FDOT Code 30 (Limestone #67)
Also known as: Code 30, trench bedding rock, Code 30 bedding stone, utility bedding aggregate
FDOT Code 30 bedding stone is a clean, crushed limestone aggregate that meets Florida Department of Transportation (FDOT) specifications. It is typically sized between 3/8 inch and 3/4 inch with little to no fines, which makes it ideal for drainage and consistent support in underground work. This material is commonly used for utility bedding, pipe installation, trench backfill, drainage systems, and roadway construction projects where you need stable stone that won’t trap water or compact like a fines-heavy base. With its uniform sizing and durability, FDOT Code 30 provides reliable long-term performance for both municipal and commercial construction.
