Asphalt foaming device and working method thereof

Abstract

The invention relates to the technical field of road engineering equipment, and discloses an asphalt foaming device. The asphalt foaming device comprises an asphalt tank, an asphalt pump, a centralized foaming module, a distributed foaming module, a shut-off valve and an operation platform; a first connection port of the asphalt tank is in communication with a feed end of the asphalt pump, a discharge end of the asphalt pump is in communication with a feed end of the centralized foaming module, a discharge end of the centralized foaming module is in communication with a feed end of the distributed foaming module, and a discharge end of the distributed foaming module is in communication with a second connection port of the asphalt tank; the shut-off valve is installed on a pipeline betweenthe discharge end of the distributed foaming module and the second connection port of the asphalt tank; and the asphalt tank, the asphalt pump, the centralized foaming module, the distributed foamingmodule and the shut-off valve are all connected to the operation platform. The invention further provides a working method of the asphalt foaming device. The asphalt foaming device has the beneficialeffects that a two-stage foaming function is achieved, and foamed asphalt with an excellent foaming effect can be prepared.

Description

technical field [0001] The invention relates to the technical field of road engineering equipment, in particular to an asphalt foaming device and a working method thereof. Background technique [0002] After a certain number of years, asphalt pavement will produce various types and different degrees of disease. Under the joint action of traffic and environment, the pavement material will gradually age, the overall strength of the road will decrease, and the damage will gradually increase. The development of pavement disease will seriously affect the normal use of the road. . There are two common solutions for traditional road maintenance: direct overlaying and digging and reconstruction. However, both of these two maintenance techniques have relatively large defects: directly adding a new structural layer on the original pavement does not eliminate the disease of the original pavement, but only temporarily covers it, and will raise the elevation of the pavement, making the ...

AI Technical Summary

Problems solved by technology

However, both of these two maintenance techniques have relatively large defects: directly adding a new structural layer on the original pavement does not eliminate the disease of the original pavement, but only temporarily covers it, and will raise the elevation of the pavement, making the pavement structure more complex. It will bring inconvenience to the maintenance and repair work in the follow-up operation; the maintenance method of excavation and reconstruction will generate a lot of waste during the construction process, and the stacking and storage of waste will also occupy a large amount of land resources, resulting in waste of resources and environmental hazards

[0003] Conventional maintenance and repair methods not only lead to the waste of a large amount of excavated and milled asphalt mixture, but also lead to excessive exploitation of new stone and asphalt resources, which is a great waste of resources, indirectly leading to the reduction of forest vegetation, soil erosion, and serious damage ecosystem
