The Virginia Transportation Research Council has released a new report which is favorable for using lightweight aggregate in overlays and closure joints on bridges. It shows that using lightweight aggregate, either coarse or fine, is a recommended option to reduce cracking for overlays.
The NCHRP Report 733 on high-performance high-strength lightweight concrete for bridge girders and decks.
This educational article was written by structural engineers and compares the performance of LWC and NWC on suspended steel deck floors. The article goes beyond moisture issues and includes cost and benefit comparisons with an unbiased approach.
This research report covers the study performed by ESCSI in Dalton, Georgia and the controlled environment study done with WR Grace in 2009.

This report presents the results of an embodied energy study performed by Walter P. Moore and Associates, Inc. The purpose of the study was to compare the embodied energy in the structural system of a steel framed building with lightweight concrete floor slabs on composite steel deck to the same system utilizing normalweight concrete.
This report presents the results of the cracking tendency of lightweight concrete performed by the Highway Research Center at Auburn University’s College of Engineering.
