Intense population growth brings with it environmental concerns, since exploitation of natural resources, makes it essential to adopt recycling policies in order to achieve sustainable development. Therefore, this study sought to define a new application for recylcling construction and demolition waste (CDW-R). Two size distributions that could be readily prepared in the field were defined for two different samples of recycled waste materials, one basically concrete and other basically ceramic. Tests were performed to simulate conditions of actual use of the materials in the field, and included vertical permeability, confined compression in a hydraulic press, particle size distribution (before and after the confined compression test) and evaluation of clogging by leachate from an existing landfill. The results showed that the CDW-R from concrete are about 80% less deformable than ceramic, indicating that their use in drainage systems is more suitable in this respect. Between samples of the same type, the variation of the modulus of deformability as a function of particle size distribution was 32% for the ceramic waste and 28% for concrete residue, indicating that the deformability of the waste from concrete is less influenced by particle size distribution. It was observed that All samples tested presented a decrease in particle size distribution after the confined compression test. In the leaching test can not be found that there was No clogging by leachate was observed during the evaluation period, but this study should be continued to produce more conclusive results.
