Use of All Lightweight Concrete in Conjunction with UHPC Connection for Prefabricated Barrier System

The use of all lightweight concrete in barriers and in some cases bridge overhangs provides a reduction in the total weight of the barriers by almost 33% allowing the transportation of more barrier units on one truck and easy handling. Furthermore, in seismic regions, lighter barrier contributes to a lesser total mass of bridge superstructures which is beneficial in many cases. In this project, two barriers, made of all lightweight concrete, will be tested under static load test setup and the results will be compared to the specimens which are being tested under project number [ABC-UTC-2016-C3-FIU05].
