ACCELERATED SOUNDNESS TEST FOR AGGREGATE

THE OBJECTIVE OF THIS STUDY HAS BEEN TO COMPARE THE PRESENT STANDARD TESTS AS WELL AS THE ACCELERATED SOUNDNESS TESTS WITH OBSERVED FIELD PERFORMANCE OF VARIOUS TYPES OF ROCKS IN ORDER TO FIND A TEST WHICH WILL MORE ACCURATELY REFLECT THE DURABILITY OF THE ROCKS. THE ACCELERATED SOUNDESS TESTS CONSIST OF SUBMERGING THE ROCK SAMPLES IN SOLUTIONS OF ETHYLENE GLYCOL, POTASSIUM ACETATE, AMMONIUM ACETATE, AND DIMETHYL SULFOXIDE FOR PERIODS OF 15 DAYS. AT THE END OF THE 15 DAY TEST CYCLE, THE PERCENT WEIGHT LOSS ON EACH SAMPLE IS DETERMINED AND COMPARED ALONG WITH SODIUM SOUNDNESS TEST RESULTS, ABRASION TEST RESULTS, AND ABSORPTION TEST RESULTS TO THE DURABILITY OF THE ROCKS DETERMINED BY FIELD OBSERVATIONS. RESULTS OF THIS COMPARISON INDICATE THAT NO SINGLE TEST WAS SATISFACTORY FOR PREDICTING THE PERFORMANCE OF ALL ROCK TYPES. INSTEAD, DIFFERENT TESTS APPEAR TO BE MORE SUITABLE FOR EVALUATING DIFFERENT TYPES OF ROCKS. THE ABRASION OF COARSE AGGREGATE TEST SHOWED THE BEST CORRELATION WITH OBSERVED FIELD PERFORMANCE OF METAMORPHIC ROCKS. THE ABRASION TEST AND THE SODIUM SULFATE SOUNDNESS TEST CORRELATED WELL WITH THE FIELD PERFORMANCE FOR SEDIMENTARY ROCKS. THE ABSORPTION TEST SHOWED THE BEST CORRELATION FOR IGNEOUS ROCKS.
