Technical Field

[0001] The utility model relates to the technical field of cold recycled asphalt mixture production, and in particular to a water control system of a cold recycled asphalt mixture paver based on temperature perception. Background Art

[0002] Emulsified asphalt cold recycling technology uses emulsified asphalt as the binder of the recycled mixture. After the asphalt mixed recycled materials of the old asphalt pavement are excavated, recycled, crushed and screened, a small amount of new aggregate and a certain proportion of cold recycling agent are added according to the structural and functional requirements of the repaired road surface. It is a construction technology that mixes, spreads and rolls under natural conditions to form a recycled pavement structure layer.

[0003] However, in the actual construction process, it was found that under the influence of factors such as weather, temperature and the equipment's own operation, the mixing temperature of the cold recycled asphalt mixture changes greatly, which affects the optimal moisture content of the cold recycled asphalt mixture during the mixing process, resulting in low early strength and poor road performance of the cold recycled asphalt mixture, which directly affects its application effect and service life.

[0030] The water outlet module is communicatively connected with the control module, and the control module controls the water outlet speed of the water outlet module to control the moisture content of the cold recycled asphalt mixture.

[0031] By setting up a temperature collection module, a control module and a water outlet module, the mixing temperature of the cold recycled asphalt mixture is collected in real time, so as to determine the optimal moisture content of the cold recycled asphalt mixture at this time. The water outlet module is controlled by the control module to control the optimal moisture content of the cold recycled asphalt mixture according to the temperature, so that the cold recycled asphalt mixture always maintains the optimal moisture content during the mixing process, which is conducive to the control of the optimal compaction degree on site, thereby ensuring the construction quality of on-site cold recycling.

[0032] like Figure 2 As shown, in this embodiment, the control module includes an input unit, through which the functional relationship between the mixing temperature and the optimal moisture content is input, and the control module determines the corresponding optimal moisture content through the functional relationship and the collected temperature.

[0037] By setting a flow valve and a water storage unit, the flow valve controls the water outlet speed of the water storage unit. The water storage unit stores water inside in advance. The water storage unit can be set on the asphalt mixture paver or an independent device can be set outside the paver to adapt to different construction environments and conditions.
