Abstract:

Two case studies are presented of the use of precast polymer concrete stay-in-place forms for rehabilitation of transportation structures. The first study is on precast median barrier shells used by the Pennsylvania Turnpike Commission. The new barrier replaced an obsolete, deteriorated 4-ft-wide concrete island. The shells are 1-in.-thick and come in 20-ft-long sections. They are placed on the roadway, aligned, anchored with anchor bolts, then filled with conventional concrete through holes at the top of each section. The system is easily and rapidly installed, and provides a more impact-resistant and durable barrier than conventional concrete barriers. The second study is on precast bench panels that replaced deteriorated bench walls in Boston's Sumner Tunnel. Polymer concrete panels were selected because of their high strength and high modulus, good impact resistance, and their outstanding resistance to de-icing salts, chemicals, and freeze-thaw. The work, performed during the night, consisted of placing and anchoring panels, sealing off vent openings to prevent backfill concrete from coming out, then placing concrete behind the panels. In addition to improved performance properties, rapid construction time was a major benefit.
