Estabilización de subrasantes mediante el sistema arena emulsión asfáltica

Abstract

In the present investigation the application of the cationic asphalt emulsions, used in the stabilization of subsoil sandy soil, was carried out, in which the verification of parameters such as; Resistance to uncompressed simple compression, indirect tensile test, soil support value (CBR), triaxial test, as well as permeability verification, results that allow to characterize the sand-emulsion mixture. For the development of the research was used sand from the sector "Shucos" of the city of Loja, as well as asphalt emulsion of the cationic type of Slow Break (CSS-1 h), provided by Chova del Ecuador (Quito). The concept of useful life of the road works and the consequent need to estimate the durability of the materials, forces to put true emphasis on the quality control, therefore a revision of the asphaltic emulsions is made, taking into account the importance that these are Have in the modern technology of the asphalt road process.
