Most of the inbound asphalt arrives by rail and is off loaded at a 24-car siding. It takes about a day to unload 24 tankcars.
In-bound tank truck shipments are offloaded at a station on the east side of the terminal.
A well-equipped laboratory is available on site to sample and test asphalt in various blends and formulations.
AOS provides all workers with detection units to check for the presence of hydrogen sulfide in work areas.
Agitators in each storage tank help ensure consistent temperature throughout the asphalt.
A 250-hp Superior boiler provides steam to ensure efficient railcar unloading.
Asphalt Operating Services LLC, Bartlett IL, has developed into a premier asphalt terminal operation. Notably, AOS was the second winner of the International Liquid Terminals Associations' Platinum Safety Award in the small terminal category. AOS currently has 25 million gallons of storage, and there is enough space available to double capacity to meet future demand. A dedicated BP Americas terminal, the facility serves the road construction industry in Illinois, Indiana, Iowa, and Wisconsin.
Pictured are two of four tank truck loading bays at the AOS terminal. Loading is done on Mettler-Toledo digital scales that help serve as overfill protection by shutting off product flow if vehicle gross weight reaches 80,000 pounds. Computerized blending controls make it possible to send customers very precise asphalt blends.
A career veteran of the asphalt terminaling sector with nearly 15 years in terminal management, Joe Shotwell directs operations at the Asphalt Operating Services terminal.
Truck drivers employed by the carriers that haul outbound shipments load their own vehicles, but AOS personnel are available to help as needed. Loading arms are from OPW Engineered Systems.
