A kind of asphalt concrete preparation method

Abstract

The invention provides a method for preparing asphalt concrete. The operation is completed by the cooperation of a mixing drum, a mixing device, an electric slider, a moving frame and an input device. The invention can solve the problems caused by the filling amount (stone powder), sand It is a small solid particle, and asphalt is a viscous substance. When the solid particle enters the viscous asphalt, it is difficult to change its position. However, the existing pouring method usually pours raw materials in large quantities sequentially, resulting in filling volume, Sand is easy to pile up inside the asphalt, even if mechanical agitation is used, it takes a long time for agitation to achieve the required uniformity.

Description

technical field [0001] The invention relates to the technical field of asphalt concrete preparation, in particular to a preparation method of asphalt concrete. Background technique [0002] Asphalt concrete is a mixture made of asphalt and a certain proportion of aggregate. It is widely used in road paving. It has smooth surface, no joints, comfortable driving, small vibration, low noise, wear resistance, no dust and easy cleaning Short construction period, easy maintenance and repair, renewable utilization, suitable for phased construction, etc. In the process of preparing asphalt concrete, it is necessary to mix viscous asphalt, filler, and sand. The traditional method usually pours the three manually one after another. into the mixing drum, and then mechanically agitated. [0003] However, since the filler (stone powder) and sand are small solid particles, and the asphalt is a viscous substance, when the solid particles enter the viscous asphalt, it is difficult to chang...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a method for preparing asphalt concrete, which can solve the problem of filling material (stone powder) and sand being small solid particles and asphalt being a viscous substance in the traditional mixing process. After viscous asphalt, it is difficult to change the position, and the existing pouring method usually pours raw materials in large quantities sequentially, resulting in the accumulation of fillers and sand in the asphalt, and it takes a long time even if mechanical agitation is used. It is possible to achieve the specified uniformity by stirring for a certain period of time.
