Case Study 7: Charlotte Intermodal Facility

Location:
Charlotte, NC
Date:
October, 2012
Product:
AllianceGeo BX Type 2 (300,000 SY)
Engineer:
Patrick Engineering
Contractor:
Milord Company


Application/Problem Description:
Use of BX geogrids to reduce the thickness of a roller compacted concrete (RCC) pavement.

Solution:
The pavements adjacent to the railway lines at this intermodal facility are required to carry the extremely heavy axle loads imposed by various container lifting equipment. Placement of a geogrid at the bottom of the unbound aggregate layer enabled the RCC thickness to be reduced by 3 inches. The geogrid also helped to mitigate the effects of a silty subgrade prone to significant rutting following periods of heavy rainfall.
