Mercer Stone Loading Facility

Location: Harrodsburg, Kentucky

Geotechincal Engineer: Vector Engineers, Inc.
Wall Designer: Vector Engineers, Inc.

Vector Engineers, Inc provided geotechnical engineering
consulting for the design and construction of the Mercer
Stone off loading dock. The loading dock wall was constructed
to allow large rock trucks to end dump shot rock into a large
crusher to manufacture limestone aggregate for use a construction material. The design was unique because the wall facing block was from excess concrete provided by the quarry over a period of years that had been stored on site. The tie back design was conducted by Vector and consisted of using Williams rock anchors drilled into the limestone highwall and secured with epoxy. The top of the wall extended about 40 feet high with the top 15 to 20 feet reinforced with geogrid with crushed stone backfill. The top of the wall and the backfill was covered with a structural slab to allow trucks to traverse the wall for end dumping of product.
