    The utilization of local materials is presented as an efficient alternative, facilitating the production of high-quality pavers that play an essential role in urban development. This strategy contributes to establishing a technical foundation, enabling the development of solutions in the construction sector, fostering economic growth, and enhancing the social well-being of the communities involved. The research was conducted using an experimental approach, evaluating the physical and mechanical properties of the materials based on the INEN 872 standard. In this phase, key characteristics such as granulometry and density were analyzed to ensure their compatibility in mixtures. Subsequently, a procedural manual was developed, detailing guidelines for executing the activities. Next, the mix design for the paver production was carried out based on the ACI method, where test cylinders were subjected to compression tests, yielding results of 60.77 MPa and 60.99 MPa at 28 days, indicating that the mix design is optimal. Following this, the paver mix design with a tensile strength of 30 MPa was developed, and as part of quality control, tests were performed according to the NTE INEN 3040 standard, yielding satisfactory results. Finally, it was concluded that the mix design was successful, as the average results for the indirect tensile strength of the pavers reached 3.604 MPa, demonstrating that this experimental work promotes an efficient construction model.

    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.
