A country development indicators, are associated with the population's basic needs' satisfaction and other complementary needs, such as those related with the roads infrastructure, that promotes the regions'competitiveness. In some developing countries, it is marked the paved roads'low percentage, with the consequent economic impact, affected by the connectivity's low level. For this reason, it is necessary to implement some projects which can improve the roads' conditions, with alternatives that protect the sub-base layer stated. The stone's slabs that can be installed as an articulated pavement, becomes a viable alternative, in those territories where the stone is abundant. The Barichara, municipality of Santander (Colombia), is an area characterized by its stone's quality, which is extracted manually, and used for decoration and as a coating material. The stone's extraction process has two problems: On the one side, it affects the people involved in this work's health, on the other hand, it generates a byproduct with a negative impact in the landscape. This study shows that the crushing residue obtained after the stone extraction process, allows a usable item (residue's) generation for the concrete mixtures, both for the footpaths, and as a mortar for the tiles in a low road traffic area.
