Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an additive for mixing asphalt,

The present invention relates to an additive mixing and heating apparatus for producing asphalt asphalt, and more particularly, to a mixer and a heating apparatus for mixing asphalt asphalt with an asphalt material produced in a general asphalt plant. And an additive mixing and heating device for goeth asphalt production.

Generally, asphalt is used for road pavement. Among these asphalt, there is goosal asphalt (mastic asphalt) in which natural asphalt and additive (admixture) are mixed at a certain ratio to general asphalt and general asphalt.

In particular, the Guss asphalt is used in a paving method that does not require a separate compaction operation because of its excellent adhesiveness and fluidity. It is impervious, has a large waterproofing effect, is highly adaptable to bending, It is mainly used for bridge pavement of concrete high-rise bridges, cold pavement pavement, sidewalk pavement, building floor pavement and so on.

However, the goos asphalt is produced by mixing natural asphalt with natural asphalt and additives at a certain ratio and heating the mixture to a predetermined temperature. To produce such goos asphalt, the equipment and structure of a conventional asphalt production plant are changed and used After the production of goose asphalt, it is required to be re-constructed into a general asphalt production plant. Therefore, there is a problem in that the production of asphalt is difficult and the productivity is not improved.

Conventionally, in order to produce goos asphalt, the existing asphalt production plant (existing asphalt mixing plant) is modified to fit the production of goose asphalt, and the goos asphalt is produced by retrofitting the system or reinforcing the system. However, It is disadvantageous in that the asphalt material and the goose asphalt are heated by mixing the additive in the same plant so that the goose asphalt material may be altered.

In addition, most of the asphalt production plants in each region can not properly retrofit the equipment for producing goos asphalt. Even if the asphalt production plant is remodeled, the asphalt production plant can not be remotely located Therefore, there is a difficulty in moving the goose asphalt to the site of road pavement.

Therefore, it is required to develop a technique for mixing and heating a mobile additive capable of producing goose asphalt without changing the equipment and structure of a general asphalt production plant.
