In a storage dam construction an impervious element is required either
in the core or face thereof. For this purpose, have been used different
systems and materials in order to meet the required low permeability,
the more common systems has been clay cores and concrete facings.
Occasionally and mainly due to economic reasons other alternatives have
emerged with highly satisfactory and competitive performance, an example
of this is the use of asphaltic concrete cores and faces. Asphaltic
concrete is a material made of mineral aggregate and asphalt in
proportions dosed at will, varying these proportions can be controlled
large number of physical parameters, including permeability. This paper
shows the influence of asphalt content, the particle size distribution
and quality of aggregates in the permeability of the asphaltic concrete
to be used in waterproof barriers of dams.
