A method for manufacturing emulsified asphalt slurry and injecting slurry into longitudinal cold joints of pavement

Abstract

The invention discloses a method for producing emulsified asphalt slurry and pouring slurry into longitudinal cold joints of road surfaces, which belongs to the field of road joint filling in road construction. The technical problem to be solved by the invention is how to quickly and accurately complete cold joints The slurry infusion at the seam splicing place is used to improve the quality of the joint. The technical scheme adopted is as follows: the method is as follows: S1. Add the required cement and emulsified asphalt to the slurry processing device; S2. Turn on the power and power generation device, wait for After the power and power generation device is running stably, turn on the whey processing device, and the whey processing device completes the mixing of whey according to the slow-medium-fast stirring mode, and maintains a continuous slow stirring state; S3, open the control system, the vehicle Walking and slurry discharge are controlled by one person, who opens the walking device; another person controls the grout injection device, and this person aligns the pouring rod assembly with the seam, and at the same time opens the drainage assembly, and the slurry is guided into the injection rod assembly through a soft catheter. In the pulp head.

Description

technical field [0001] The invention relates to the field of road joint grouting in road construction, in particular to a method for producing emulsified asphalt slurry and pouring the grout into longitudinal cold joints of road surfaces. Background technique [0002] With the gradual increase of road reconstruction and expansion technology in recent years, there are more and more longitudinal overlaps of old and new road structures, mainly involving the lapping of new and old water-stabilized bases, the lapping of old water-stabilized bases and asphalt cold recycled materials, and the old asphalt pavement Lap with asphalt cold recycled material. However, in the existing pavement design, there is no special design and special equipment for splicing. In the design of road structure, ensuring the integrity of the road structure layer is the key to ensuring the service life of the road, and the splicing of roads in reconstruction and expansion is prone to large longitudinal in...
