THE PROPERTIES OF ROAD TAR - THE EFFECT OF EXPOSURE

WHILE EVAPORATION IS GENERALLY ACCEPTED AS THE MAJOR FACTOR IN DETERMINING THE CHANGES THAT OCCUR IN ROAD TARS ON EXPOSURE, OTHER INFLUENCES SUCH AS POLYMERIZATION AND OXIDATION MAY HAVE IMPORTANT SECONDARY EFFECTS WHICH MAY AFFECT THE INTERPRETATION OF THE RESULTS OF LABORATORY EXPOSURES IN TERMS OF PRACTICAL UTILITY. IN THE PAPER, THE AUTHORS STUDY THE BEHAVIOR OF ROAD TARS UNDER SIMPLE BUT CAREFULLY CONTROLLED CONDITIONS TO DETERMINE THE EFFECT OF (1) EVAPORATION, (2) OXIDATION, (3) LIGHT, (4) MOISTURE, (5) PRESENCE OF AGGREGATE, (6) DETRITUS, (7) THIXOTROPY, AND (8) TRAFFIC AND THE INFORMATION OBTAINED IS APPLIED TO MORE COMPLEX CONDITIONS SUCH AS MAY OCCUR WHEN TAR IS USED IN ACTUAL ROAD CONDITIONS.
