Estabilização de solos com utilização de revestimento asfáltico fresado em camadas de pavimentos

Abstract

Stabilization is a common conduct in civil engineering when it comes to making a soil resource, so the present research aims to do a stabilization of soils with the use of asphaltic residue for use in base layers and sub-base of pavements. The initial phase of the project is a research and exposes the goal. Next, the theoretical reference used in its development is presented, showing all the concepts used. The third section is the closed method, assayed as described and its procedures. Next comes a presentation of the results, classifying them as satisfactory or not. Finally, the conclusion of the research and the suggestions for future work. Initially, the mixtures of soil with milled material in varied proportions, however the result was not satisfactory for the use of floor bases, being necessary another method of fixation to reach such objective. Looking for another solution, it was used as binder material for the accomplishment of chemical stabilization of the soil. Mixtures of soil - lime and soil - asphalt milled - lime residue were tested. The salts of the soil - lime mixture were inconclusive, but that of the mixture soil - asphaltic residue milled - lime obtained the results, they are used in pavement bases with the light level. The project shows that there is a viability of using asphaltic residue in the stabilization of soils for layers of pavements, further studies are needed for its better aplication
