A PROGRESS REPORT ON STUDIES OF DEGRADING BASALT AGGREGATE BASES
A BRIEF HISTORY IS PRESENTED OF AGGREGATE DEGRADATION IN IDAHO, INCLUDING REFERENCE TO PROJECTS THAT HAVE FAILED IN SERVICE. A LABORATORY TEST METHOD WHICH HAS BEEN DEVELOPED TO ANTICIPATE DEGRADATION TENDENCIES IN BASE AND SURFACING AGGREGATES IS DISCUSSED. IN ADDITION, A METHOD IS DESCRIBED WHEREBY PETROGRAPHIC EXAMINATION OF PRELIMINARY SAMPLE IS USED TO DETERMINE THE QUALITY OF A MONTMORILLONITE MINERAL WHICH IS ASSOCIATED WITH DEGRADATION. AN ATTEMPT IS MADE TO CORRELATE THE RESULTS OF THE LABORATORY TEST AND PETROGRAPHIC EXAMINATION TO ESTABLISH MINIMUM STANDARDS FOR ACCEPTANCE OF AGGREGATES. /AUTHOR/
