The American Concrete Pavement Association (ACPA) announced winners of its annual “Excellence in Concrete Pavements” awards. McCarthy Improvement received gold in the Industrial Paving category for the CSX Intermodal Terminals project located in Winterhaven, Florida.
Within three years of its initial construction, the Central Florida Intermodal Logistics Facility had outgrown its originally design capacity of 300,000 containers per year. As a result, an expansion project was required and included:
- construction of additional gantry cranes
- high mast lighting
- more than 13 acres of additional tractor trailer parking, loading and unloading areas
McCarthy Improvement was contracted to perform the concrete paving, which totaled 67,000 SY of concrete. The project specifications required a mix capable of attaining a compressive strength of 4,000 psi at 28 days. McCarthy Improvement developed a mixture that met the required strength in less than seven days, which helped expedite cure of adjacent paving lanes. The mix design included Type II portland cement, natural sand and granite coarse aggregates. Even though the granite was not locally available, McCarthy Improvement chose to “rail-in” granite aggregates from eastern Georgia and use them to improve early strength.
McCarthy Improvement completed the paving in 23 days of the 74 calendar days allowed from mobilization to the plant site. The owner previously had issues with roller compacted concrete and asphalt, so the finished project now stands as an excellent example of the versatility and durability of concrete pavements.
