Caracterização de Solos Lateríticos e Saprolíticos para Pavimentação de Baixo Custo

Abstract

This article discusses the technical characteristics and discusses the comparative analysis between two types of tropical soils to be used in Brazilian paving. Demand for paving is directly related to increased traffic, making it necessary to increase paved roads. Soil, as the main constituent material, must have ideal characteristics to perform its function in each layer. The purpose of the comparison presented in this paper is to check the mechanical and geotechnical properties of each material in order to benefit the low cost paving. Therefore, two types of expressive soils were adopted: lateritic and saprolitic, both extracted from natural deposits. The first material was taken from the banks of GO 230, at km 13, in Itapuranga-Go. Already the second in the nook sector of the general mines, in the city of Goiânia-Go. To obtain the data presented in the study, laboratory tests were performed according to the Brazilian regulatory standards. After the analysis of these indicators it was noticed that the lateritic soil properties stand out in relation to the saprolitic soil properties. In addition to the results obtained, it is necessary to subject both soils to further tests that deepen the characteristics of each soil for application to the pavement.
