ASTM International Standard Specification for Manufacture of Precast Reinforced Concrete Three-Sided Structures for Culverts and Storm Drains ASTM C1504-04(2010)

This specification covers single-cell precast conventionally reinforced concrete three-sided structures intended to be used for the construction of culverts and for the conveyance of storm water. Precast reinforced concrete three-sided structures manufactured shall be designated by span, rise, and design earth cover. The reinforced concrete shall consist of cement, fly ash, ground granulated blast-furnace slag, aggregates, admixtures and blends, steel reinforcements, and synthetic fibers. The aggregates shall be sized, graded, proportioned, and mixed with such proportions of cementitious materials and water as will produce a homogeneous concrete mixture. The concrete shall be subjected to either steam curing, water curing, or membrane curing. Compression tests for determining concrete compressive strength may be made on either standard rodded concrete cylinders or concrete cylinders compacted and cured in like manner as the structure compacted and cured in like manner as the three-sided section, or on cores drilled from the three-sided section.
