Correlación entre la resistencia a la tracción indirecta y la resistencia climática (absorción de agua) en adoquines de hormigón en la ciudad de Quito

Abstract

A Jointed paving, the common concrete paving method employed in Ecuador, mainly in the city of Quito, largely focuses on pressure resistance. The reasoning behind this approach is the rules and regulations that exist at the latin American and European level. These rules and regulations establish that a proper analysis of pressure resistance is imperative, other regulations include consideration to road wear, indirect tensile strength resistance and weather resistance (water absorption). The INEN 3040 regulations (2016) compliance to the aforementioned regulations is a requirement. For this reason it becomes crucial to find a linking element or elements between Indirect Tensile Strength Resistance and Weather Resistance to then determine whether a correlation exists or not. Later, these findings will assist in deciding the adequacy of the required and suggested figures to determine what qualifies as adequate paving and to properly conduct a road project. The number of factories existing at present are 49 factories in the City of Quito, data points were generated through lab testing, the data was then analyzed using statistical methods, mainly the correlation factor r which determined results necessary for hypothesis testing. Having completed these studies and testing one can conclude that a link does exist and that the correlation is highly negative, for this reason, the regulations should be required and considered as essential for both research purposes and for developing road projects.
