Materials are the raw material of construction, since ancient times there have
been various materials for construction and its use varies depending on the
demands of the work to be built since each material used has different physical
and mechanical properties, however, not all materials are friendly to the
environment, some of them produce pollution from the time of its procurement
and processing. Many are obtained from nature directly and some others are
made by the human being. That is why we have entered into this line of
research in which we propose the use of recycled materials specifically waste
products from the construction and demolition of hydraulic concrete roads,
buildings and buildings that have reached the end of their useful life, for
reincorporate them to a new life cycle within the construction of asphalt
concrete pavements, substituting a percentage of 20% of natural petrous
aggregates for this construction and demolition waste. This technique provides
both economic and environmental savings. The environmental saving is
generated from the moment of replacing a material of natural origin with a
recycled one since to obtain this material an indiscriminate exploitation of
materials bank, change of land use and change in the ecosystem of the place is
required, which generates a deterioration to the environment. The design was
carried out with 20% substitution and comparable results were obtained with
the design of the control mixture elaborated with 100% natural petrous
aggregate, however, the mixture with 20% of recycled aggregate generates an
environmental and economic saving, fulfilling with the requirements set by the
regulations for design transit. It is worth mentioning that both mixtures were
designed for a roadway of normal specifications according to the guidelines of
the SCT with the Marshall design methodology established by the same
secretary which analyzes aspects of stability and flow to obtain the optimum
percentage of asphalt.
