Fines characterization through the methylene blue and sand …
In road construction the general term fines is used to describe particles passing the 0.063, 0.074 or 0.08 mm sieve. Some types of fines are considered to be relatively inert and have almost no effect on pavement performance, whilst the presence of even small amounts of others can significantly affect the stiffness and freezing–thawing behaviour of unbound and …

TESTS FOR PLASTIC FINES IN AGGREGATES RELATED …
Six fine aggregates were chosen to give a wide range of mineralogical compositions and sand equivalent values. In addition, four fine aggregate blends were made to produce a wider range of sand equivalent values. These fine aggregates were obtained by blending a high plasticity clay with fine aggregates PF-4 (Granite) and PF-6 (Limerock).
