Resumen:

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.
