[0029] Example 1
[0030] figure 1 The block diagram of the steps of the asphalt mixture compaction process provided by the embodiment of the present invention; such as figure 1 As shown, the asphalt mixture compaction process provided by the present invention comprises the following steps:
[0031] Use rubber wheel rollers to initially press the paved asphalt mixture;
[0032] Use rubber wheel rollers or double drum rollers to re-press the asphalt mixture;
[0033] The final pressure of the asphalt mixture is carried out with a twin drum roller.
[0034] Further, before the step of rolling the paved asphalt mixture with a rubber-tired road roller, the method further includes: coating an anti-adhesive on the tires of the rubber-tired road roller.
[0035] Among them, the anti-adhesive agent is an oil-water mixture, a mixture of vegetable oil and water can be selected, and diesel oil is avoided for mixing.
[0036] Specifically, before the rubber-tired road roller is rolle...
Example Embodiment
[0051] Example 2
[0052]On the basis of the foregoing embodiments, the present invention further provides a pavement construction method, including the asphalt mixture compaction process provided in Embodiment 1. In the process of use, the rubber wheel roller can change the inflation pressure according to the actual demand to change the ground pressure, that is, the pressure of the rubber wheel roller to the asphalt mixture can be greater than the pressure of the double drum roller to the asphalt mixture. In addition, in the process of compaction, the rubber wheel roller can perform kneading, that is, it has a kneading effect, so that the particles of the compacted layer can be fitted with each other without being damaged, and the particles can be evenly compacted. Next, the asphalt mixture is re-pressed with a rubber wheel roller or a double-bar roller, and finally the asphalt mixture is subjected to final compression and surface compaction with a double-drum roller, and the...
