Spanish Experience with Concrete Pavements for Airports

Spain can boast of having a very large concrete pavement area, amounting to more than 90 percent in over 35 civil airfields and 5 military air bases. Technical details, construction methods and performance of these pavements are analysed, together with their evolution in the latest projects which have started in the 90's (more than 600.000 m 2 in the last year). Plain jointed undowelled concrete slabs, resting on cement treated or, more lately, on lean concrete subbases are normally used with good results. Some old pavements are still performing well.
