Módulo de resiliência de um solo arenoso e de suas misturas com alcatr?o fracionado e cal

摘要

Understanding the resilient modulus (MR) of the sub-grade soils and materials composing the layers of road pavements is crucial for an efficient analysis of their structural behavior as a whole. Due to the importance of the granular materials as layers of flexible road pavements, it has been a practice to determine their resilient response and that of their chemically stabilized mixtures in order to understand their mechanical behavior under repeated loads when used as layers of forest road pavement. This work was conducted to identify the geotechnical and resilient properties of a sandy soil in the county of Vi?osa-MG, in its natural state and after stabilization with lime and tar and to propose empirical correlations between the resilient modulus of these materials and geotechnical parameters easily determined from laboratory testing data.
