The paper presents the basic problem related with practical application of carbonate rocks in construction: are carbonate aggregates produced from such rocks favorable for building engineering, particularly for road design and construction? To resolve this problem, (1) the geological-engineering properties of aggregates are presented, (2) the correlation between petrographic and engineering parameters is shown, and (3) a strict correlation between the geological-engineering properties and the freezing-thawing and crushing resistance is recognized. This knowledge has allowed to assess the usefulness of asphalt concrete (AC) made from dolomite and limestone aggregates in the design and construction of road surface structures. The petrography was characterized using optical microscopy and scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscope (EDS). Engineering properties were determined in accordance with European and Polish norms and guidelines. Statistical and design calculations were performed using dedicated software. The petrographic properties, and selected physical and mechanical parameters of the aggregates, were tested to show their influence on the freezing–thawing and crushing resistance. Strong functional relationships between the water adsorption, and the freezing–thawing and crushing resistance have been observed. Aggregate strength decreased after saturation with increasing concentrations of salt solutions. Calculations of AC fatigue durability and deformation allow for reducing the thickness of the road surface structure by about 20% in comparison to normative solutions. This conclusion has impact on the economy of road design and construction, and allows for a rational utilization of rock resources, which contributes to sustainable development of the construction industry.

Architectural engineering, also known as building engineering, is the application of engineering principles and technology to building design and construction. Definitions of an architectural engineer may refer to an engineer in the structural, mechanical, electrical, construction or other engineering fields of building design and construction; a licensed engineering professional in parts of the United States; in informal contexts, and formally in some places, a professional synonymous with or similar to an architect. Structural engineering involves the analysis and design of physical objects (buildings, bridges, equipment supports, towers and walls). Those concentrating on buildings are responsible for the structural performance of a large part of the built environment and are, sometimes, informally referred to as “building engineers”.

Taking into consideration the complexity of the new, heterogeneous, and different training needs currently present in the classrooms, the school is called to respond them in an effective and concrete way through inclusive educational approaches centered on the students, none excluded. On this basis, the authors, supporting the importance of technology in innovative teaching, propose the design and construction of an intelligent white stick through an inclusive cooperative methodology. The presented device, presented in this paper, is inspired by an open and collaborative teaching, enhancing a responsible digital education, accepting the training needs of all the students present in the classroom, specifically the blind student, and the recognition of the diversity in view of the reduction of disability.
