Innovative Concrete Bridging Systems for Pedestrian Bridges: Implementation and Monitoring

The use of High-Strength Concrete (HSC) has become ordinary in the transportation industry because of its beneficial economical and material properties. HSC is advantageous since it reduces material requirements, permits longer girder spans and allows for increased girder spacing; thereby reducing material and total bridge cost. Over the past few years, Self-Consolidating Concrete (SCC) has gained increased use and acceptance in the US due to the reduced potential for segregation, voids and surface defects. SCC can eliminate the need for vibration due to the availability of new admixtures, and therefore reduces fabrication time and labor costs. Due to these advantages, SCC is becoming the material of choice for the precast industry as numerous research studies in recent years have studied the material and mechanical properties of SCC for use in precast members. The combination of the performance characteristics of SCC with the engineering properties of HSC will produce a cost effective material for the construction industry. This study involves the construction and monitoring of two pedestrian bridges in the City of Rolla, Missouri. The research effort involves the implementation of High Strength-Self-Consolidating Concrete (HS-SCC) as an integrated precast system for pedestrian bridges.
