HPC and Innovative Design Ensure Long-Term Durability

This paper describes how experience has shown that bridges with continuous beams and rigid frame abutments exhibit better long-term durability than bridges with leakage-prone roadway joints. Thus, when the existing Great Road Bridge (State Route 119) over the Boston & Maine Railroad in Littleton, MA, required replacement, every attempt was made to eliminate these joints. Building a cast-in-place structure was not feasible since the falsework would reduce the existing railroad clearances. The Massachusetts Highway Department (MassHighway) decided to use “emulation design” to replicate cast-in-place concrete construction with precast, prestressed concrete beams and precast concrete abutment panels.
