Abstract

The invention discloses a using method of an asphalt module for self-binding road repair, and relates to the field of municipal road maintenance. The using method comprises the steps that (1) a groovewith a regular shape is formed in a road to be repaired; (2) the asphalt module which is matched with the shape of the groove is cut between two adjacent U-shaped structures on a whole asphalt modulein the direction perpendicular to a conductor II, and is placed into the groove; (3) the asphalt module after being cut is connected with positive and negative poles of the two ends of a farthest tungsten filament through the conductor I to be connected with a municipal power supply; (4) a tungsten filament layer after being electrified transfers heat to an asphalt base layer, asphalt in the high-temperature asphalt base layer is melted, and then the asphalt module is tightly bonded to an original rod; (5) the power supply is disconnected, and the conductor I is recycled; and (6) the asphaltmodule is compacted by adopting a conventional process. The strength of a composite nonwoven fabric which is formed by compounding a spunbonded nonwoven fabric layer, a reinforced mesh layer and a melt-blown nonwoven layer is greatly increased. The asphalt module is suitable for small range repair, the asphalt module is put into a section which needs to be repaired, the asphalt is melted by electrification and heating, so that the repairing function and the effects of compression resistance, resistance to deformation and durability are achieved; and the tungsten layer is added, the asphalt issoftened by heating of the tungsten layer, a traditional technology is replaced, and more convenience is achieved.

Description

[0001] Name of the invention of the original application: self-adhesive asphalt module for road repair [0002] Original application application number: 2016110208880 [0003] The original application filing date: 2016.11.21. technical field [0004] The invention relates to a self-adhering asphalt module for road repair, which relates to the field of municipal road repair. Background technique [0005] At present, when repairing roads, asphalt repair is often used, but rapid damage after repair often occurs. The main reason is that the repair layer does not fit the original asphalt layer and base layer, or the temperature during repair is not suitable, the temperature is too low, and the repair layer is not combined with the original asphalt layer and base layer. After being rolled for a long time, the surface layer falls off. The conventional process is to pour the heated asphalt into the designed pit for compaction. This method is also limited by the weather, and the ...
