STUDY OF CURRENTLY USED METHODS FOR DETERMINING THE PERMEABILITY OF BITUMINOUS MIXTURES

FIFTEEN PERMEAMETERS ARE REVIEWED ALONG WITH A STUDY ON THE ADVANTAGES, DISADVANTAGES, AND LIMITATIONS OF THE SIX MOST CURRENTLY USED METHODS. THE REVIEW SHOWS THE NEED FOR SELECTING THE TYPE OF PERMAMETER ACCORDING TO THE PURPOSE OF MEASUREMENTS TAKING INTO ACCOUNT THEIR INHERENT LIMITATIONS. IT ALSO SHOWS THE NEED FOR ESTABLISHING A STANDARD PERMEABILITY UNIT. TESTS WERE MADE ON LABORATORY MOLDED SPECIMENS, ON SLAB SURFACES, AND ON CORES EXTRACTED FROM SLABS. FOR BITUMINOUS MIXES CONTAINING MORE THAN SIX PERCENT VOIDS, THERE IS A GOOD CORRELATION BETWEEN PERMEABILITY AND VOIDS, FIELD AND LABORATORY TESTS, AIR PERMEAMETERS AND WATER PERMEAMETERS, AND PERMEABILITY AND RATE OF FLOW. /AUTHOR/
