The waste from construction and demolition of civil works (CDW) represents the majority of the volume of waste that is generated in large urban centers, and it is necessary that an appropriate destination be carried out to mitigate the environmental impacts and the social problems that they cause. Based on these factors, several researches were carried out in different regions of Brazil and the world in order to use this residue as an alternative material in paving works. Given this context, this work aims to analyze the use of CDW associated with different types of soils from three regions of the state of Rio Grande do Norte, aiming at its use in paving works. The experimental program was carried out using CDW samples obtained from a private company, and soil samples extracted from three large regions in the state of Rio Grande do Norte. The laboratory investigation methods were based on physical characterization, compaction, CBR and grain break analysis tests. For that, the percentages of CDW of 25%, 50% and 75%, by mass, were added to the soils, in order to verify the benefit that this increase can cause in the characteristics of the materials. The results obtained show that depending on the percentage of residue and the type of soil, the increase of CDW to the soil causes the CBR values to rise and improve the properties of the samples. Thus, the replacement of part of the natural material by CDW is a potential alternative for application in paving works.Acesso AbertoRCDCBRPavimentaçãomasterThesisCNPQ::ENGENHARIAS::ENGENHARIA CIVIL
