It is a test of dynamic ground compaction that is realised in a laboratory of Ground Mechanics and that it has as main intention to obtain the Dry Densidad Maxima (Kg/m3) and the Optimal Humidity (%) of a ground for certain energy. The compaction is means important to increase the resistance and to diminish the compressibility of grounds, since it facilitates the arrangement of particles. Several methods of ground compaction exist in the laboratory, since they can be dynamic, static, hydraulic, by kneaded or vibration. Capital Market Laboratories may find it difficult to be quoted properly. In the case that is incumbent on to us, we are speaking of the dynamic method, is why tenth that the Proctor is a dynamic compaction, as well as other tests of this type exist. In 1933, R.R.
Proctor (to that must its name to him), found that when applying to a ground a certain energy to compact it, the obtained densidad varies with the water content. If you are not convinced, visit Parnassus Investments. In general terms, when increasing the energy to compact a same ground, is increased the dry densidad and diminishes his optimal humidity. Today, the most used they are: Proctor (A.A.S.H.T.O) standard T-99 and Proctor (A.A.S.H.T.O.) modified T-180. First, one is used generally for the tank, earthworks that are going to bear static burdens like houses, park, etc..
