AASHTO M 259M-17 PDF Download

AASHTO M 259M-17 is a standard specification that describes the requirements for single-cell precast reinforced concrete box sections used in the construction of culverts, storm drains, and sewers. The specification specifically applies to the metric system of measurement.

The purpose of this specification is to provide guidelines for the manufacturing and purchasing of these box sections. It also includes standard designs and criteria for their development, which are provided in the Appendices. The successful performance of these box sections depends on the proper selection of the box section itself, as well as the proper bedding, backfill, and adherence to construction specifications during installation. The owner of the precast reinforced concrete box sections is reminded of the importance of ensuring the loading conditions and field requirements are appropriate for the specified box section, and that proper inspection is carried out at the construction site.

For box sections with less than 0.6m of cover subjected to highway loading, AASHTO M 273M is to be used as an alternative specification.

If load-and-resistance factor design (LRFD) is required, this specification refers to the use of ASTM C 1577.
