Application

Precast concrete box sections are designed to meet job specific requirements and are manufactured under factory controlled conditions employing the latest in dry cast manufacturing technology. They may be used for the construction of culverts, retention tanks, vertical vaults, utility corridors and for the conveyance of storm water, industrial waste and sanitary sewage. Precast concrete box sections are the logical solution to problems of restricted head room, minimum cover, limited trench width or excessive over fills, and can be designed for lacking under roads without traffic interruption.

Design

Designs are in accordance with ASTM C1433 using BOXCAR, an extension of the programs used for the development of AASHTO standards M259 and M273 which the ASTM standards are based on. Designs for HIS Series highway traffic loads, Cooper E Series railway loading, or other live loads may be accommodated upon request.

Connection

Precast reinforced concrete box sections are produced with bell and spigot ends. A butyl rubber based compound, such as Rub-r-Nek or Ram-nek, can be used on the joint but does not provide a waterproof joint. Water proofing compounds may
be applied by the Contractor in the field.
