NCDOT's First Concrete Roundabout
NCDOT Project
NCDOT's First Concrete Roundabout
NCDOT Project

Project Location: Edgecombe County, NC (near Carolina Connector multimodal facility)
Size (sq ft): 72,000 (or 8,000 SY)
Concrete Contractor: Granite Contracting, LLC
Dallas Owens, dallasowens@granitecontracting.com, (704) 813-7530
Concrete Supplier: ST Wooten
Owner: NCDOT. Clark Morrison, NCDOT State Pavement Design Engineer developed the required pavement thickness (9.5-inches) for this project.
Attributes: Roundabout constructed of concrete to improve infrastructure resiliency.

Summerfield Elementary School
PRESERVING HISTORY WHILE BUILDING FOR THE FUTURE

Project Location: 7501 Summerfield Rd Summerfield NC 27358

Size (sq ft): 97,917

Concrete Supplier: Cemex

Architect: Vern McKissick Partner in Charge/Carl Kanaskie Project Architect McKissick Associates Architects Winston-Salem, NC

Civil Engineer: Timmons Group

Mechanical Engineer:  Chris Stroupe, CES Engineers

General Contractor: Sammet Corporation

Attributes: 6″ depth – pervious concrete pavement placed on 12″ #57 washed stoneBuilt upon a 8.8 acre site, Summerfield Elementary School consisted of 21 buildings constructed between 1940 and 1985 including 14 modular classrooms. The project was a total reconstruction of the site in order to create a more cohesive flow, provide a more secure environment and allow for future expansion. A multi-story design was developed to reduce the building footprint, while accommodating pervious area. ICF used for envelope.

PCCP and FDR - the Winning Combination
Elizabeth City Airport Ramp Rehab
PCCP and FDR - the Winning Combination

 

Project Location: Elizabeth City, Pasquotank County, NC
Size (sq ft): 225,000 sqft

Architect: Parrish & Partners, Tim Gruebel
Concrete Contractor: McCarthy Improvement Company (McI), Mike Boyle
Concrete Supplier: CRMP, Inc

Engineer: Parrish & Partners, Jeff Kirby, PE (Project Manager) and Tim Gruebel, PE (Design Engineer)
Owner: Pasquotank County Airport Authority
Attributes:

Project Attribute 1
The project was completed in multiple phases that allowed aircraft traffic to be maintained on the airport ramp throughout the
construction process.
Project Attribute 2
The ramp rehab project entailed reclaiming the existing (asphalt) ramp into cement stabilized base material. Approximately, 26,000 SY (or 234,000 SF) of asphalt was pulverized and full-depth reclaimed (FDR) into a P-301 soil cement base material.
Project Attribute 3
The ramp rehab project entailed using 9-inch, P-501 concrete for the majority of the pavement areas. A smaller area near the
airport terminal utilized 6-inch concrete pavement.
Project Attribute 4
Although the engineer (Parrish & Partners) considered four different pavement design alternates; the selected FDR/concrete pavement alternate proved to be the preferred choice when items like longevity, fuel resistance, pavement grades, cost and sustainability were rated and accounted for in the final analysis.
Project Partners: 
Stan Bland, Southeast Cement Promotion Association and Greg Dean, Carolinas Concrete Paving Association provided education to the owner and engineer throughout the design and construction process.

Project Location: 10134 Governors Drive, Chapel Hill, NC
Size (sq ft): 166,104
Concrete Contractor: Granite Contracting, LLC
Dallas Owens, dallasowens@granitecontracting.com, (704) 813-7530
Concrete Supplier: Argos
Owner: Governors Club POA, Roy Thornton
Attributes: 7″ depth – 4,500 psi doweled pavement w/tied longitudinal/curb joints and non-woven fabric overlain an existing concrete pavement. Existing concrete pavement was proof rolled and diamond ground @ raised corner to prevent possible reflective cracking and under rains were installed to aid in future drainage issues.

