Abstract
High-quality surface treatment of highways requires state-of-the-art technology ensuring the rational technological process. It is the first time that a Bitumen and Aggregate Spreader (BAS) is considered in this article as a set of inter-related controlled systems serving one final purpose – building rough and protective wearing layers on road surfaces. Such approach allowed considering bitumen and aggregate spreader and its peculiar input and outputting characteristics as one unit that can be managed according to the principles of automatic control, which permits extending its functional capabilities. One of the main BAS assemblies with synchronous component spread is presented herewith, i.e. aggregate preparation and spread unit. This paper discloses the main stages of BAS parameter calculation, as well as the discovered and experimentally confirmed correlation ratios for further calculations of its main parameters serving as the input data for BAS automatic control system functioning algorithm are found and experimentally confirmed.
