Abstract

This study uses the CO2 inventory emission methodology in the product and construction phases to compare two construction methods of permeable concrete pavement: the first one using recycled aggregate originated from specimens of the construction of a bridge, and the other, (as a hypothesis) if natural aggregate from a quarry was used. It is pointed that the use of natural aggregates in this type of pavement increases the CO2 emission, when in comparison with the use of construction and demolition waste (CDW) aggregates. Nevertheless, that difference is low when the high emissions by cement are considered.
