Posillico Materials began as Posillico Bros. Asphalt back in 1971. An offshoot of J.D. Posillico, the general contractor who first opened its doors in 1946, Posillico Bros. Asphalt (or PBA) operated as a batch plant with 2 silos that supplied asphalt largely to J.D. Posillico for road restoration in association with projects being completed for the Southwest Sewer District from 1971 - 1980.
