<description>Infrastructure quality control must be done through an adequate control process, which&#xd;
must be well planned, programmed and executed. It implies the revision of the specific&#xd;
control procedures as part of the general objective of continuous improvement. It must be&#xd;
applied to the construction of quarries with stone materials, called rockfills for large sizes&#xd;
or random fillings for intermediate products. There continues to be a problem in terms of&#xd;
compacting control methods in the execution of these diggings, with little practical&#xd;
development of new techniques when the spread is of good – quality material an aspect&#xd;
that must be revised in order to ensure the quality of the final result extended and&#xd;
compacted. The current procedures for Quality Control in rock compaction have limited&#xd;
operability. For example, the granulometric analysis with macro-pits (4m3) it is have done&#xd;
with heavy fractions, being a destructive testing. The average density control by nuclear&#xd;
methods has high heterogeneity, low performance and low thickness tested. The&#xd;
topographic measurement settlement is the most accurate, but it is a poorly referenced&#xd;
method. For the wheel impression test, the required values do not impose any limitation.&#xd;
This research studies the application use to granites, slates and granitic alteration soils&#xd;
stabilized using cement. The necessary field and laboratory works were developed in order&#xd;
to elaborate new test procedures for a proposed compaction control in rocks. The&#xd;
compaction control procedures revised were wheel impression test, topographic settlement&#xd;
and plate load test (PLT). Doing simple regression on SPSS, in which any predictor&#xd;
outcome variable (dependent) should be placed (independent). An analysis of variance&#xd;
ANOVA shows the sums of squares and the degrees of freedom associated with each: is&#xd;
significant at p &lt; 0,05. There is less than 0,5% chance that an F Levene – ratio this large&#xd;
would happen if the null hypothesis were true.</description>
