The technological characterization of aggregates is essential for paving works, as it measures
the properties and helps to predict the behavior of the aggregates in the asphalt mixture, when
in service. However, it is not always possible to make this characterization in all works, since
the great distances, absence of environmental zoning, precarious access conditions and
unavailable infrastructure, limit the process of extraction and direction of the aggregate for
consumption. Thus, technological characterization studies should be carried out in order to use
mineral aggregates closer to the consumption centers of the works. Therefore, the objective of
this work is to characterize the aggregates: gravel 0, stone dust and natural sand used to compose
the asphalt concrete of the flexible pavement of the BRT work in the Metropolitan Region of
Belém on the BR-316 highway, according to specifications indicated by DNIT standards. To
this end, the tests of particle size analysis, shape index, Los Angeles abrasion and specific mass
of coarse and fine aggregates were used. The main results were: "Los Angeles" abrasion = 34.11
%; form index = 2.165; Specific mass of aggregates: gravel 0 = 2.658 g/cm3, natural sand =
2.625 g/cm3 and stone dust = 2.638 g/cm3 ; particle size analysis: Gravel 0 has an open
graduation with continuous granulometric distribution, natural sand has a dense graduation with
continuous granulometric distribution and stone dust has a dense graduation similar to natural
sand. The best proportion of aggregates, according to the trial method, to reach the "range C"
of the DNIT was 60 % of crushed stone 0, 25 % of stone dust and 15 % of natural sand, with
specific mass of the aggregate mixture = 2.648 g/cm³. Therefore, it is concluded that the
aggregates meet the DNIT specifications for the "C range" of asphalt concrete (AC).
