Production and Characterization of Artificial Stone for the Making of Permeable Pavement

In addition to the generation of industrial waste, especially in the ornamental stones sector, another problem caused by modernization which affects urban lifestyle and the environment is soil sealing. The loss of permeability leads in the surface to an increase in water runoff leading to floods, and through channels, to the transferring of these volumes to nearby water bodies leading to problems like silting up of rivers. The present work has the objective of producing permeable pavement using gravel waste in an epoxy resin matrix, and analyzing the feasibility of its use with the characterization of its properties. The slabs of permeable artificial stone were developed with the granite gravel waste having a granulometry between 10 and 20 mm. The characterization was made for porosity evaluation through water immersion, determination of the permeability coefficient and mechanical property. The results were of an (11 ± 1.7)% void ratio of the artificial stone, which indicates low porosity, and with a permeability coefficient of 2 mm/s the material can be utilized as a permeable pavement. The maximum flexural strength value of 4.26 ± 0.08 MPa, above the 2 MPa determined by the standard minimum, this parameter shows that this permeable pavement made with artificial stone has potential to be applied as tiling.
