Abstract: In this research, different mixtures under fatigue loadings using the Locati steps or the increasing amplitude test method have been studied. Control concretes with natural limestone aggregate and recycled aggregate concretes with substitutions of 20%, 50% and 100% of coarse natural aggregate by recycled aggregates coming from concretes have been analyzed. Results show that the Locati methodology can be used to obtain a good approximation of the limit interval where the fatigue limit. Furthermore, the use of recycled aggregate implies a reduction in the number of cycles able to resist. These differences are increased for low water/cement ratios, as in this case the main factor is the lower strength capacity of the aggregate.
