WebMar 7, 2024 · A rolling bottle test (RBT) was used to assess the adhesion and stripping properties of the binder-aggregate mixture and the test was performed following BS EN 12,697-11A [ 21 ]. RBT is a test in which residual bitumen coverage on the aggregate surface is determined by visual estimation for four cycles (6, 24, 48, and 72 h) of the test. WebFigure 1. Rolling bottle machine. 3. ROUND ROBIN TEST Seven laboratories participated in the round robin test on the Boiling Test and the Rolling Bottle Test (Jørgensen 2001). One sample of bitumen 160/220, one sample of “amine” (adhesion agent) and one sample of each of the four aggregates were distributed to the participating laboratories. lindsay city services
