Análisis comparativo de la utilización del método de cono y arena y densímetro nuclear para determinar densidades de campo en suelos cohesivos para terraplenes y vías procedente de la cantera ubicada en el km 19.5 de la carretera Guayaquil-Salinas.

Abstract

Thanks to technological advances, AASHTO and ASTM have been able to develop new methods for taking field tests, as happened with the invention of the nuclear densimeter, to the detriment of the traditional cone and sand method, when taking relative field densities. In this work, we sought to determine which of the two tests is the ideal to meet quality standards, also prioritizing time and costs. To carry out this analysis, ten tests were taken with each method in one of the roads of the CostaSol urbanization, at Km. 19 of Vía a la Costa, in Guayaquil, Ecuador, comparative graphs of the results of density and humidity, and Theoretical-technical comparisons of the two methods were made, being able to confirm that there were no major technical differences, but that the advantages in time and cost are so favorable for the nuclear densimeter, that it is definitely the most recommended test for all road works.
