Abstract

The invention aims to provide a vacuum bitumen stirring machine. The technical scheme of the invention is as follows: the vacuum bitumen stirring machine comprises a machine box, wherein a stirring device is mounted on the machine body; support legs are arranged at the bottom of the machine body; an feed port is formed on the side wall of the machine body. The vacuum bitumen stirring machine is characterized by further comprising a vacuum pump; connecting ports are formed in the surface of the machine body; the vacuum pump is connected with the connecting ports through pump pipes; and a pressure valve is arranged at the top end of the machine body. The vacuum bitumen stirring machine has the benefits as follows: bitumen is stirred under a vacuum condition; contact and adhesion between the bitumen and the inner wall of the machine body are reduced; the maintaining and cleaning time after use is reduced; and the working efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of road construction engineering, in particular to a vacuum asphalt mixer. Background technique [0002] Asphalt concrete, English name: bituminous concrete, commonly known as bituminous concrete, is a combination of artificially selected mineral materials with a certain grade composition (gravel or crushed gravel, stone chips or sand, mineral powder, etc.) and a certain proportion of road asphalt Material, a mixture made under strictly controlled conditions. [0003] The strength of asphalt mixture is mainly manifested in two aspects. One is the cohesive force of the cement formed by asphalt and mineral powder; the other is the internal friction and locking force between the aggregate particles. The huge surface area of ​​fine mineral powder particles (mostly less than 0.075 mm) makes the asphalt material form a thin film, thereby improving the bonding strength and temperature stability of the asphalt material; ...
