• Abstract:
  Lightweight concrete has been used successfully for the construction of bridges since soon after commercial production of lightweight aggregate began in the United States in 1920. Design provisions for lightweight concrete have been provided in AASHTO specifications for over 35 years. However, the material is not commonly used for bridge construction. This document presents basic information about lightweight concrete to equip owners, designers, specifiers, and contractors to design and evaluate the potential benefits, using the provisions of the AASHTO LRFD Bridge Design Specifications, 8th Edition, 2017, which are incorporated by reference at 23 CFR 625.4(d)(1)(v). Information presented includes laboratory data, field experience, and project descriptions which demonstrate that lightweight concrete can be used as a durable and cost-effective material for bridges.
