Problems solved by technology

Li Bo of Lanzhou Jiaotong University and others invented a tester for the demulsification speed of emulsified asphalt. Although the current value is also used to characterize the demulsification speed of emulsified asphalt, it measures the current value by applying a voltage to the emulsified asphalt emulsion. The motor current changes in the stirring process are essentially different

Abstract

The present invention discloses a device for determination of emulsified asphalt demulsification time on the basis of current value, and belongs to the technical field of asphalt, and the device includes a frame, a fixed rack, an asphalt pump, an asphalt storage tank, an asphalt conveying pipe, a variable speed motor, a drive shaft, a sample containing barrel, an asphalt nozzle, a stirring paddle, a fixed seat, a control base, a digital display screen, a control panel, a current meter, a power supply and a microprocessor. Through use of the getting bad mixing workability characteristic of gradual emulsified asphalt demulsification of the device for determination of emulsified asphalt demulsification time on the basis of current value, the current meter connected with the variable speed motor is used for measurement of current change caused by variable speed motor power compensation for determination of the emulsified asphalt demulsification time.

Description

technical field [0001] The invention belongs to the technical field of asphalt, in particular to a device for measuring the breaking time of emulsified asphalt based on the current value. Background technique [0002] Emulsified asphalt is a commonly used pavement material. It is mostly used as road maintenance asphalt, sticky layer oil, seal oil, etc. Emulsified asphalt needs a certain period of time to demulsify, and the demulsification speed is different due to different uses. In the current construction process, it is necessary to wait for the emulsified asphalt to break before continuing construction. The test method for the emulsified asphalt demulsification speed given in JTJE20-2011 "Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering" formulated in 2011 in my country can only Qualitatively, the demulsification speed of emulsified asphalt is divided into fast cracking, medium cracking and slow cracking. Li Bo of Lanzhou Jiaotong University and ot...
