SEATTLE - Expect a bumpier drive. An asphalt shortage is delaying road maintenance projects nationwide. Asphalt is becoming scarce as US refiners overhaul their equipment to maximize output of highly profitable fuels such as diesel and gasoline, using inexpensive - and hard to process - crude oil.
To make things worse, refiners are also cutting back on production of a petrochemical that many states mix into asphalt to make roads more durable.
Dozens of road repairs were delayed last summer, and municipalities around the country may face another shortfall next summer. Road-maintenance projects that have gone forward cost significantly more, as the price of asphalt nearly tripled over the past year.
