Problems solved by technology

[0002] Noise-reducing asphalt concrete is a kind of concrete with elastic pavement prepared by using asphalt as the main raw material. It mainly uses its elasticity to convert vibration into inaudible infrasonic waves, which improves the noise reduction ability compared with other road surfaces. However, the surface is in production There is usually a lack of more standardized data in the process, which makes it difficult to control the production quality index and the error of the production quality index becomes larger. Therefore, a device that can alleviate the above problems is urgently needed

Abstract

The invention discloses a manufacturing method of noise-reducing asphalt concrete. The manufacturing method comprises the following steps: preparation of 60 parts of first asphalt, 25 parts of secondasphalt, 10 parts of an SBS modifier, 9 parts of engine oil and 14 parts of talc powder, wherein the first asphalt is 10 # asphalt, the second asphalt is 100 # asphalt, the engine oil is used as a softener, the engine oil is used in an oil coating step; stirring; colloid grinding; preparation of a base; oil immersion; oil coating; and drying. Before the step of stirring is performed, the first asphalt, the second asphalt, the SBS modifier, the engine oil and the talc powder are put into a target stirrer, and are stirred through the stirrer. With the manufacturing method, the stability of production quality can be improved, and use requirements on asphalt concrete can be better met.

Description

technical field [0001] The invention relates to the technical field of a method for making noise-reducing asphalt concrete, in particular to a method for making noise-reducing asphalt concrete. Background technique [0002] Noise-reducing asphalt concrete is a kind of concrete with elastic pavement prepared by asphalt as the main raw material. It mainly uses its elasticity to convert vibration into inaudible infrasonic waves. Compared with other road surfaces, it improves the noise reduction ability. However, the surface is in production There is usually a lack of more standardized data in the process, which makes it difficult to control the production quality index and the error of the production quality index becomes larger. Therefore, a device that can alleviate the above problems is urgently needed. Contents of the invention [0003] The object of the present invention is to provide a noise reduction asphalt concrete production method to solve the problems raised in th...
