To ensure correct blending, AOS contracts with an independent testing laboratory, PRI Technologies, to perform testing and grading of each batch of asphalt they blend. PRI leases space from AOS to maintain their laboratory onsite but remains completely independent in order to ensure the integrity of their testing. Samples from each batch are also maintained by PRI and various independent testing agencies and state regulators periodically request samples to be tested in their own labs.To keep the asphalt from solidifying in the large storage tanks, it must be continuously heated. To accomplish this, oil is circulated through a closed loop system and heated to between 300 and 400 degrees Fahrenheit by one of two heating units. The heated oil is circulated through coils that are contained inside each storage tank.
Currently, the AOS terminal ships its finished products by both rail tanker cars and by truck. Approximately 12 thousand trucks and 9 thousand rail tanker cars may leave the facility each year and the AOS facility was built with an eye to greatly increasing capacity if demand warrants.<< previous 1 2 3 4 5 6 next >>
