| Abstract | Brazil in recent years has grown considerably in real estate, and this has a significant part to the country's economy. This is very important, however the civil construction is an industry that affects the environment, due to the "exploitation" of natural resources, waste of materials in the works, among others. The loss of material along the irregular disposal of civil construction waste (CCW) becomes a challenge for the construction industry to create new mechanisms to recycle these materials and provide application solutions. For this purpose, an experimental study was performed to evaluate the behavior of different percentages of recycled aggregate in the composite with soil through compaction tests, California Bearing Ratio (CBR) and the evaluation of kernel cracking through degradation rates. The used materials were recycled aggregate and soil. With these materials, it was possible to perform physical characterization tests (particle size, true density, Atterberg limits), testing of grain shape with recycled aggregate and mechanical tests (compaction and California Bearing Ratio) with the composites, also checking the grains breakdown postCBR , with and without immersion. The particle size results showed that as the percentage of recycled aggregate in the composite increased, the material became more granular, with higher percentages of sand. The CBR values of materials, with and without immersion showed that the presence of recycled aggregate in the composite increased the CBR and this increase has resulted in an increasement of more than five times (with immersion) and six times (without immersion) compared to the soil CBR value. It was concluded that the samples used have physical and |
