Project description

This research aims to develop a comprehensive methodology for designing and constructing modular roadway bridges. Modularity enhances automation, digitalization, and process efficiency by reducing components, leading to material and waste reductions. Using a limited number of standardized, highly optimized modules—accounting for lifting and transport constraints—enables diverse bridge configurations. Digital manufacturing (3D printing and milling) will facilitate topologically optimized structural elements and dry joint assemblies with concrete. Modular design ensures ease of replacement, repair, and adaptive reuse. The proposed system consists of precast HPFRC segments with dry joints and external CFRP post-tensioning as the sole reinforcement, enabling durable, low-maintenance structures. If needed, non-metallic reinforcements can be used in critical areas. The absence of steel reinforcement allows for low-clinker concrete, significantly reducing environmental impact. Integral design solutions will address vulnerabilities in expansion joints and supports, ensuring structural continuity. High-precision joints between modules will be achieved through digital fabrication, making this system viable for regions with limited lifting equipment. The accelerated construction process minimizes traffic disruptions, benefiting urban environments. This methodology could extend to other infrastructure elements, establishing a new paradigm in efficient, sustainable, and adaptable bridge construction.

Brief description of the Centre/Research Group

The Research Centre is the Structural Laboratory within the School of Civil Engineering (Escuela Técnica Superior de Ingenieros de Caminos, Canales y Puertos). Established in 1802, this prestigious institution was Spain’s sole training center for master-level civil engineers until 1963. In 1971, it became part of the Universidad Politécnica de Madrid (UPM). The School consistently ranks as Spain’s top civil engineering institution and holds a strong international reputation. It is ranked 6th worldwide in Civil Engineering by the Shanghai Ranking. Its bachelor's and master's degrees are accredited by ABET (Anglo-Saxon scope) and EUR-ACE (European scope), ensuring academic recognition across countries. Widely regarded as the heart of Spain’s construction industry, the School has an undisputed reputation for training professionals who have played a pivotal role in the country’s modernization. Its graduates hold key positions in major infrastructure companies, contributing to Spain’s status as a global leader in civil engineering and construction, with Spanish firms operating worldwide.
