Máxima energía de compactación en un suelo granular para afirmado-Cantera Agocucho

The objective of this paper is to show the results of the research Influence of compaction energy on the maximum dry density and optimal moisture content of the granular soil of the Agocucho quarry, Cajamarca - 2017, the granular soil used for road surfacing. Through an experimental design, the tests were carried out varying the compaction energy, with 56, 57, 58, 59, 60, and 61 blows; for each test the moisture content was varied 5 times. Applying the modified proctor method C under the ASTM D1557 standard. For the investigation, it was necessary to determine other parameters such as the optimum moisture content, granulometric analysis, plasticity limits, specific weight and resistance to degradation. The result was that the soil according to the SUCS system is classified as a clayey gravel (CG), and according to the AASHTO classification system it is a gravelly soil with clayey sand A-2-4, maximum dry density of 1.98 gr/cm3 and optimal moisture content of 3.38%, determining that this type of soil reaches its maximum dry density at 28.73 kg-cm/cm3 of compaction energy, by increasing the compaction energy the maximum dry density tends to decrease; It has been stated that each type of soil corresponds to a maximum compaction energy, so special care must be taken in the construction stage to avoid reducing the maximum dry density due to excess compaction energy.
