SECTION 515: REINFORCED CONCRETE FOR MINOR STRUCTURES
515.1 Description
This Work consists of providing reinforced concrete for minor S tructures.
515.2 Materials
The Contractor shall provide Class A concrete with a design com pressive strength of at least 3,000 psi in accordance wi th Section 510, “Portland Cemen t Concrete.” The Contractor shall provide Grade 40 or 60 reinforcing steel i n accordance with Section 540, “Steel Reinforcement.” The Department will allow field bending and cutting.
