WebJan 1, 2015 · 2.2.2 Rolling Bottle Test EN 12697-11 (CEN 2012b) was used to evaluate the affinity between bitumen and aggregates on loose mix. According to the standard procedure, three bottles per each stone material, filled with 150 g of aggregates coated with bitumen and distilled water, were placed in the bottle rolling machine. Rolling bottle test results are shown as a percentage of bitumen coating. Figures 7 and 8show decreasing values for limestone and sandstone in which aged binder coating is increased for 6 h of rolling. For 24 h, 48 h and 72 h the value of bitumen coating is following the same trend of lower coating of a binder … See more In this approach to study the effect of aging on bitumen, conventional testing was performed.
