Abstract:One of the primary objectives of this project was to develop a suitable method of fabricating specimens and determining laboratory compaction characteristics of granular materials. The need for this study became apparent from the results of two other projects conducted by the Texas Transportation Institute. Phase Three of Project 2-8-62-32, "Application of the AASHO Road Test Results to Texas Conditions", was a field sampling and testing study. It was the intent of this study to compact the materials in the laboratory at. their in-situ moisture contents, densities, and gradations and then determine the strengths of the remolded specimens. But in many cases the Texas Highway Department District Laboratories found it impossible to reproduce these conditions on granular materials using the standard Texas Highway Department Laboratory compaction method.
