The group studies this type of mixes with both natural aggregate (conventional quarry aggregate) and recycled aggregate from road milling (RAP). In particular, the group focuses on solving the main drawbacks of these technologies, such as shortening their maturation period or deepening the knowledge of their mechanical properties.

These are mixtures that help to collaborate with sustainable development by reducing CO2 emissions into the atmosphere, as well as other gases responsible for global warming. The objective of this line of research is to deepen the knowledge of the dosage and properties of these mixtures, with high performance but lower manufacturing temperature.

The objective of this line is to analyze the possibility of using wastes in the manufacture of different asphalt materials (e.g. cold asphalt mixes, hot asphalt mixes, etc.) and to see how they affect their behavior. The ultimate goal is to avoid the depletion of natural resources, as well as to avoid landfilling valuable materials.

Consists of the use of modifiers or substitutes for asphalt bitumen and its derivatives, obtained from biomass or industrial co-products of vegetable origin (e.g., co-products rich in lignin, cellulose, etc.).

Incorporation of nanomaterials (nanocellulose, nanoclays, nanosilica, etc) to bituminous mixtures and other materials for road pavements, in order to improve their mechanical properties.

Research on causes and/or points of accident concentration, both on current highways and roads and in the future with intelligent vehicles. Analysis of the human factor and driver assistance systems in vehicles. Design of strategies in line with Vision Zero.

Study of the problems of tunnels excavated by any procedure (Belgian method, Austrian method, with tunnel boring machine, etc.), and of any other type of subway excavation (enclosures between screens, Metro stations).

Study of secondary consolidation in muddy soils, very frequent in port works.

Study and analysis of all types of geotechnical works by means of numerical models: shallow and deep foundations, geotextiles, land treatments, embankments, slope stabilization, etc. The programs used are FLAC3D, PLAXIS 3D, GEOSTUDIO, PFC3D, 3DEC, RIDO.

Study of wave propagation in the ground and its relation to the stress-strain behavior of soils. Soil damping. Study of ground vibrations caused by railway traffic: surface and subway lines. Study of vibration reduction measures based on ground inclusions. Computational models formulated in the time/space domain for the study of wave propagation in the ground.

Study of soil behavior as a function of the deformational state and its relation with constitutive models of soil behavior. Application of advanced constitutive models to different geotechnical problems: screens, railway vibrations, tunnels, foundations, etc.
