Background

The emulsified asphalt mixture is widely used in the field of road engineering, such as micro-surfacing, cold recycling and the like, and with the improvement of the emulsified asphalt technology, the application range of the emulsified asphalt mixture in a pavement structure layer is continuously expanded. The gradation of the mixture is an important factor influencing the quality stability of the mixture, which requires technical personnel to carry out gradation inspection on the mixture produced actually, but the gradation inspection of the emulsified asphalt mixture has the following problems:

firstly, the hot-mix mixture is specified in detail in the country at present, but the grading inspection method for the emulsified mixture is unclear, for example, the micro-surfacing asphalt mixture is inspected through the consumption of each grade after large-area construction is adopted at present, and the mixture is often premixed during large-scale construction actually, so that the method is extremely rough and inaccurate;

secondly, materials such as cement and lime are often required to be added into the emulsified asphalt mixture for production, for example, the addition amount of the cement in the mixture such as micro-surfacing is 0-3%, the hydration and other actions of cementing materials such as cement and lime enable the materials such as cement to be coagulated into small particles (which can be dispersed) or attached to the surface of aggregate, and a lot of testers directly perform screening tests without treatment or perform common water washing methods, so that the cleaning is time-consuming and has poor effect.

And thirdly, cement and lime are used as additives, the functions of the additives are different from the functions of mineral powder and other fillers, and the most part of the lime and the cement is added into mineral powder and other aggregates by the conventional grading method due to the fact that the particle size of the lime and the cement is 0.075 mm.

The operation mode directly causes serious deviation of the test result from the actual situation, and can not guide production. In the prior art, a grading screening verification method for emulsified asphalt mixtures containing cementing materials such as cement and lime is basically in a blank state.
