Characterization of the soils of quarry Number 1 in the province of Ciego de Avila

Abstract

Introduction: In the section of the Central Highway Jicotea – Los Bufalos Bridge, the sidewalks are in poor condition, in some areas below the road grade and up to 0.20m below the edge of the pavement, there are also drainage issues and in some sections the dimensions do not comply with the parameters required in the standards. For their maintenance, it is necessary to use loan materials with appropriate characteristics to be used in transportation works. The quarries that exist in the province with loan materials for these tasks are far from the work, which makes the investment more expensive with transportation costs, which is why the need arises to study new areas such as quarry Number 1, located in the vicinity of the aforementioned area. Objective: characterize the soils of quarry Number 1 for possible use in the growth of walks on the section of the Jicote Central Highway - Los Bufalos Bridge. Method: in the research employs theorical methods such as historical-logical, analytical-synthetic, and systemic-structural-functional; sa well as the empirical observation method; in addition to the statistical-mathematical method of percentage analysis. The AASHTO method is also used for the classification of the quarry soil. Result: based on test carried out on the quarry soils, it was determined that they have a fair to poor quality as a road subgrade. Conclusion: through the studies carried out and the use of appropriate classification methodologies, the quality of the soils can be obtained and thus decisions can be made as to whether or not they can be used as subgrade for roads.
