Bitumen affinity test
WebMay 7, 2015 · Affinity between bitumen and coarse crumb rubber, with particle sizes comprised between 1 and 4 mm, was evaluated by subjecting mortars of known composition to the volumetric expansion test (VET). Measured volumetric behavior was compared to that of reference blends prepared with the same base bitumen and inert silica sand. WebIn the static test method, the affinity is expressed by visual registration of the degree of bitumen coverage on uncompacted bitumen-coated mineral aggregate particles after storage in water. NOTE 2 The static test is a simple, though subjective test that is generally less precise, but that can cope with high PSV-aggregates.
