Limestone in Florida's peninsula plays a major role in transportation. As a road surface, a base layer, or as aggregate in asphalt and cement concretes, most road building projects require large quantities of limestone. Millions of tons of Florida limestone produced annually go into transportation projects. However, limestone properties can vary considerably. Therefore, the Florida Department of Transportation (FDOT) has established minimum durability requirements for limestone aggregate, which all limestone used in FDOT projects must meet. Limestone meeting these requirements comes from only a few regional locations, notably west Miami-Dade, Lee, and Taylor counties, and the supply is finite. The desire to conserve existing reserves as long as possible prompted the question of whether top quality limestone should be required for all transportation purposes.
