In this paper, it was performed physical, mechanical, and microscopic analyzes on samples of industrial waste foundry sand (WFS) hot mix asphalt mixtures (HMA) containing WFS as fine aggregate. The HMA produced replacing 50 100 % the aggregate (passing 4.38 mm by sieve) (by weight) with a dense gradation suitable for pavement course layers. A “control” mixture used without WFS. results typical ...
