Arroyo de Las Piedras viaduct is the first composite steel-concrete high-speed railway viaduct in Spain. The viaduct is located in the South of Spain, on the High-Speed Line between Córdoba and Malaga. The structural form is a continuous beam with 20 spans. It is about 1,2 km long: 17 spans are 63,5 meters long and the remaining 3 are 44, 35 and 50,4, meters long. The height of the piers is up to 93 meters and above, which is remarkably high. The cross-section of the deck is made up of two 3,85 m deep twin-plate girders plus a top slab 14 m wide, whose thickness varies from 0.41 m in the deck’s longitudinal axis to 0,22 m at the edge of the overhangs. The result is a composite steel-concrete cross-section with a constant total depth of 4,26 m.

Object analysis
Due to the viaduct’s height, the inspection and maintenance tasks are very difficult, dangerous and costly. Therefore, the interest lies on evaluating new inspection methodologies that can reduce the complexity and risks of these inspections while improving the quality of the inspection data, not only visual but also precise geometrical data that can be used for precise structural assessments of this infrastructure.
Object state
No deterioration processes or damages are reported. The aim of the case study is to evaluate and develop new inspection methodologies, such as the use of drones and robotics, for inspection and maintenance purposes.
