Stripping test of aggregate

WebNov 25, 2016 · Anti-stripping agents are chemical mixtures containing active functional groups that improve the adhesion of the bitumen film on the surface of the aggregates. Mixed with the binder, they lower the surface tension of the bitumen (figures 2 and 3). There are different types of anti-stripping (amino, polyphosphoric or silane). WebThe materials, aggregate gradation, asphalt content, and compaction method adopted by the test were the same as the splitting test in the previous section. Specimens that had been fabricated were divided into three groups according to the air voids. It should be clear that the air voids of every group specimens are distributed uniformly.
