Embodiment 1

[0030] figure 1 The block diagram of the steps of the asphalt mixture compaction process that the embodiment of the present invention provides; figure 1 Shown, the asphalt mixture compaction technology provided by the invention comprises the following steps:

[0031] Initially press the paved asphalt mixture with a rubber-tyred road roller;

[0032] Recompact the asphalt mixture with a rubber-tyred roller or a double-steel roller;

[0033] Final compaction of the asphalt mixture with a tandem roller.

[0034] Further, before the step of rolling the paved asphalt mixture with a rubber-tyred roller, it also includes: coating the tires of the rubber-tyred roller with an anti-adhesive agent.

[0035] Wherein, 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-tyred road roller rolls, the anti-adhesive agent is sprayed on the waterproof cloth laid o...

Embodiment 2

[0052]On the basis of the above embodiments, further, the present invention also provides a pavement construction method, including the asphalt mixture compaction process provided in Embodiment 1. During use, the rubber-tyred roller can change the inflation pressure according to the actual demand to change the ground pressure, that is, the pressure of the rubber-tyred roller on the asphalt mixture can be greater than that of the double-steel roller on the asphalt mixture. In addition, during the compaction process, the rubber-wheeled road roller can carry out kneading and pressing, 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 compacted layer can be evenly compacted. Then, the asphalt mixture is re-pressed with a rubber-tyred roller or a double-bar roller, and finally the asphalt mixture is finally compacted with a double-steel roller, and the compaction steps are repeated to further ...

Abstract

The invention provides an asphalt mixture compaction process and a pavement construction method, and relates to the technical field of highway construction. The asphalt mixture compaction process comprises the following steps: performing initial compaction on a paved asphalt mixture by using a rubber tire roller; repressing the asphalt mixture by using a rubber tire road roller or a double-steel-wheel road roller; and performing final pressing on the asphalt mixture by using the double-steel-wheel road roller. By adopting the combination of the grinding modes, in the initial pressing process,fine cracks can be avoided, mucilage formed by asphalt, a mineral powder, fine aggregate and the like in the mixture can float upwards, the upper surface is tighter, and waterproofness is better.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an asphalt mixture compaction process and a road surface construction method. Background technique [0002] The compaction of asphalt mixture is an important process in the construction of asphalt concrete pavement, and the compaction quality of asphalt mixture is very important to ensure the quality of asphalt pavement construction. [0003] In the prior art, after the paving of the asphalt mixture is completed, the asphalt mixture is initially pressed by a double-drum road roller. However, in the process of initial pressure, there will be a phenomenon of shifting, that is, the mixture on the front side of the drum will move laterally after being pressed. This compaction method may cause cracks on the pavement, which will affect the construction quality of the pavement, and then affect the service life of the pavement. Contents of the invention [0004] The purpose...
