In Florida, asphalt modified racing requires specific technical standards for asphalt or bitumen modification. The asphalt must have a polymer or rubber modifier to enhance flexibility and durability. The surface should maintain a minimum thickness of 1.5 inches and possess a specific aggregate size for optimal grip. Additionally, the asphalt mix must meet temperature and viscosity specifications to ensure proper application and performance during races, adhering to safety and regulatory guidelines set by local racing authorities.