Laurens County Airport
Pilot Preferred for Landing and Safety
Laurens County Airport
Pilot Preferred for Landing and Safety

Project Location: Laurens County SC
Size (sq ft): 540,000 sqft

Architect: Andy Busbee, Michael Baker International
Concrete Contractor: McCarthy Improvement Company (McI)
Concrete Supplier: Carolina Concrete

Engineer: Andy Busbee, PE of Michael Baker International completed airfield pavement rehab projects phase 1 (2012) & phase 2 (2016)
Owner: Laurens County
Attributes:

Phase 1 project that bid in 2012 contained both asphalt and concrete pavement alternates in the base bid. The bid documents
stated a preference for the 5-inch concrete (overlay) bid alternate for the runway rehab, provided FAA and local funding was
available. The concrete option was the low bid and after the additive bids (and change orders) were included, the project size
grew 50% from the base bid. A total of about 450,000 SF of pavement.

Phase 2 project that bid in 2016 contained only concrete pavement. Unlike phase 1 that bid in 2012, there wasn’t an asphalt
alternate. Portions of TW “A” was resurfaced with 5-inches of concrete. Also, Taxilane 1 was reconstructed with concrete.
Additional available funds enabled the landside terminal parking to be overlaid with concrete. A total of about 90,000 SF of 5-inch
and 6-inch concrete pavement.

Additional Attributes: 

Due to only smaller aircraft (< 12,500#) using this airport, SCDOT 501 spec was substituted for FAA P-501. The concrete strength requirement was changed from 650 psi (flex) minimum to 4400 psi (compressive) minimum and the project savings enabled the additive bids to be incorporated into the final contract. For instance, the airside apron was changed from asphalt to concrete. After the asphalt layer(s) were removed, the in-situ soils were cement stabilized prior to the concrete placement.

Pilots that regularly use this airport have stated their appreciation for the enhanced visibility of concrete on their landing approaches and the coolness of the concrete ramp while performing their pre-flight airplane checks.

Project Partners 
Greg Dean, Carolinas Concrete Paving Association worked with the engineer in the design phase discussing items like the switch to SCDOT 501 specifications and the required joint layout for the thickness of pavement.

I-40 Forsythe County Full Depth Repair
Concrete Pavement Restoration (CPR) Award Winner
I-40 Forsythe County Full Depth Repair
Concrete Pavement Restoration (CPR) Award Winner

Project Location: Laurens County SC
Size (sq ft):  205,200 sqft

Concrete Contractor: David Chapparo with The Lane Construction Corp.
Concrete Supplier: Central Carolina Concrete

Engineer: NCDOT Divison 9
Owner: NCDOT, Pat Ivey

Project Attribute 1
This rapid lane replacement project used the Express Design Build contracting process in order to execute the contract and complete the project as quick as possible. Although 33,100 square yards (SY) of nine-inch concrete pavement was replaced, the portion supplied by Central Carolina Concrete was about 69% of the total (or 22,800 SY). The remaining portions used a concrete
mix provided by a volumetric supplier capable of meeting 400 psi flex strengths within 4 hours. A “rapid set” cement type product was used that enabled high early strengths.
Project Attribute 2
There were a couple different concrete mixes supplied by the local ready mixed supplier, Central Carolina Concrete. One mix met
the required strength (400 psi flex) within 12 hours, while the second mix met the strength requirement within 24 hours. Both of
these mixes used additives to assist with the needed strength gain as well as the needed mix workability. Good communication (24/7) between Lane Construction and Central Carolina Concrete was required to ensure the proper and consistent mix was sent to the project site that met the lane closure times.
Project Attribute 3
The full-depth lane replacements of the 50+ year old pavement were completed at night (7pm – 5am) or marathon weekends (Friday 7pm – Monday, 5am) to minimize traffic delays along this busy interstate route, south of Winston-Salem, NC.

Project Attribute 4
This project was an American Concrete Pavement Association (ACPA) Gold Winner in the Concrete Pavement Restoration (CPR) category during the 29th Annual Awards program, held in Fort Lauderdale, FL. The award was presented to Jim Seybert, The Lane Construction Corp and to Pat Ivey, NCDOT on November 29, 2018.
