Bitumen is not considered perishable in the same way that food items are. It is a viscous, sticky substance derived from crude oil and is primarily used in construction, particularly for paving roads and roofing. While it can degrade over time due to exposure to extreme temperatures, chemicals, or physical stress, it does not spoil or rot like organic materials. Properly stored, bitumen can remain usable for many years.
