Estudo da estabilização de um solo para fins de pavimentação na região de Campinas – SP

Abstract

Soil stabilization is a technique widely used in paving works, especially in situations where the change of soil to the lower layers of the pavement becomes an economically or executively unfeasible option. The work in question aimed to study the improvements obtained with the chemical stabilization of a soil, collected in the region of Campinas in the state of São Paulo, using the biocatalyst Earth Materials Catalyst Squared and what would be the best use for this material in paving services. Particle size analysis, liquidity limit and plasticity limit tests were performed for soil classification. The determination of the California Support Index was performed before and after the application of the biocatalyst. It was concluded that the studied soil presented an improvement in its resistance after the use of Earth Materials Catalyst Squared, however, it still did not present satisfactory results for the use in some layers of flexible pavements, being indicated its use only for subgrade reinforcement layers.
