The handmade manufacture of sintered calcinated clay aggregates (ASAC, in Portuguese) is a slow process that it results in small output of material whit discontinuous gradation, fact that indeed hindered the framing of the asphalt mixtures within the granulometric limits used. This work introduces the productive process of said material made in the facilities of a ceramic manufacturer. The raw material is a typical clayey soil of the Urucu-AM oil fields. The natural material, as well as the manufactured sintered aggregates, was validated through the use of DNIT and ABNT - recommended tests. The results proved to be satisfactory having shown that said material is apt to being used in the composition of the asphalt mixture and solving the shortage of stony material in the region, besides minimizing the extraction of natural resources usually employed in the paving services in the region.
