Problems solved by technology

[0004] The invention provides a modified emulsified asphalt preparation process, the purpose of which is to solve the following problems in the modified emulsified asphalt preparation process: (1) when cutting cylindrical asphalt blocks, it is difficult to ensure that the asphalt blocks are cut into uniform volumes As a result, some larger asphalt pieces cannot be fully melted when the asphalt pieces are heated and melted; (2) At present, when inserting holes on the surface of the asphalt pieces, it is impossible to ensure that the holes are evenly distributed on the surface of the asphalt pieces. It is easy to cause the part on the asphalt block to not be fully melted

Embodiment Construction

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0033] Such as figure 1 As shown, this embodiment provides a modified emulsified asphalt preparation process, comprising the following steps:

[0034] Step 1. Cut off the surface of the asphalt block: cut off the surface of the cylindrical asphalt block to remove the oxide layer and stains on the surface.

[0035] Step 2: Cutting into small pieces of asphalt: cutting the asphalt block removed from the surface layer into small pieces, and inserting holes on the surface of the small piece of asphalt.

[0036] Step 3, emulsification after heating and melting: heat the cut asphalt pieces into a molten state, and then add emulsifier. Stir the mixture of asphalt and emulsifier evenly to obtain asphalt emulsion. Cool the molten bitumen emulsion to solid...

Abstract

The invention belongs to the technical field of asphalt preparation, and particularly relates to a modified emulsified asphalt preparation process which comprises: 1, asphalt block surface layer cutting: cutting off the surface layer of a cylindrical asphalt block to remove the oxide layer and the stain on the surface; 2, cutting into small asphalt blocks: cutting the asphalt blocks of which the surface layers are cut into small blocks, and inserting holes in the surfaces of the small asphalt blocks; 3, emulsifying after heating and melting: heating the cut small asphalt blocks into a molten state, and then adding an emulsifier; uniformly stirring a mixed solution of asphalt and an emulsifier to obtain the asphalt emulsion; cooling the asphalt emulsion in the molten state to a solid state.Step 2 is completed by adopting a modified emulsified asphalt preparation device in a matching manner. Asphalt blocks can be cut into small blocks uniform in size, and insertion holes are evenly distributed in the surfaces of the small asphalt blocks.

Description

technical field [0001] The invention belongs to the technical field of asphalt preparation, and in particular relates to a preparation process of modified emulsified asphalt. Background technique [0002] Modified emulsified asphalt is an asphalt emulsion formed by adding a small amount of emulsifier to asphalt and dispersing the asphalt in fine droplets in water through mechanical action. Modified emulsified asphalt has good durability and wear resistance. The excellent quality of modified emulsified asphalt effectively enhances the load capacity of the road surface, reduces the fatigue of the road surface caused by overloading, and prolongs the service life of the road surface exponentially. It is widely used in the paving of high-grade highways, airport runways and bridges. When preparing the modified emulsified asphalt, it is necessary to first cut the asphalt block, then pierce the surface of the cut bitumen block, and then melt the cut bitumen block into a molten stat...
