In 2009, 105 single-family homes in the city of Cordoba were demolished in order to expand the airport. At first, the debris from the demolition was going to be sent to a landfill, as is common procedure. But, the University of Cordoba came up with the idea to recycle all the debris in situ and use it to build an experimental stretch of road on the CH-2 highway that goes around the runway at the airport and also connects Cordoba with the town of Almodóvar. This stretch of road is used by over 9,000 vehicles on a daily basis. After ten years of research, the complete study was published. The results are very positive and the conclusion is that recycled materials from demolitions are a good alternative when building roadways.
