Abstract

The invention discloses a device and a method for measuring the expansion ratio of experimental foamed asphalt. The device comprises a motor, a stirring device, a cylinder body, a cylinder cover and an angular contact ball bearing, wherein the cylinder body is a cylinder body of which the upper end is opened; the cylinder cover is fixedly arranged on the opening in the top of the cylinder body; ahole is formed in the cylinder cover, the angular contact ball bearing is arranged in the hole, and the stirring device penetrates through the hole to be arranged in the cylinder body; the angular contact ball bearing is arranged on the stirring device; and the stirring device above the cylinder cover is connected with the motor. According to the device and the method disclosed by the invention, aconventional method for measuring the expansion ratio is improved. The method is simple, easy to operate and high in accuracy, is capable of changing experimental conditions according to different research contents of the foamed asphalt, and has significances on intensive study of the foamed asphalt.

Description

technical field [0001] The invention belongs to the technical field of road engineering, in particular to a device and method for measuring the expansion ratio of foamed asphalt used in experiments. Background technique [0002] Due to the advantages of low production temperature, low energy consumption, low emission, and little effect on asphalt aging, foamed asphalt mixture is more and more used in the field of road construction. The expansion ratio and half-life are important indicators for evaluating the foaming effect of foamed asphalt. The expansion ratio refers to the ratio of the maximum volume reached when the asphalt expands to the volume when the foam completely disappears. Because foamed asphalt foam bursts relatively quickly, generally within a few seconds or more than ten seconds, the foam will completely disappear, so it is difficult to measure the expansion ratio. [0003] At present, the measurement of the expansion ratio adopts the observation method or th...
