3、(June 2017) ASTM Designation: C789-95a 1. SCOPE 1.1. This specification 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. 1.2. A complete metric companion to M 259 has
4、 been developedM 259M; therefore, no metric equivalents are presented in this specification. Note 1This 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 Appendixes. The succ
5、essful performance of this product depends on 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 condition
6、s and the field requirements must properly correlate with the box section specified and that inspection at the construction site must be provided. Note 2M 273 is to be used for box sections with less than 2 ft of cover subjected to highway loading. Note 3If load-and-resistance factor design (LRFD) i
7、s required, then use ASTM C1577. 2. REFERENCED DOCUMENTS 2.1.
