Ensayo de compactación giratoria en suelos como alternativa al ensayo de compactación proctor

The purpose of this work is to analyze an alternative method for soil compaction in laboratory. The standard laboratory test is known as “Proctor Test”, although research works have recognized that this method does not represent faithfully the real field conditions. In the gyratory compaction test, the process is produced by kneaded which resembles better the effect of the vibratory construction machines. Different tests were performed with vertical pressures between 100 kPa and 400 kPa, maintaining constant the twist angle (1.25o). The material has been tested in different moisture conditions. The results have shown that there are two options to obtain a curve similar to the proctor test. The first way is to work with 400 kPa vertical pressure, 100 turns and 1.25o twist angle. The second way is to apply a 350 kPa vertical pressure, 300 turns and 1.25 o twist angle.
