Análise de estabilização química de solo siltoso

Abstract

Brazil is a country of continental proportions , so there is a wide variety of soil types . In some regions , the existing soil does not meet the requirements of engineering for its use as a material construction for road bases. This work aims to add a database with information about a chemical stabilizer and reagents ( lime and Aluminium sulphate ), on the matter of the CBR( California Bearing Ratio) resistance relation and the capillarity of a low-quality silty soil ( belonging to group A -4 according to the HRB classification system). Concerning to the CBR, tests were made with 3 doses of chemical stabilizer with 2 types of chemical reagents, the lime and aluminum sulfate. For capillary ;assays with three concentrations of a chemical stabilizer were made in only one type of chemical reagent, the aluminum sulfate. The results for the CBR, despite significant increases were not satisfactory, however, the results concerning to the capillarity had satisfactory results.
