In joints of precast concrete bridge segments, what are the functions of applying epoxy adhesive?

In joints of precast concrete bridge segments, what are the functions of applying epoxy adhesive?
by

1 Answer

Answer :

Epoxy adhesive is applied in these joints for the following purposes according to
International Road Federation (1977):
(i) It seals up the joints completely between precast concrete segments to protect the prestressing tendons;
(ii) By filling voids and irregularities along the segment joints, it helps to reduce stress concentrations otherwise it will be developed; and
(iii) It helps in transferring of shear between the joints in case a large single shear key is used.
