Abstract
The invention discloses a device and a method for measuring the permeability of an asphalt recycling agent. The device comprises a heating box, a support frame, N test tubes, N dropping needles, N fixing clamps, a measurement controller, a heating wire, a temperature controller for controlling temperature in the heating box, and N displacement sensors for detecting the dropping displacements of the dropping needles; the support frame comprises a first cross rod and a second cross rod; the measurement controller comprises a controller, a power switch, a dropping needle depth display screen, a dropping needle depth display screen adjustment button, and a dropping needle starting button for controlling the opening and closing of the fixing clamps; the output end of each displacement sensor is connected with the input end of the controller; the output end of the controller is connected with the dropping needle depth display screen; the dropping needle depth display screen adjustment button is connected with the control end of the controller. According to the device and the method, provided by the invention, the measurement of the permeability of the asphalt recycling agent can be realized.
Description
technical field [0001] The invention belongs to the field of road engineering and relates to a measuring device and method, in particular to a measuring device and method for the permeability of asphalt regenerant. Background technique [0002] As most of the roads in our country enter the stage of major and medium repair, a large amount of waste asphalt mixture will be generated during asphalt pavement renovation. Reasonable disposal of these mixtures can not only achieve good economic benefits but also save resources. However, the waste asphalt mixture cannot be used directly, and an asphalt regenerant is needed to change its performance, so that the reused asphalt mixture can show excellent pavement performance. The permeability of regenerated agent in asphalt mixture is a key index to evaluate the quality of regenerated agent, but currently there is a lack of measuring devices and methods for the permeability of asphalt regenerated agent.
