Abstract:

In an effort to find a solution to the shortage of aggregate, for use in highway construction, Louisiana Department of Highways initiated a study.

In early 1955, we started experimenting with expanded aggregate or lightweight aggregate as commonly referred to in Louisiana. Our first objective was to develop a satisfactory hot mixture. The preliminary tests indicated that a very good mixture can be produced and that it would, possess abnormally high stability in spite of a high flow. The increase in the stabilities were attributed to the angularity of the particles and the extremely rough surface texture.
