title = "Residue from coal combustion for plastic soil improvement",
abstract = "The combustion of coal in Hoffman-type furnaces generates ash as one of the process
residues. This research seeks to make use of this residue to improve plastic subgrade soils in
tertiary roads, considering that in Colombia a large percentage of these are not paved. A soil with
high plasticity has been selected to make mixtures with ash dosages that vary from 0% to 15%
with respect to the dry weight of the soil. To determine the variation of the physical and
mechanical properties of the soil-ash mixtures tests of consistency limits, compaction tests, and
California bearing ratio were carried out. The results showed that the mixture in which 12% of
the coal combustion residue is added to the soil, as a percentage for the dry weight of the soil,
has a better physical behavior and bearing capacity than the soil in its natural state. obtaining an
increase of up to 75% in the California bearing ratio.",
