Accelerated Construction of Bridge 14802301, Greene County, Missouri, with Prefabricated Stay-in-Place Glass Fiber Reinforced Polymer Reinforcement; Final rept

摘要

In the two-year project reported herein, a new prefabricated stay-in-place (SIP) glass fiber reinforced polymer (GFRP) reinforcing system for the accelerated construction of bridge decks was developed and implemented in the reconstruction of Bridge 1482301 in Greene County, Missouri, USA. The owner opted for the replacement of the 70-year old bridge due to the severe corrosion-induced deterioration of the superstructure. A significant joint effort was required for the concept development, design, analysis, detailing, full-scale laboratory validation, development of project special provisions, and construction planning and execution. Related tasks were completed in coordination between Missouri S&T and the University of Wisconsin-Madison, FRP reinforcement manufacturers, the Greene County Highway Department (owner), the engineer-of-record, and the designated contractor. The project demonstrated a technology that combines the superior durability of internal FRP reinforcement for concrete, and the substantial constructability advantages that derive from the use of light-weight advanced composite systems engineered in an innovative, integrated stay-in-place form.
