Kentucky Rock Asphalt (known as Kyrock) is one of the first asphalt road building materials to be used in America. In fact, the Kyrock material was the first material ever laid for the Indianapolis Motor Speedway.
The Kyrock stone is comprised of a very angular (angularity of 47 to 48 degrees) silica sand that is extremely skid resistant. The material qualifies as a Class A polish resistant aggregate which is the most expensive material in asphalt surface mix. The asphalt in the Kyrock varies from 4% up to 15%. The price of virgin asphalt liquid and the quality of the aggregate in the Kyrock combine to make it a large factor in per ton cost reduction.
The Kyrock deposit is located in Edmonson County, Kentucky and has a reserve estimate of over 300,000,000 tons. The property is controlled by the Reynolds Family and was purchased by William G. Reynolds back in the mid 50's. The property is comprised of over 60,000 acres of mineral and mining deeds as well as several thousand acres of surface. The quality of the material and the size of the reserves makes Kyrock one of Kentucky's most abundant natural resources.
