Caracterización del material pétreo proveniente de la cantera Cuyataza perteneciente al GAD municipal del cantón Sucúa, Morona Santiago

Abstract

In this thesis, an analysis of a stone material extracted from the Cuyataza quarry, which is used in road infrastructure construction, was carried out. However, this material is used without adequate characterization to ensure its suitability for such projects and, at the same time, its long-term durability. For this reason, during this work, different tests were carried out to identify its physical and mechanical properties, such as moisture, granulometry, abrasion, and compaction tests. For this purpose, 16 samples of 4 kilograms were extracted from the quarry to proceed with the material drying, sieving, crushing, and compaction, following the rules established in the standard for the construction of roads and bridges. By conducting this type of test, it was determined that the humidity levels range from 3% to 9%. The granulometry analysis indicates that the material is classified as coarse, due to the significant presence of gravel and sand. Two of the four angularity tests reveal that the material's abrasion does not exceed 50%. Additionally, the compaction tests show that the density falls within the ranges established by the INEN standards. All tests conducted concluded that the material is suitable for use as subbase material within the limitations of the projects that require it.
