Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the structure of the present invention includes two systems, one is an emulsified asphalt flushing system, and the other is an emulsified asphalt evaporation system. The former system has a vibrator base (7), and the base (7) is set There is a conical sieving seat (6), and a sieve (5) is arranged on the conical sieving seat (6). The sieve (5) is a square-hole aggregate sieve with a diameter of 30 cm. The size of the sieve holes from top to bottom is 4.75mm, 1.18mm, 0.075mm three gears. The sieve (5) is fixed by locking bolts (3). The upper part of the sieve is provided with a spray cover (4). In order to obtain a more ideal spray effect, an upper liquid pump (2 ) to pressurize the water, the upper liquid pump (2) is connected to the water pipe (1). Put the emulsified asphalt cold recycled mixture in the sieve (5), pressurize the w...

Abstract

The invention provides a determination method and a determination instrument for the content of emulsified asphalt of an emulsified asphalt cold-recycling mixture, and belongs to the technical field of determination of engineering materials. The emulsified asphalt cold-recycling mixture is put into a sieve and water is pressurized to be sprayed so that the water is sprayed out in a mist manner; the sprayed water is used for washing the emulsified asphalt cold-recycling mixture on the sieve and the emulsified asphalt in the emulsified asphalt cold-recycling mixture is washed out; then a washed emulsified asphalt mixed solution is collected and is stirred and heated, wherein the heating temperature is not more than 120 DEG C; and finally, the content of the asphalt in evaporated residues of the emulsified asphalt mixed solution is determined to determine the use amount of the emulsified asphalt in an emulsified asphalt cold-recycling process. The reasonable debugging and operation are carried and an asphalt extractor is matched for use so that the content of the emulsified asphalt in the emulsified asphalt cold-recycling mixture can be effectively determined.

Description

technical field [0001] The invention belongs to the technical field of measuring engineering materials, and in particular relates to a method for measuring the content of emulsified asphalt in emulsified asphalt cold recycled mixture and a measuring instrument thereof. Background technique [0002] The emulsified asphalt cold recycling technology is to mill, crush and sieve the old pavement of the original pavement, evaluate and analyze the sieved old pavement materials through certain means, and then add some new materials according to a certain ratio. A certain amount of emulsified asphalt is added, and the regenerated mixture is spread on the road base with strength and smoothness that meet the specification requirements, and then rolled to make it meet the performance requirements of asphalt pavement. As a new type of road construction material, emulsified asphalt cold recycled mixture can consume a large amount of old asphalt pavement materials compared with thermal rec...
