The objective of the present investigation is to determine the influence of the addition of percentages of 16%, 32% and 48% of recycled concrete in the improvement of the physical-mechanical properties of the rigid pavement design, Lima 2022. Quantitative approach research, applied type, descriptive scope and experimental design, in which we worked with a convenience sample composed of 9 cylindrical concrete specimens f'c=280 kg/cm2 without the addition of recycled concrete and 27 cylindrical concrete specimens with the addition of recycled concrete in different percentages according to what is indicated in the NTP 339.034 standard, likewise, we worked with 3 prismatic concrete beams f'c=280 kg/cm2 without the addition of recycled concrete and 9 prismatic concrete beams with the addition of recycled concrete in different percentages as indicated in the NTP 339.078 standard. The results achieved show that the percentage of improvement in compressive strength between the proposed design and the concrete with the addition of 16% recycled concrete is 23%, with the addition of 32% recycled concrete it is 9% and with the addition of the 48% recycled concrete is 3%. It is concluded that the addition of percentages to 16%, 32% and 48% of recycled concrete influences the improvement of the physical-mechanical properties of the rigid pavement design, Lima 2022, since the Student's T hypothesis test regarding the difference in means of the compression test between the proposed design and the concrete with addition 16%, 32% and 48% reported a p value of 0.001, 0.004 and 0.028 respectively, therefore, it is stated that the addition of percentages to 16 %, 32% and 48% of recycled concrete influence the improvement of the physical mechanical properties of the rigid pavement design between 5% and 25% respectively in relation to the proposed design.
