MARSHALL-IMMERSION TEST STUDY

THIS REPORT CONTAINS THE RESULTS OF A STUDY TO MEASURE THE EFFECT OF WATER IMMERSION ON THE STABILITY OF LABORATORY MOLDED MARSHALL SPECIMENS IN COMPARISON WITH THE LOSS OF STRENGTH AS MEASURED BY THE IMMERSION-COMPRESSION TEST, AND TO ESTABLISH A CRITERION FOR THE MINIMUM VALUE OF THE INDEX OF RETAINED STABILITY. GRANULAR AGGREGATES FROM TWO AREAS WERE USED IN A MIXTURE OF WEARING COURSE GRADATION WITH 5.0 PER CENT AND 5.5 PER CENT ASPHALT CONTENT AND IN A MIXTURE OF BINDER COURSE GRADATION WITH 4.0 PER CENT AND 4.5 PER CENT ASPHALT CONTENT. SIX PERCENT MINERAL FILLER WAS USED IN EACH MIXTURE, THE FILLER BEING COMPOSED OF DIFFERENT COMBINATIONS OF HYDROPHOBIC /LIMESTONE/ AND HYDROPHILIC /ANHYDRITE/ MINERALS. IT WAS CONCLUDED THAT A CORRELATION EXISTS BETWEEN THE TWO TESTS, AND THAT A GRAPH CAN BE USED TO ESTIMATE THIS CORRELATION. IT WAS FURTHER CONCLUDED THAT THE TYPE OF THE AGGREGATE AND THE QUANTITY OF THE ASPHALT CEMENT HAVE AN INFLUENCE ON THE RESULTS, BUT THAT FURTHER TESTING IS NECESSARY BEFORE THE EXTENT OF THIS INFLUENCE CAN BE ASCERTAINED. /AUTHOR/
