Design of a concrete f’c =175 kg/cm2 and f’c =210 kg/cm2 with rigid pavement rubble, San Martin Region In the current thesis project it was determined that the physical-mechanical properties of recycled coarse aggregate, fine aggregate (Cumbaza sand) and coarse aggregate (Huallaga stone) are within the technical specifications described in the ASTM standard. When calculating the dosage using the ACI Method for the mix design F'c=175 kg/cm2, the results showed that the C/A/P/A ratio is 1 bag/2.40ft3/3.20ft3/3.20ft3/26,10lt, of which 15 samples were made with a 7-day cure, which reached an average resistance of 153.04kg/cm2, 15 samples with a 14-day cure reached an average resistance of 166.31kg/cm2 and 60 samples with a 28-day cure reached an average resistance of 170.60kg/cm2, which represents 97.48 % of its total resistance. The conclusion is that the presented dosage is optimal due to the fact that the standard deviation is <0.05 and for the mix design F'c= 210kg/cm2. On the other hand, when the C/A/P/A ratio was 1 bag/1.80ft3/2.50ft3/20.90lt., 15 specimens were made with a 7-day cure reaching an average resistance of 133.65kg/cm2, 15 specimens with a 14-day cure reaching an average resistance of 158.59kg/cm2 and 60 specimens with a 28-day cure with an average resistance of 188.11kg/cm2 which represents 89.58 % of its total resistance, leading to the conclusion that the dosage presented is not optimal due to the fact that the standard deviation is >0.05, thus requiring a readjustment of the dosage.
