DETAILED DESCRIPTION

[0022] The specific implementation of the utility model is further explained in detail. Figure 1 The specific implementation of the utility model is further explained in detail.

[0023] In practical implementation, this utility model discloses a distributed vibration-mixing foamed asphalt in-situ cold recycling system, comprising a water supply module 1, a milling module 2, an aggregate spreading module 3, a cement slurry preparation module 4, an asphalt heating and transportation module 5, a stockpile conveying and sweeping module 6, a foamed asphalt vibration mixing module 7, a paving module 8, a rolling module 9, and a road surface heating module 10, as well as a control system for controlling the operation of each module. The milling module 2 is mainly used for cutting and crushing the old asphalt pavement. The heating module is equipped with a heater for heating the recycled pavement. The water supply module 1 provides water for milling operations to the milling module 2. The asphalt heating and transportation module 5 includes an asphalt storage tank. The system includes an asphalt filling and circulation system, a generator set, a vertical shaft mixer, an admixture delivery and metering system, a control system, an overflow interface, and a self-driving chassis. These components are used to supply base asphalt to the foamed asphalt vibration mixing module 7. The cement slurry preparation module 4 supplies asphalt foaming water and cement slurry for recycled mixture production to the foamed asphalt vibration mixing module 7. The stockpile conveying and cleaning module 6 is used to clean and collect the milled old asphalt material and transport it to the foamed asphalt vibration mixing module 7. The foamed asphalt vibration mixing module 7 is used for asphalt foaming and recycled material preparation. The paving module 8 is used for paving the recycled material. The rolling module 9 is used for compacting the paved recycled pavement.

[0024] First, the water supply module 1 and the milling module 2 cooperate to complete the road milling operation. During actual construction, the water supply module 1 and the milling module 2 sequentially and in the same direction enter the road surface to be milled. The water supply module 1 supplies water to the milling module 2 through a pipeline. The milling module 2 mills the old asphalt layer of the original road surface. Preferably, the milling module 2 uses a forward milling method. The milled material is discharged from the middle of the milling rotor of the milling module. In this embodiment, the milling operation is carried out separately from the road recycling operation. Traditional cold road recycling often uses Wirtgen milling machines. In this type of construction, the milling rotor of the milling machine mills counterclockwise and mixes the material while milling. During operation, the newly added aggregate will be cut by the milling rotor, resulting in… Lower aggregate particle size affects gradation. In this embodiment, a modified milling module can be used for climb milling, which allows control of the material particle size gradation by controlling the travel speed of the milling module. In other words, the crushing time of the material can be controlled by adjusting the ground clearance, rotation speed, and travel speed of the milling rotor, thereby controlling the particle size. This not only improves the quality of the recycled pavement but also requires only a small amount of new aggregate or even no new aggregate to adjust the particle size ratio. Specifically, the milling module 2 has a cutter head spacing of 15 cm, a pitch of 400 cm, a rotor diameter of 1.4 m, and a rotation speed of 110 m / min. By increasing the working speed of the climb milling rotor and optimizing the cutter head spacing and helical arrangement, the gradation can be improved.

[0025] In addition, a particle size detection system is arranged at the rotor of the milling module 2, and the travel speed of the milling module 2 is automatically controlled according to the scanning result of the particle size detection system, so as to control the particle size grading of the old asphalt and old materials.

The travel speed of the milling module 2 is adjusted by the particle size determination and detection result of the control system, so as to achieve the effect of adjusting the particle size grading. Preferably, the travel speed of the milling module 2 is controlled at 3.5-4 meters per minute. In addition, in the system, the milling and regeneration are carried out step by step in order to control the grading of the materials, so as to completely mill the road surface to be regenerated first and then uniformly regenerate. The current pavement regeneration is single-lane edge milling and edge regeneration. The present process allows multiple lanes to be milled first and then uniformly regenerated, thereby improving the operation efficiency. According to the actual road conditions, the width of the milled road surface is adjusted, and the applicability is better than the existing pavement regeneration process.

[0026] After the milling of the road surface to be regenerated is completed, the particle size grading of the milled material is screened, and according to the laboratory designed mixing ratio (the designed mixing ratio should meet the requirements of the grading of the recycled aggregate in the line standard), the missing particle size aggregate is uniformly and continuously spread on the milled material by the stone spreading module 3 according to the proportion, and then the recycled aggregate is uniformly and continuously collected along the direction of the road to be paved, and the area without the accumulation of the recycled aggregate is cleaned.

In the present application, it also includes an aggregate module, which is used to collect the milled material after milling to the middle position of the road where the milling is completed.
