    Abstract

    This paper will illustrate the evolution of box culvert joints and sealing. Not every box culvert project contains the identical level of watertight requirements; some box culverts are exposed on each end of the water transportation through the section. For this type of application, butyl sealant has been used. These units must be sealed, but hydrostatic watertightness is not crucial. Certain box culverts need to be regulated for erosion over the joint. For erosion control applications, an exterior joint wrap and butyl sealant have been utilized. On the other hand, several box culverts are used as water containment structures. Presently, the issue has been to assess the precast box culvert system. Over the years, the precast box culvert specification has been revised or changed completely; due to the watertight system requirements, ASTM C1677, Standard Specification for Joints for Concrete Box, Using Rubber Gaskets, has established. This specification incorporates flexible joints for the concrete box section and the application of rubber gaskets for leak-resistant joints.
