High-flatness construction method for asphalt pavement

Abstract

The invention discloses a high-flatness construction method for an asphalt pavement, belongs to the technical field of asphalt construction, and aims to improve the distribution phenomenon and facilitate the subsequent rolling quality by uniformly carding asphalt materials by utilizing a material carding net in the process of paving the asphalt materials. During initial pressing, through the arranged marking material barrel and the novel hot rolling roller, marking treatment is conducted on the uneven position while rolling is conducted, targeted multiple times of rolling and flattening are conducted conveniently, and in the rolling process of the novel hot rolling roller, once the novel hot rolling roller encounters the uneven position, by means of the inclination characteristic of the novel hot rolling roller, the heat control floating ball of the internal heat conductor automatically floats upwards and then drives the heat to gather towards the high position, so that the rolling effect on the asphalt material at the high position is promoted, the leveling efficiency is improved, the uneven position can be leveled in a targeted mode during re-pressing, and compared with the prior art, the rolling frequency can be reduced, and the high rolling effect is achieved.

Description

technical field [0001] The invention relates to the technical field of asphalt construction, in particular to a construction method with high smoothness of asphalt pavement. Background technique [0002] Asphalt pavement is various types of pavement formed by paving and rolling asphalt concrete. Asphalt concrete is a mixture formed by fully mixing asphalt materials with a certain viscosity and appropriate dosage and mineral aggregates of a certain grade. Asphalt concrete, as an asphalt pavement material, has to bear the repeated action of running vehicle loads and the long-term impact of environmental factors during its use. Therefore, while asphalt concrete has a certain bearing capacity, it must also have good durability against natural factors. That is to say, it should be able to show sufficient stability in high temperature environment, crack resistance in low temperature condition, good water stability, long-lasting anti-aging and good anti-skid property to ensure as...

Problems solved by technology

[0004] However, when rolling asphalt materials, due to various reasons, the unevenness of the road surface is prone to low flatness during rolling, which requires repeated rolling or manual local leveling, which will undoubtedly seriously slow down the construction. progress, and because of the difficulty of measuring work, it is difficult to effectively roll and level the unevenness
