Anotácia textu normy ASTM C1577-20e1 :
This specification covers single-cell precast reinforced concrete box sections cast monolithically and intended to be used for the construction of culverts and for the conveyance of storm water, industrial wastes and sewage. The reinforced concrete shall consist of cementitious materials, mineral aggregates and water, in which steel has been embedded in such a manner that the steel and concrete act together. The precast reinforced concrete box sections shall be produced with tongue and groove ends. The box section shall be cured using any of the following methods or combinations thereof: steam curing; water curing; and membrane curing. Compression tests for determining concrete compressive strength shall be allowed to be made on either standard rodded concrete cylinders or concrete cylinders compacted and cured in like manner as the box sections, or on cores drilled from the box section.

1.1?This specification covers single-cell precast reinforced concrete box sections cast monolithically and intended to be used for the construction of culverts and for the conveyance of storm water, industrial wastes and sewage. Note 1:?This specification is primarily a manufacturing and
purchasing specification. However, standard designs per the AASHTO
LRFD Bridge Design Specifications are included and the criteria
used to develop these designs are given in Appendix X1. The successful performance
of this product depends upon the proper selection of the box
section, bedding, backfill, and care that the installation conforms
to the construction specifications. The purchaser of the precast
reinforced concrete box sections specified herein is cautioned that
proper correlation of the loading conditions and the field
requirements with the box section specified, and provision for
inspection at the construction site, are required.
1.2?The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.3?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
