The invention discloses an asphalt binder determining force-ductility test method which is an asphalt binder low-temperature test method and includes the following steps: step 1: taking an asphalt sample, heating up to the flow state, and casting the asphalt sample into a gap between the side mould (1) and the end mould (2) of a test mould to form a ring-like asphalt sample (3); step 2: cooling in the air, excising the part of the asphalt sample (3) which is higher than the test mould e; step 3: putting the asphalt sample in the water bath of a goal test temperature, taking down the side mould (1) of the sample, hitching holes on both ends of the test mould separately onto the metal columns of a slide plate (4) and a trough end fixed plate (5); step 4: setting parameters of the determining force-ductility test, reading the determining force-ductility curve. The invention provides the reasonable operation steps and the essential testing method of the test for proposing the index and establishing the standard of the low temperature asphalt.
