In Brazil, the transport matrix has an expressive participation of the road
modal, which concentrates around 65% of the movement of goods and 95% of
passengers. To ensure the conditions of circulation with comfort and safety, the
municipal, state and federal agencies perform maintenance and restoration services
on the highways. With the execution of these services, a quantity of residue is
produced that generally does not have an adequate environmental destination. One of
the residues generated is the RAP, generated by milling the asphalt coating, and this
material is commonly taken to the plant or land of the companies that perform the
service for public agencies, being stored and conditioned for possible future reuse.
This work aims to study the reuse of milled asphalt sidewalk material from
milling the streets of Manaus. In this study, the aggregates and the petroleum asphalt
cement (PAC) were analyzed, coming from the recycled material and removed through
the maintenance services of the city streets, through laboratory analysis and tests
according to the Brazilian standards (NBR) corresponding to each material used for
the production of asphalt coating. It was also analyzed through the Marshall Mixing
Method for the production of the asphalt mixture for conventional CAUQ and with the
addition of a percentage of RAP in the mixture, comparing the results obtained in the
laboratory and in the field, by providing the results of ARDO Construtora of its
technological tests, in the interest of comparing the results and ascertaining whether
the addition of milled material in the composition of the asphalt material is sufficient
and meets all the parameters required by Brazilian standards, thus providing a new
destination for the recycled material and enhancing the care with environmental issues
and generating possible savings in the production cost of asphalt mix.
