noise reduction type asphalt pavement reinforcement and Method for Fabricating the same

摘要

A method of manufacturing a noise-reduced asphalt pavement reinforcement material. The present invention provides a sheet conveying method comprising the steps of: feeding a first sheet unwound from a first material roll to a sheet conveying unit; Dropping a certain amount of sound absorbing nano powder from a powder supply portion provided directly above the sheet conveying portion to the upper surface of the first sheet in a state where the one-way conveyance of the first sheet is temporarily stopped in the sheet conveying portion; Supplying and laminating a second sheet unwound from a second material roll to an upper surface of a first sheet conveyed along the sheet conveying portion so as to cover the sound absorbing nano powder dropped on the upper surface of the first sheet; Wherein the first sheet and the second sheet are in a state of temporarily stopping the first sheet and the second sheet in the sheet conveying section, and the first sheet and the second sheet are separated from each other by the ultrasonic welder corresponding to the absorbing nano- A step of forming a joint for integrally fusing the first and second sheets with ultrasonic vibration energy and a step of forming a laminated sheet for forming pockets for accommodating the sound absorbing nano powder interposed between the first and second sheets, And winding the roll in a roll form in the winding roll.
