Aggregate backfill in Milwaukee's Third Ward
A dump truck is raising its box, about to unload aggregate at a construction project on the east side of the 200 block of North Broadway in Milwaukee, Wisconsin.
The sidewalk vaults ("hollow sidewalks" - open space beneath the sidewalks) are being filled with aggregate, because of the age and condition of the iron beams that supported the sidewalk.
The aggregate will be spread out by a skidsteer loader and hand shovels, then compacted with a plate compactor.
