Abstract
The current trend toward the use of 3D concrete printing represents a vector for green financing of innovative transportation projects and a shift from traditional construction to additive manufacturing and a closed-loop economy. The potential impact of additive technology in the field of transport infrastructure is expected to be greater than in any other, due to the scale of construction printing and its environmental potential to ensure the environmental safety of transport construction at the global, regional and local levels, which appears to be a relevant interdisciplinary research area. The article analyzes the transition to a "green economy," including the introduction of additive technologies and the rational use of construction resources. The article gives proposals for energy-efficient and ecological green construction of high-speed railways and provides a rationale for the use of additive technologies using 3D-printed noise protection walls made of eco-concrete (green concrete, geo-concrete). The main recommendations on the choice of structures, optimal for the implementation of active noise protection measures on high-speed railways and artificial constructions are given. Presented the work of PSTU students of the Faculty of Transport Construction on the subject of 3D printing of noise protection panels with different acoustic performance. Modern architectural solutions were made with the preparation of a feasibility study on the implementation of innovations and the development of green design competencies.
