| Resumo: | Government efforts have found some obstacles in achieving a better
infrastructure regarding environmental preservation requirements. There is a need to
develop new techniques that leave the big exploitation of environmental resources.
This study measures the evaluation of the behavior of a composite formed by lateritic
soil mix and tire buffings. In this way, a road embankment model was developed to
assess the bearing capacity of the composite. This study measured the load capacity
of the composites with 0%, 10%, 20% and 40% rubber mixed with the soil, by weight,
iron plate loading tests on a simulated embankment in a metal box of 1.40 x 1.40 x
0.80 m. After four compaction layers of the composite, a plate test was performed, and
then stress-settlement curves were obtained for the material. The embankments with
20% and 40% rubber content was difficult to compact. There was a significant
reduction in the load capacity of the soil-plate system with increasing rubber content.
The composite with the lowest loss of bearing capacity in relation to the reference soil
was the one with a χ = 10%. In the load capacity tests, another aspect noted was the
bearing capacity in terms of CBR. The results also show a gradual decrease in bearing
capacity in the composites as with the rubber incorporation content increases. As in
the plate load tests, the composite that had the lower bearing capacity loss was also
that with 10% content. |
