About this file
This is a specifications document for an aggregates contract with the Louisiana Department of Wildlife and Fisheries (LDWF), RFx 3300026281. The document outlines detailed technical requirements for six categories of rock and aggregate materials to be supplied. Rock 1 specifies #610 Limestone with defined gradation requirements ranging from 1-1/2" down to #4 sieve sizes, maximum density of 134.8 lbs per cubic foot, optimum moisture of 7.7%, and Los Angeles Abrasion Grading A with 29% loss. Rock 2 defines #57 Limestone with gradation from 1-1/2" to #8 sieve sizes, bulk specific gravity of 2.64, and Los Angeles Abrasion loss of 27%. Rock 3 specifies Coarse Aggregate No. 1 Limestone sized 1.5" x 3" with gradation from 4" down to 3/4" sieves, specific gravity of 2.64 bulk dry, and 29% Los Angeles Abrasion loss. Rock 4 covers Sand/Clay/Gravel Aggregation (Pit Run) with a minimum of 30% metal content and aggregate size requirements, plus specifications for fine particles that must quickly form a hard, water-shedding road surface. Rock 5 defines Fill Dirt as 60/40 Clay/Sand/Dirt with a Plasticity of 19. Rock 6 specifies #2 Washed Gravel with size range of 1 to 2 inches and defined gradation percentages per ASTM C33 standards.
The specifications document does not contain information regarding pricing terms, set asides, contract term, renewal options, funding sources, or award dates. All materials are referenced to applicable ASTM and AASHTO testing standards to ensure quality and consistency. The document indicates that quality assessments for Rock 4 will be determined by LDWF personnel through visual inspection and water application testing to verify proper road surface formation and rutting resistance.

Rock 4 Specification Gradation For Sand/Clay/Gravel Aggregation (Pit Run)
Metal Content: 30% minimum with ¼” minimum aggregate size. Aggregates below ¼” in diameter will not count toward total metal.
Fine Particles: Considered as all sand, clay, other soil types, and aggregates below 1/4” shall be of a nature and property that sets up quickly after being spread to form a hard, water-shedding road surface that is not slick. In addition, the material must remain firm and exhibit minimal tendency to for ruts after normal rainfall events. This quality to be determined by LDWF personnel by visual inspection and/or application of water to a freshly spread material.
Rock 5 Fill Dirt Defined as: 60/40 Clay/Sand/Dirt with Plasticity of 19
Rock 6 #2 Washed Gravel Specifications
· Size Range: Generally 1 ½ to 2 ½ inches (ASTM C33).
· Gradation (ASTM C33): 90%-100% passing 2½-inch, 35%-70% passing 2-inch, 0%-15% passing 1½-inch, 0%-5% passing 3/4-inch.
