Description

technical field

[0001] The invention relates to the technical field of expressways, in particular to a rapid spraying device for asphalt in a permeable layer for expressways. Background technique

[0002] Asphalt concrete is often used as the pavement material in the construction of expressways. In order to ensure that the asphalt concrete can be well combined with the base material during asphalt pavement construction, liquid petroleum asphalt, emulsified asphalt, and coal tar pitch are generally sprayed on the base. A thin layer that goes deep into the surface of the base layer to a certain depth to form a permeable layer. During the construction of the permeable layer, a spraying device is generally used to spray the asphalt.

[0003] For example, application number: CN201610691942.8 The present invention relates to a permeable asphalt spraying device for expressways, in particular to a rapid asphalt spraying device for expressways. The technical problem to be solved by ...
