Norfolk Southern Charlotte Regional Intermodal Facility
Charlotte, North Carolina

Contractor: A. G. Peltz Group, LLC
Owner: Norfolk Southern Railway Company
Engineers: Patrick Engineering / The Milord Company

This project at the Charlotte Regional Intermodal Facility consisted of 26,977 SY of 17 in. roller compacted concrete (RCC);  20,310 SY OF 10 in. RCC; and 232,352 SY OF 9 in. RCC pavement.

Using their in-house blending programs, A.G. Peltz Group, LLC  developed an optimized blend of three aggregates and 14.5% cement content, achieving compressive strengths exceeding 5,000 psi and 650 psi flexural strengths at 28 days.

The contractor used high density paving machines with paving widths ranging from 18 ft to 29 ft.  Paving machines were fed by natural transfer devices so that a contactless, uninterrupted material supply could be achieved, with enhanced pavement smoothness and quality.

A.G. Peltz implemented a maximum 15-ft. joint spacing plan to reduce slab lengths and improve load transfer at the joints, thereby reducing the opportunity for mid-panel cracking.

The Intermodal Facility’s yard is currently operating at near capacity with no significant RCC-related pavement issues noted to date.   The owner also has since specified the use of RCC pavement for additional container terminals.
