Los Castros s/n, Santander 39005, Spain a r t i c l e i n f o a b s t r a c t Article history: In this research, recycled aggregate concretes produced with partial and total coarse aggregate Received 22 April 2013 replacement and control concretes with different increasing water/cement ratios have been cast to study Received in revised form the material’s behavior in response to repeated compressive loads using the Locati method. The results 17 September 2013 show that the methodology can be used to fix the limit interval where the fatigue limit is found. In Accepted 21 September 2013 Available online 1 October 2013 particular, for the same water/cement ratio, the recycled aggregate concrete presents a higher loss of stiffness at the same test conditions. Furthermore, the use of recycled aggregate implies a reduction in the ability to resist fatigue cycles. These differences are increased for low water/cement ra
