RESUMO:

 

The demand for materials to be used in base and sub-base layers that meet the specifications of road standards in force in Brazil represent a major problem for local road agencies, such as the problem of disposal and use of solid waste. Often the lack of granular materials or their great distance from the construction site of the roads end up making it impractical to use on pavements. Thus, this study proposes to carry out a chemical stabilization study of a soil with cement and ash of Health Services Residues (SSR) as a stabilizing additive, investigating the mechanical behavior of soil-cement and soil-cement-gray mixtures for use on base and sub-base of road pavements. The materials involved in the study will be: a soil characteristic of the Natal / RN region, common Portland cement and ash from the incineration of Health Services Waste. The methodology will involve the study of the materials, with tests of geotechnical characterization of the soil and mechanics of the mixes soil-cement and soil-cement-gray of RSS. The moldings of the test specimens for the soil compaction test and the soil-cement test will be in the normal, intermediate and modified energies and the cement content added to the soil will be 0%, 3%, 6% and 9%. each trait / energy will be molded 3 cp's, totaling 36 cp's in this step. The percentage addition of the cement to the soil will be done in relation to the dry soil mass. With the moisture points taken from the soil compaction curve in the normal energy, 5 cp's will be molded for the CBR test to verify the need for soil stabilization. The addition of RSS ash will be done in percentages of 5%, 10%, 20% and 30% and the percentage of ash will be calculated in relation to the mass of dry soil being molded another 12 cp's.
