In this paper we used construction and demolition waste originating from a central recycling, aiming to elaborate permeable concrete. The objective was to evaluate the influence of the use of these wastes in the mechanical behavior of permeable concrete, with a view to their use in paving urban spaces, focusing on the permeability of the pavement. The work consisted of experimental research, performed the following steps: characterization of the materials used according to specific rules; performing tests to determine the appropriate dash of concrete; performing permeability test using a variable load permeameter; performing tests to determine the coefficient of porosity and performing compressive strength tests. Four models were molded, being a reference and the other with 5%, 10% and 15% of gravel replacement for RCD and the tests were made at the ages of 7, 28 and 56 days. The permeable concrete produced with the construction waste showed satisfactory results, in terms of drainage and compressive strength, achieving appropriate parameters for this type of concrete
