factor contributing to maintaining the temperature regime and quality of paving.
