1.1 This specification covers precast reinforced concrete box sections comprised of separate segments that once properly field assembled make the final structure. These structures are 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, box culverts manufactured to this standard are intended to meet the design requirements of the AASHTO LRFD Bridge Design Specifications, and as such, design guidance is included in Appendix X1.

Note 2: 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 standardizati
