FundingsThe Project has been co-funded by the Ministerio de Economí­a y Competitividad in the Call Restos-Colaboración 2015 and by the European Union through FEDER funds under the objective of promoting the technological development, innovation and high quality research (Promover el desarrollo tecnológico, la innovación y una investigación de calidad)
SummaryThe durability requirements established in the project of important infrastructures has become increasingly severe in the last decades. Nowadays, it is common to find design specifications that include a minimum service life between 100 and 150 years. The project DURADOV focuses on the development of tunnel segments with non-metallic fibre reinforced concrete (NMFRC) that fulfils demanding durability and sustainability requirements. Among the main objectives of the project are: - Design and characterization of alternative NMFRC suitable for application in tunnel segments subjected to typical soil types, depth of excavation, construction loads, etc. - Study the durability of the NMFRC, seeking for materials capable of guaranteeing a minimum service life between 100 and 150 years. - Evaluate the behaviour of the NMFRC segments when subjecting to fire actions. - Develop new quality control methods for the assessment of fibre content and orientation in NMFRC. - Develop new methodologies for the structural design and estimation of partial safety factors taking into account the specificities of the NMFRC and the application in tunnels.
