Asphalt pavement paving method capable of reducing bubbles for highway engineering

Abstract

The invention discloses an asphalt pavement paving method capable of reducing bubbles for highway engineering. The asphalt pavement paving method comprises the following steps of when a base pavement is filled, removing organic residues in the range of a roadbed land and turf and surface soil below the original ground, and keeping the roadbed land dry so that pavement of the asphalt pavement cannot be damaged due to wet and moisture of the foundation after the pavement is finished; when an asphalt material is prepared, a trace amount of defoaming agent is added into the asphalt material, so bubbles are not easily generated after the asphalt pavement is paved, the construction quality and the use performance of the pavement are guaranteed, and initial pressing, re-pressing and final pressing are respectively performed after the asphalt pavement is finished; different rolling devices are adopted for primary rolling, secondary rolling and final rolling respectively, different methods are used for rolling for different times, and the mixture is leveled and stabilized, so that the mixture is compacted, stabilized and formed, a firm and stable pavement layer is obtained, wheel marks are eliminated, and finally a smooth pavement meeting the driving requirement is formed.

Description

technical field [0001] The invention relates to the technical field of asphalt pavement construction, in particular to an asphalt pavement laying method capable of reducing air bubbles for highway engineering. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but in addition to flexible materials, the base layer can also use rigid cement concrete or semi-rigid hydraulic materials. [0003] Bituminous concrete (bituminous concrete) is commonly known as asphalt concrete, artificially selected mineral materials with a cert...

AI Technical Summary

Problems solved by technology

[0008] Bubbles often appear in the asphalt pavement of the prior art during the laying process, which affects the stability of the pavement, greatly reduces the service life of the pavement, and easily causes traffic accidents if the pavement is damaged
