Kentucky Transportation Center Research Report
Major deposits of natural, bituminous, quartz sandstone (Kentucky Rock Asphalt) occur in six counties of western Kentucky and a few minor deposits occur in eastern Kentucky. Crushed rock asphalt has been used extensively in Kentucky and elsewhere for over 50 years for surfacing roads.* The most productive area was in Edmonson County where the Caseyville and Bee Springs formations were quarried and mined.
