[0003] In related technologies, the mixing of the mixture is generally carried out at the construction site, and it is paved immediately after reaching the asphalt construction temperature to reduce the heat loss of the mixture. The requirements for temperature control and paving timing are very high, making the mixture Sufficient heating and stirring in a short period of time is particularly critical, while ordinary mixers stir the mixture by driving the shaft to rotate and drive the blades. room for improvement

Embodiment Construction
[0032] Attached to the following Figure 1-3 The present invention will be described in further detail.
[0033] The embodiment of the present invention discloses a construction method of an asphalt concrete pavement for a municipal road. refer to figure 1 , a construction method for municipal road asphalt concrete pavement comprises the following steps:
[0034] S1: Construction preparation: transport construction equipment such as transport vehicle 1, heating and stirring device 2, paver and other construction equipment to the construction site, and install the heating and stirring device 2 in the trunk of transport vehicle 1. The surface is thoroughly cleaned, and then 2-3 forest fire-fighting blowers are used to blow off the floating ash in a diagonal line in the longitudinal direction;
[0035] S2: Heating and stirring the asphalt mixture: Pour the asphalt mixture into the heating and stirring device 2, and the heating and stirring device 2 stirs the asphalt mixture an...

The invention discloses a construction method for asphalt concrete pavement of municipal roads. A stirring ring is arranged in a mixing tank. The axis of the mixing tank rotates, and the stirring blades of the stirring ring perform layered mixing on the asphalt mixture. The stirring ring rotates around its own axis under the drive of the second driving device, and the stirring blades of the stirring ring vertically stir the asphalt mixture. To mix each layer of asphalt mixture, when the first driving device and the second driving device drive the stirring ring to work at the same time, the stirring range of each set of stirring blades of the stirring ring can cover the inner cavity of the mixing tank, so that the asphalt mixture can be completely mixed. The azimuth three-dimensional stirring is beneficial to improve the stirring efficiency of the heating and stirring device, so that the asphalt mixture can be stirred more thoroughly.
Description
technical field [0001] The invention relates to the technical field of municipal road construction, in particular to a construction method of asphalt concrete pavement for municipal roads. Background technique [0002] The mixture required for the construction of the asphalt concrete pavement of the municipal road mainly includes the artificially selected aggregate with a certain gradation composition and a certain proportion of the road asphalt material, both of which need to be fully mixed at a temperature of 140-165 °C. [0003] In the related art, the mixing work of the mixture is generally carried out at the construction site, and paving immediately after reaching the asphalt construction temperature to reduce the heat loss of the mixture. The requirements for temperature control and paving timing are very high, making the mixture It is particularly important to heat and stir fully in a short time, while the ordinary mixer drives the shaft to rotate and drives the blade...
