Novel Railway Bridge Strengthening System
The system involves injecting polymer into railway ballast to create a strong, stiff raft which reduces the stresses experienced by an underlying masonry arch bridge. It is designed to provide a rapid and cost-effective alternative to conventional strengthening systems (e.g. those involving saddling, under-ringing or reinforcing the arch barrel using metallic elements).
Further details are provided in a recent Engineering News Record article.
