PLANT STABILITY TEST FOR HOT-MIX ASPHALTIC CONCRETE MIXTURES

A NEW METHOD OF TESTING THE CONTROL OF ASPHALTIC CONCRETE MIXTURES AT HOT-MIX PLANTS IS SUGGESTED. THE UNIQUE FEATURE OF THIS TEST IS THE RAPIDITY OF ITS OPERATION. TIME FROM THE MOLDING OF THE SPECIMEN TO THE END OF TESTING IS ABOUT TEN MINUTES. A SINGLE MOLD HAS BEEN DEVELOPED FOR BOTH MOLDING AND TESTING WHICH ELIMINATES THE NEED FOR EXTRUDING THE SPECIMEN. IN ADDITION, AN ARMORED THERMOMETER IS USED TO MEASURE THE TEMPERATURE OF A SPECIMEN BEFORE TESTING. IT IS NECESSARY, THEREFORE, TO KEEP A SPECIMEN IN A HOT WATER BATH OR CONSTANT TEMPERATURE OVEN FOR A CERTAIN PERIOD AS REQUIRED IN ORDINARY STABILITY TESTS. /AUTHOR/
