Abstract:
An intrinsic soil phenomenon is the compacting, gotten with the load application on its
surface. Their effects are harmful to the soil structure but from the point of capacity of soil support, the
actual damages are accented. This way, it becomes important to quantify the compaction levels, in
order to find out the moment where the phenomenon is being more harmful to soil. A way consists of
the analysis of the maximum soil index structural. The index, obtained in this assignment with
compaction gotten in confined environment using uniaxiais pressures with the helping of an
oedometer, allows the construction of a description of the behavior of the soil for applied loads. The
behavior of the structural index is inverse to the application of loads, where to each increase of
pressure, a reduction in the value of the index is had, indicating thus, a greater soil compaction with
inferior values of the maximum structural index. The line compression gotten with the logarithms of
the pressure for structural index are indicative of the soil compaction and allow verifying that the machines traffic is a responsible factor for the compacting. These information can assist to the taking
of decisions during the activities of soil maintenance.
