The generation of construction and demolition waste (CDW) has been recognized as a problem in large urban centers, causing problems of preservation of the environment and increase of financial costs. This waste comes from constructions, renovations, repairs and demolitions of civil construction works, resulting from the preparation and excavation of land. This paper shows the good practices to investigate the application of soil stabilization technique with two different CDW granulometric fractions in three different porosities and three cure times (30, 60 and 90 days). The main parameters of resistance control of soil samples (control) and soil-CDW mixtures were dry maximum specific gravity (γd), optimum moisture (ω), CBR, unconfined compression strength (qu) and split compression tensile (qt) for different curing times and porosity. The results indicate that the higher the CDW addition to the soil and the longer the curing time, the greater the resistance increments. The resistance values presented in this research are acceptable for paving works.
