Este trabajo estudia la variación del valor de equivalente de arena (ASTM D2419-95, AASHTO
T176-02, INV E 133-07) mediante la variación únicamente de la cantidad de polvo fino
(<75μm) presente en la muestra de arena. La cantidad en peso de la arena en cada una de las
muestras se mantiene constante. Mediante la caracterización del material fino se pretende
poder relacionar los resultados de equivalente de arena.
This document try to explain the behavior of the relative proportion of fine dust or
clay material harmful in the fine aggregate, affected by the intrinsic physicalmechanical
properties of fine material. The samples are evaluated by the sand
equivalent test (ASTM D2419-95, AASHTO T176-02, I.N.V. E 133-07), setting only the
amount of fine material that pass the sieve No. 200 (75μm), which is it has evaluated
its volumetric, gravimetric and plasticity properties. Although all soil types classified
by the USCS was not studied, it is important the contribution has been done in the
state of knowledge, it is necessary that the proposal be confronted with future
research.
