DOT & Government Specification Aggregate
DOT and Government Specification Aggregate Sourcing
Government and public-works projects rarely call for "gravel." They call for a designation written by a state DOT or an agency specification. Gravel USA sources against that written requirement through quarries near the project and coordinates delivery through independent, insured carriers.
The Same Material, Ten Different Names
Dense-graded aggregate base is written differently in nearly every jurisdiction. These are common designations we are asked to source. Requirements are set by the specifying agency, not by us — send the spec and we will confirm what local quarries can supply against it.
Mid-Atlantic
- VDOT 21A and 21B (Virginia)
- Maryland CR-6 and crusher run
- PennDOT 2A subbase
- Delaware and DC agency designations
Southeast
- NCDOT ABC aggregate base course
- SCDOT graded aggregate base
- Georgia and Florida base designations
- Riprap classes by agency
West & Southwest
- Caltrans Class 2 aggregate base
- TxDOT flexible base, Item 247
- Arizona ABC and select material
- Regional decomposed granite
What We Can and Cannot Provide
Where a project requires gradation reports, quarry certifications or source approval documentation, we request it from the supplying quarry and pass it through with the material. Availability depends on the quarry and the agency — we confirm in writing what is obtainable for your specific source before you commit, rather than promising paperwork we do not control.
Gravel USA is a managed aggregate supplier and delivery coordinator. We are not a quarry, a testing laboratory or a motor carrier. We do not hold DOT source approval ourselves; the approved source is the quarry, and we coordinate the purchase and delivery from it.
Pricing for Bids and Awarded Work
Bid-Stage Pricing
Send the solicitation, plan sheet or material schedule and your bid deadline. We return delivered pricing with the assumptions written out so it can go straight into your estimate.
Awarded Projects
For active work we coordinate scheduled deliveries, arrival communication, scale tickets and delivery documentation through one point of contact instead of a separate quarry and hauler for every load.
Have a Specification or Solicitation to Price?
Send the material designation, project location, estimated tonnage and delivery window. We will review sourcing and coordinated-delivery options against the written requirement.
