Embodiment Construction

[0036]In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0037] like Figure 1 to Figure 9 Shown, a kind of asphalt concrete preparation method, it uses a kind of input type mixing equipment, this input type mixing equipment includes mixing drum 1, mixing device 2, electric slider 3, moving frame 4 and input device 5, adopts the above input The preparation method of asphalt concrete by type mixing equipment is as follows:

[0038] S1, put in: put the filling amount (stone powder) into the input cavity 53, dry the sand, and put it into the input cavity 54;

[0039] S2. Temporary storage: heating and melting the asphalt to make it viscous, ...

Abstract

The invention provides an asphalt concrete preparation method, and the method is implemented by matching a mixing drum, a mixing device, an electric sliding block, a moving frame and an input device, and can solve the problems that in the traditional mixing process, as the filling amount (stone powder) and sand are small solid particles, and asphalt is a viscous substance; after the solid particles enter the viscous asphalt, the position cannot be changed easily; the problems that the filling amount and sand are liable to accumulate in asphalt due to the fact that raw materials are generally poured into the asphalt in sequence in a large batch in an existing pouring mode, and the specified uniformity degree can be possibly achieved only by long-time stirring even if a mechanical stirring mode is used are solved.

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 the viscous asphalt, filling amount, and sand. The traditional method usually pours the three manually one after another. into the mixing drum, and then mechanically agitated. [0003] However, due to the filling amount (stone powder), the sand is a small solid particle, and the asphalt is a viscous substance, when the solid particle enters the viscous asphalt, it...
