AASHTO M 259M-17涵盖了单室预制钢筋混凝土箱形截面，拟用于涵洞施工和雨水、工业废物和污水输送。本规范为M 259的公制对应规范。本规范主要是制造和采购规范。然而，标准设计也包括在内，附录中给出了用于开发这些设计的标准。本产品的成功性能取决于箱形截面、垫层和回填的正确选择，并注意安装符合施工规范。 此处规定的预制钢筋混凝土箱形截面的业主应注意，荷载条件和现场要求必须与规定的箱形截面适当相关，并且必须在施工现场进行检查。对于小于27m的公路段，采用AASHTO进行装载。如果需要荷载和阻力系数设计（LRFD），则使用ASTM C 1577。

AASHTO M 259M-17 covers single-cell precast reinforced concrete box sections intended to be used for the construction of culverts and for the conveyance of storm water, industrial wastes, and sewage.This specification is the metric counterpart of M 259.This specification is primarily a manufacturing and purchasing specification. However, standard designs are included and the criteria used to develop these designs are given in the Appendices. The successful performance of this product depends upon the proper selection of the box section, bedding, and backfill, and care that the installation conforms to the construction specifications. The owner of the precast reinforced concrete box sections specified herein is cautioned that the loading conditions and field requirements must properly correlate with the box section specified and that inspection at the construction site must be provided.AASHTO M 273M is to be used for box sections with less than 0.6 m of cover subjected to highway loading.If load-and-resistance factor design (LRFD) is required, then use ASTM C 1577.
