• Abstract:
  Pavement stripping due to loss in adhesion/binding between asphalt binder and aggregate in presence of moisture is a common and challenging pavement distress in wet climates such as Vermont. Although Vermont Agency of Transportation (VTrans) requires Hamburg Wheel Tracking Test (AASHTO T 324) during mix design approval, MRD-10 is required daily if the source aggregate is known to be prone to stripping. MRD-10 test is usually conducted on aggregates retained on US No. 4 Sieve, excluding fine aggregates present in the asphalt concrete making this test unreliable. Thus, in this study, the effectiveness of ASTM D3625 (i.e. boiling water test), a more common test in other state DOTs is evaluated.
