In addition, from a Czech viewpoint, there was clearly the necessity to determine the quality of asphalt mixtures prepared with selected fillers provided by different neighborhood quarries and companies. This paper discusses an experimental investigation and a machine understanding modeling performed by a decision tree CatBoost approach, centered on experimentally determined volumetric and technical properties of fine-grained asphalt concretes ready with selected quarry fillers made use of as an option to old-fashioned limestone and Portland cement. Air voids content and tightness modulus at 15 °C had been predicted on such basis as seven input factors, including bulk thickness, a categorical adjustable identifying the aggregates' quarry of beginning, and five main filler-oxide items determined by ways X-ray fluorescence spectrometry. All mixtures were made by fixing the filler content at 10% by size, with a bitumen content of 6% (PG 160/220), and with around the exact same grading curve. Model predictive overall performance was evaluated with regards to six various evaluation metrics with Pearson correlation and coefficient of determination always more than 0.96 and 0.92, respectively. In line with the results obtained, this study could portray a forward feasibility research
