[0007] The first test method requires related tests on the actual road surface. Although it can directly reflect the permeability of emulsified asphalt, it needs to be tested on the actual road surface. Some damage was caused; although the second test method can be carried out indoors, it is convenient and quick, but the influence of human factors in the test process is relatively large; the third test method is difficult to reach the actual road surface due to the limited height of the formed test piece. Compaction, the porosity of the formed test piece is larger than the actual road surface, and the test results are quite different from the actual ones
Therefore, the use of the above test methods to evaluate the permeability of emulsified asphalt has certain defects. It is necessary to develop an indoor quantitative evaluation of the penetration performance of emulsified asphalt. evaluation of

Embodiment Construction
[0025] Such as figure 1 As shown, the tester of the present invention includes a base 1 and a pole 2 vertically arranged on the base 1, and a permeable stone 3 (diameter 80mm, thickness 10mm) is placed on the base 1, and the middle part of the permeable stone 3 is opened There is a circular groove, and the step-shaped sleeve 4, which is small at the top and large at the bottom, is placed on the base 1 to cover the permeable stone 3, and a glass tube 5 (height 170mm, outer diameter 26mm, Inner diameter 23.5mm), the lower edge of the glass tube 5 is embedded in the circular groove of the permeable stone 3; a funnel 7 (caliber 90mm) is placed in the funnel fixing ring 6 horizontally arranged on the support rod 2, and the outlet of the funnel 7 The feed port corresponds to the center position of the glass tube 5; in order to adjust the height of the funnel, the funnel fixing ring 6 is movably arranged on the support rod 2 through the fastening bolt 8.

Abstract
The invention discloses a tester which comprises a base and a fulcrum bar vertically arranged on the base. A porous stone is placed on the base and wrapped in a sleeve which is buckled on the base, a glass tube is inserted in the sleeve, the lower edge of the glass tube is attached to the upper surface of the porous stone, a funnel is placed in a funnel fixing ring which is horizontally arranged on the fulcrum bar, and a discharging port of the funnel corresponds to the center position of the glass tube. The invention further provides a method for efficiently, stably and quantitatively testing permeability of the prime coat emulsified asphalt in the interior by using the tester. The method has the advantages that by means of the tester which is simple in structure, convenient to operate, efficient and stable, the permeable effects of the prime coat emulsified asphalt which is used on a base layer can be accurately simulated, so that quantitative evaluation of the permeability of the emulsified asphalt is achieved; and by means of the prime coat emulsified asphalt, firm adhering of a semi-rigid base layer and an asphalt concrete pavement is guaranteed, and service life of the asphalt pavement is guaranteed.
Description
technical field [0001] The invention relates to a test method for road pavement materials, in particular to a tester, and also relates to a quantitative test method using the tester to test the permeability of emulsified asphalt of a permeable layer. Background technique [0002] At present, semi-rigid base is generally used as the main load-bearing layer of pavement structure in our country, and it will still be used on a large scale in the future. Due to the different chemical properties of the semi-rigid base material and the asphalt pavement material, it is necessary to use the method of spreading emulsified asphalt on the surface of the semi-rigid base to solve the problem of interlayer bonding between the semi-rigid base and the asphalt concrete surface to ensure that the asphalt surface The layer and the semi-rigid base are better combined into a whole to prevent damage to the asphalt pavement, thereby prolonging the life of the asphalt pavement and improving the dura...
