Currently, due to the growing development of the construction sector in society and the consequences of this demand in the environmental sector, it is necessary to resort to new construction systems in which nature is protected and, at the same time, population demands are met without increasing additional costs. It is known that pervious concrete has low resistance due to the volume of voids it contains, consequently it was proposed to reinforce the pervious concrete with polypropylene fibers to increase the resistance to compression with different percentages of application, and later find the dosage related to the requirements of a concrete applied to pedestrian crossings. As a result, the product dosages of the implemented methods obtained 156 specimens, tested at 7, 14, 21 and 28 days of age, which achieved a maximum result against the compression test of 152.34 kg/cm2 which contains a reinforcement. of 0.075 percent polypropylene fiber, it should be noted that the minimum resistance required was 180 kg/cm2, categorizing pervious concrete as deficient compared to conventional concrete.
