Associated Asphalt Greensboro

Associated Asphalt Greensboro is a liquid asphalt terminal serving contractors, hot-mix producers, and public agencies across the North Carolina Piedmont. Located on Chimney Rock Road near Piedmont Triad International Airport, the facility is part of Associated Asphalt, one of the country's larger independent asphalt terminaling, storage, and distribution companies, and operates as part of the Ergon family of companies within Ergon's Pavement & Coating Resources segment.

Rather than performing paving work itself, the company supplies the binder that paving contractors and asphalt plants depend on. The Greensboro terminal stocks paving-grade performance graded (PG) asphalts including PG 58-28, PG 64-22, and PG 76-22, along with liquid antistrips and warm-mix additives such as Morelife 5000, EvoTherm M1 and U3, and LOF 6500. Loading hours run around the clock Monday through Friday, with Saturday loading available, allowing hauling schedules to be built around night paving and early-morning plant startups.

Greensboro holds a notable place in the company's manufacturing network. The terminal was acquired in 2004, and in 2011 the site was developed with polymer-modified asphalt (PMA) production capability, making it a regional source of modified binders as well as conventional PG grades. Across its broader product line, Associated Asphalt supplies SBS polymer-modified binders formulated to resist rutting, fatigue and thermal cracking, reflective cracking over concrete pavement joints, and bridge deck movement; Ground Tire Rubber hybrid asphalt that combines SBS performance with recycled rubber; fuel-resistant binder meeting the FAA's P-404 specification for airfield pavements exposed to jet fuel and slow-moving aircraft loads; thin-overlay mix systems that can reduce or eliminate milling; void-reducing asphalt membrane for longitudinal joint durability; and racetrack-grade binder engineered to a specific softening point.

Emulsified asphalts are another core category, produced at company plants in Bristol and Roanoke, Virginia; Columbia, South Carolina, through SEACO Asphalt Emulsions; and Tampa, Florida. These products support pavement preservation and roadway maintenance work such as fog seals, chip seals and other bituminous surface treatments, prime coats, conventional and non-tracking tack coats, cold in-place recycling, and full-depth reclamation. Cold mix is produced under the Colprovia brand, which is operated by SEACO.

Technical support is handled through Bituminous Technologies, LLC, the company's laboratory division doing business as BT Lab. It performs product research and development, quality control, and third-party testing at two laboratories accredited by the American Association of State Highway and Transportation Officials.

Supply reliability is built on scale and logistics. The company operates roughly 30 land- and water-accessible terminals throughout the Eastern United States, with 17 land-based liquid asphalt terminals connected directly to Norfolk Southern or CSX rail lines. Product moves by rail, barge, truck, and time-chartered vessel, and Associated Asphalt Transport, LLC provides dedicated hauling from several terminals. Florida terminals with port access at Tampa and Miami support bitumen export shipments to Caribbean markets.

The business traces its roots to 1948 in Roanoke, Virginia, where it began as Fuel Oil & Equipment Company. Liquid asphalt sales started in the 1960s, non-asphalt lines were divested in 1997 when the current name was adopted, and the terminal network expanded steadily through acquisitions and greenfield development before Ergon Asphalt & Emulsions acquired the company in December 2023. Corporate offices remain in downtown Roanoke.

Typical end uses for material shipped from Greensboro include highway and interstate construction and resurfacing, bridges, municipal streets, parking lots, and airport runways.
