This Standard deals with both large (structural) and small (non-structural or light structural) box culverts of rectangular cross-section formed monolithically and designed as continuous elements with a joint detail shaped to allow the possible incorporation of sealing materials. Box culverts may be used for creation of voids below ground for conveyance and storage. For the purposes of this Standard, box culverts having internal cross-sectional dimensions (B and D in Figure 1) less than or equal to 1 250 shall be considered as small and non-structural. All other units shall be defined as large. The elements are generally manufactured in factories using either normal weight or lightweight concrete and usually require passive reinforcing steel. They may be produced either by wet cast or dry cast methods. This Standard does not include units manufactured from autoclaved aerated concrete. Each unit is structurally complete. They are used in combination to form a total structure of appropriate length (including joints) and capacity. This Standard identifies the basic performance criteria and specifies minimum values where appropriate to meet the Essential Requirements of the Construction Products Directive (89/106/EEC).
