Problems solved by technology
[0004] There are two defects in the current method of testing asphalt foaming characteristic parameters: 1. The error of the test is large and the accuracy is low. For this reason, multiple parallel tests are required to obtain relatively stable data; 2. The test can only measure the expansion The two indicators of rate and half-life have no record of the whole process of foam asphalt decay
Moreover, the existing test methods have low efficiency, low precision, low repetition rate, and are difficult to popularize and apply.

Abstract
The invention discloses a device for testing asphalt forming characteristics. The device comprises a measuring cylinder, a movable ruler, a flat plate device, a processor and a bracket and is characterized in that: the measuring cylinder is used for carrying asphalt; the movable ruler is connected with the processor which is connected with the bracket; the end of the movable ruler is provided with an object carrying device; and the flat plate device is placed on the object carrying device for fixing, and the flat plate device is contacted with the upper surface of asphalt. The invention also discloses a method for testing the asphalt forming characteristics. According to the device and the method for testing the asphalt forming characteristics, characteristic parameters such as expansion ratio, a half-life period and the like in an asphalt forming process can be automatically tested, and the asphalt forming characteristics can be tested comprehensively and conveniently.
Description
Technical field [0001] The invention belongs to the field of road engineering, and relates to an asphalt foaming characteristic testing device, in particular to a testing device that can automatically measure the expansion rate and half-life index in the asphalt foaming process. Background technique [0002] Asphalt pavement recycling refers to the recycling technology of old pavement materials, including hot recycling and cold recycling. Foamed asphalt cold recycling is an important part of asphalt pavement cold recycling technology. The foaming characteristics of asphalt are one of the key factors that affect the performance of foamed asphalt mixture and the success or failure of cold recycling engineering applications. The design of foamed asphalt cold recycled mixture must first conduct asphalt foaming test to obtain the foaming characteristic parameters of asphalt. At present, the expansion rate and half-life index are mainly used for the foaming characteristic parameters o...
