RESUMO:

The construction industry is responsible for the high generation of solid waste that is
discarded in nature, contributing to the degradation of the environment. On the other
hand, the construction sector is one of the main components of the Brazilian economy
and its production chain brings together a group of activities that total more than 12
million people, about 13% representing the workforce in the country (FIESP, 2017). At
the global level, the building materials industry is expected to grow by two and a half
times between 2010 and 2050 (UNEP, 2002). In Brazil, the construction sector is
expected to double in size until the year 2022 (CEBEDS, 2009). It is noteworthy that it
is crucial to take measures aimed at the management of solid waste through cultural and
technological changes, aiming to meet the needs of a society increasingly enlightened
and demanding in relation to the preservation of the environment. This work presents a
proposal for the application of construction and demolition waste (RCD) as recycled
aggregates in the manufacture of asphalt coating, as an alternative to the use of these
materials. The work method employed consisted of the collection of residual material in
the company TcPav, carrying out characterization tests in accordance with the standard

standards in the area of paving in the national scope, besides DRX, FRX and dosage by
the Marshall method. Then an experimental section was made using a market trace,
adapted for use with RCD. In this trait was used recycled aggregate containing gravel 1
and sand replacing the same aggregate of the natural type in the coating layer. From the
proposed experimental program it was observed that the residual aggregates had a good
potential of their use in hot asphaltic coatings based on the analysis of the specimens
under the volumetric parameters, the Marshall dosage and the experimental section. As
for the experimental section, it was observed that in the initial months of monitoring a
detachment of the ceramic aggregates present on its surface was observed. However,
such detachment has not compromised to the point of damaging the coating, so that the
asphalt pavement continues to perform satisfactorily the functionality for the vehicles
which travel therethrough.
