Abstract: Systems and methods are provided for repurposing discarded asphalt shingles as fill material or structural members in building and land surface constructions. Discarded asphalt shingles (DAS) are placed beneath building foundation slabs and parking lots in overlapping patterns to replace a measured amount of removed soil to serve as fill material. Building block system (BBS) units or repurposed asphalt blocks (RAB), may be produced to facilitate handling and transport of the DAS materials to the construction site. DAS can be utilized beneath parking lots by layering the shingles in overlapping patterns to create a moisture barrier from water intrusion from above or below. Repurposed asphalt materials may further be used in the construction of other types of embankments and ground surface constructions to provide both vertical and horizontal support.
