Evaluación del CBR con la aplicación de polvo de caucho reciclado en material de subbase

Abstract

The research analyzes the physical and mechanical behavior of a granular subbase modified with recycled rubber powder (10%, 15%, and 20%), comparing it with a conventional one. Grain size distribution, Atterberg limits, modified Proctor, and CBR tests were carried out in accordance with applicable standards. The study evaluates changes in density, compaction, and bearing capacity when incorporating rubber, generating comparisons between dosages, and providing criteria for future sustainable applications in road engineering.
