Problems solved by technology
[0002] In the high temperature environment in Africa, and the airport road is exposed to the sun for a long time during the day, the road surface absorbs more heat, the temperature rises more, and the temperature drops more at night. Its own temperature changes greatly, which may easily cause irreparable cracks on the airport road, which will affect the service life. There are often problems with the airport road, and the degree of damage to the road structure has reached the level of unusable airport road. There is an urgent need to study a construction method that is simple and Repair methods that can extend the life of roads

Abstract
The invention discloses an airport asphalt pavement repairing method. The method comprises the following steps: milling both an asphalt layer and a concrete layer of an old pavement to expose the surface of a base layer; paving emulsified asphalt on the surface of the base layer, and compacting to form an emulsified asphalt layer; laying a heat absorption rod and fine sand on the surface of the emulsified asphalt layer and compacting to form a heat absorption layer, wherein the heat absorption rod comprises an ellipsoidal rubber shell, water contained in the rubber shell and a plurality of protrusions arranged on the outer surface of the rubber shell at intervals; and paving a heat insulation material on the surface of the heat absorption layer and compacting to form an asphalt pavement layer, wherein the preparation method of the heat insulation material comprises the following step of uniformly mixing leached cake and ceramic beads to obtain the heat insulation material, and the ceramic beads comprise a hollow ceramic shell and a radiation cooling heat insulation coating layer laid on the outer surface of the ceramic shell. The method has the beneficial effects of reducing the temperature rise degree of the paved asphalt pavement, thereby reducing the volume change degree and prolonging the service life of the road.
Description
technical field [0001] The invention relates to the field of airport asphalt pavement construction. More specifically, the present invention relates to a method for repairing airport asphalt pavement. Background technique [0002] In the high temperature environment in Africa, and the airport road is exposed to the sun for a long time during the day, the road surface absorbs more heat, the temperature rises more, and the temperature drops more at night. Its own temperature changes greatly, which may easily cause irreparable cracks on the airport road, which will affect the service life. There are often problems with the airport road, and the degree of damage to the road structure has reached the level of unusable airport road. There is an urgent need to study a construction method that is simple and Repair methods that can extend the life of roads. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems a...
