Utilizing data from Colas Északkő Ltd. (andesite quarries), the authors explore the relationships between mechanical and geometrical properties, particularly focusing on the interplay between the flakiness index, shape index, Los Angeles abrasion, Micro-Deval wear, and methylene blue assessments. The presented analysis reveals an unexpectedly robust correlation between FI and SI, proposing a novel paradigm for evaluating grain shape. Notably, the relationship between Los Angeles abrasion and micro-Deval wear values, typically considered disparate, is re-examined, unveiling potential predictive capabilities for environmental wear, especially as indicated by magnesium sulfate soundness testing. Additionally, the current study delineates a significant correlation between methylene blue values and micro-Deval wear performance, highlighting the intrinsic mineralogical influences on aggregate durability. The implications of findings are twofold: they suggest a streamlined approach for aggregate quality assurance and offer strategic insights into the refinement of material selection processes, thereby promising to enhance the durability and service life of transportation infrastructure.

A new segmental steel bridge has been constructed over the Tisza River in Hungary. The bridge comprises of two independent steel box girders assembled by a welding system. Engineers performed proof load tests before opening the structure to evaluate its load-carrying capacity and deck deflection. This paper presents several aspects of the load testing and evaluation of the bridge structure under static and dynamic loads using a rating factor (RF) approach compared to a baseline finite element model. The load test results helped to calibrate the model and verify the method. The study reveals that the tested bridge has an elastic behavior, a high capacity, and adequate dynamic performance.

Nature-based solutions have the potential to alleviate these impacts locally. While a few initiatives have been implemented in Hungary, widespread adoption of these solutions is expected to be a goal for the more distant future.
