Method for evaluating aggregate-asphalt stickiness by virtue of mass loss rate

The invention discloses a method for evaluating aggregate-asphalt stickiness by virtue of a mass loss rate. The method comprises the following steps: preparing asphalt for a test and a coarse aggregate sample meeting requirements; firmly fastening the clean and dry coarse aggregate by using a fixing wire, suspending the coarse aggregate at the edge of a self-made weighing support top tray, and weighing by using an electronic scale; heating the aggregate, and then immersing the heated aggregate in preheated asphalt; after an asphalt film on the surface of the aggregate is cured, re-suspending the aggregate at the support, cooling, and weighing; collectively heating the support and the aggregate in hot water for a certain time, then heating and drying, cooling, and weighing; and evaluating the stickiness of the asphalt and the aggregate by adopting the mass loss rate. By adopting the method for evaluating the aggregate-asphalt stickiness by virtue of the mass loss rate, the defects of a water boiling method for
