Development of Tools in the Quality Management System for the Production and Laying Processes of Hot Asphalt Concrete Mixtures

This article presents the results of developing and testing a toolkit for operational quality management of hot-mix asphalt concrete production based on production monitoring data from an asphalt concrete plant (ACP). The study considers integrating a quality management system with paving and compaction parameters as the next step in developing existing tools. The objective is to ensure that each batch meets customer requirements and regulatory documentation by moving from final result control to management based on process parameter deviations. To achieve this, an information support structure is proposed that integrates the ACP process parameters (dosing, temperature conditions, mixing), laboratory test results, and material data, synchronized using a single batchidentifier. To formalize the management, a vector of batch quality indicators, controlled impacts, and disturbance factors is introduced, and setpoint adjustments are performed iteratively according to the proposed law. Using production control parameters according to GOST 9128-2013 as an example, we demonstrated stabilization of parameters within tolerance limits after a transition section: for bitumen content, with a tolerance of ±0.5% by weight, and for loading temperature within the standard range determined by the binder type. The results confirm the applicability of the proposed approach for the rapid diagnosis of deviations and the selection of corrective actions in batch-by-batch mode.
