Specifies requirements for the design, testing, manufacture and installation of precast reinforced concrete rectangular box culverts, for conveying water not under pressure and for carrying roadway and railway loadings.
This Standard sets out minimum requirements for the design, testing, manufacture and installation of precast reinforced concrete rectangular box culverts for conveying water not under pressure, and for carrying roadway and railway loadings permitted by Australian road and railway authorities.
Design requirements are based on the methods of limit state design, using theoretical strength and serviceability calculations, or prototype testing.
This Standard is applicable to rectangular precast culvert units having a maximum length of 3600 mm, a maximum height of 4200 mm and a span from 1500 mm to 4200 mm and having a height of fill over the top of the culvert unit not exceeding 10 m.
1 Guidelines to purchasers on requirements that may need to be agreed upon at the time of calling for tenders or quotations are detailed in Appendix A.
2 Methods for demonstrating compliance with this Standard are given in Appendix B.
3 For precast reinforced box culverts of internal dimensions exceeding 4200 mm span or height, additional design considerations may be necessary. Additional design considerations are required for special culverts, e.g. skewed ends, culvert units with large holes, culverts subject to loading other than standard roadways and railways loadings.
All large precast reinforced concrete rectangular box culverts designed, manufactured, tested and installed in accordance with this Standard shall comply with the relevant requirements of Sections 1 to 6, with the alternative requirements as applicable.
