Embodiment Construction
[0026] Introduce the embodiment of the present invention in detail below, and its test method is as follows:
[0027] 1. Preparation of instruments and materials
[0028] ⑴ Penetration effect tester of emulsified asphalt
[0029] Such as figure 1 As shown, the penetrating effect tester of emulsified asphalt is composed of machine base 1, vertical plate 2, movable support plate 3, 50ml bottomless glass measuring cylinder 4, funnel bracket 5 and funnel 6;
[0030] On the upper end of the machine base 1, the vertical plate 2 is fixed with screws and washers, and the vertical surface of the vertical plate 2 is flush with the end of the machine base 1 and constitutes vertical. The 50ml bottomless glass measuring cylinder 4 is installed on the side of the vertical plate 2. The measuring cylinder 4 is fixed in the groove of the measuring cylinder guide seat by the plastic pressure plate and the disc nut through the stud bolts. The bottom of the measuring cylinder 4 should be close ...

Abstract
The invention discloses a method for testing a permeation effect of prime coat emulsified asphalt. The method is executed by a prime coat emulsified asphalt permeation effect tester and comprises the steps of adding 50 grams of homogenized standard sand into a 50-millimeter bottom-free glass measuring cylinder of the tester, diluting the standard sand by adding water, adjusting the standard sand into 45 percent emulsified asphalt, adding 7 grams of the emulsified asphalt into the measuring cylinder for permeation for 10 minutes, opening a movable carrying plate at the bottom of the bottom-free measuring cylinder of the tester to enable the non-adhered homogenized standard sand to fall off, weighing the mass of the non-adhered homogenized standard sand, calculating the volume of the homogenized standard sand permeating into the emulsified asphalt, and calculating and estimating the permeation speed of the emulsified asphalt. Prime coat emulsified asphalt products with different permeation capacities can be effectively distinguished, so that whether the products can be used for highway semirigid base-layer prime coat construction can be evaluated. The method is easy to operate, accurate in metering and credible in result; the outstanding technical difficulties that the prime coat emulsified asphalt home and abroad at present cannot be subjected to qualitative and quantitative permeation index test in actual engineering application are effectively solved; and the method for testing the permeation effect of the prime coat emulsified asphalt has popularization and application value.
Description
technical field [0001] The invention relates to a method for testing the technical performance of emulsified asphalt, in particular to a method for testing the penetrating effect of emulsified asphalt in a permeable layer. Background technique [0002] Abroad, there are few index requirements and testing methods for testing the permeability of emulsified asphalt in permeable layers. Only the test method of emulsified asphalt for penetrating layers such as Japan, Japan Emulsified Asphalt Association Standard (JEAAS) permeable test method for high-permeable emulsified asphalt uses Marshall testing machine, uses compacted standard sand to make test pieces, and sprays quantitative emulsified asphalt Spray on the test piece to check its permeability. The disadvantage of this detection method is that the penetration quality is mainly judged by the observation of the operator. Since the penetration effect of the emulsified asphalt of the permeable layer is not obvious, the human i...
