Problems solved by technology

The mixing temperature of hot-mix asphalt mixture is usually between 150°C and 180°C. The pavement after construction has good road performance, but the construction process consumes a lot of energy, emits harmful gases, and endangers the health of workers. At the same time, the construction process It also exacerbates the aging of asphalt and reduces the service life of the pavement

Abstract

The invention provides a foam warm-mix asphalt water control metering system, which includes a water storage tank, the water outlet of the water storage tank is connected with a liquid pump, and also includes a control device, a detection device for detecting the amount of asphalt additive in an asphalt foamer, and The liquid delivery branch connected to the liquid outlet of the liquid pump and the liquid return branch, the liquid delivery branch is connected to the asphalt foamer, the control device is used to obtain the measurement information of the detection device, And according to the detection information of the detection device, the liquid delivery branch and the liquid return branch are switched and connected, and the control device detects the amount of asphalt added in the asphalt foamer to control the amount of water added, and the asphalt foamer stops working Finally, the third electromagnetic switch can be turned on to make the water flow back to the water storage tank through the return flow branch, so that the amount of water added can be adjusted in real time according to the working state of the asphalt foamer to ensure the working quality of the asphalt foamer.

Description

technical field [0001] The invention generally relates to the technical field of foam warm-mix asphalt water adding system, in particular to a foam warm-mix asphalt water adding control and metering system. Background technique [0002] Asphalt mixture hot mixing process is the most commonly used asphalt pavement construction process in my country. The mixing temperature of hot-mix asphalt mixture is usually between 150°C and 180°C. The pavement after construction has good road performance, but the construction process consumes a lot of energy, emits harmful gases, and endangers the health of workers. At the same time, the construction process It also exacerbates the aging of asphalt and reduces the service life of the pavement. The transportation construction industry is facing severe challenges in terms of environmental pollution and resource consumption. For this reason, the semi-flexible pavement technology of the foamed warm asphalt mixture matrix has been proposed in...
