Determination of Transport Properties of Lightweight Aggregate Concrete for Service Life Modeling (Jan. 2017)

A new study recently conducted to determine the effects of expanded shale, clay and slate (ESCS) lightweight coarse and fine aggregates on the transport properties and other durability related properties of concrete show that the service life will be increased when using lightweight aggregate as compared to normalweight concrete. Article and Press Release.

Low Cracking Concretes for the Closure Pours and Overlays of the Dunlap Creek Bridge

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.
