Example Embodiment

[0045] The present invention will be described in detail below with specific embodiments, wherein the exemplary embodiments and descriptions are only used to explain the present invention, but are not intended to limit the present invention.

[0046] A kind of airport asphalt concrete pavement preventive maintenance method described in this specific embodiment adopts the following steps:

[0047] Step 1: crack treatment, adopt the following steps:

[0048] Crack classification: Asphalt pavement damage can be generally divided into functional attenuation and structural damage classification. The former is manifested as a decrease in pavement service capacity, flatness and anti-skid performance; Cracks are one of the most common, most prone and earliest diseases in all kinds of damage to asphalt pavement. It accompanies the entire service life of asphalt pavement and increases with the age of the road. aggravate;

[0049] Equipment preparation: slotting machine, caulking machine...

Abstract

The invention relates to the technical field of road pavement maintenance, in particular to an airport asphalt concrete pavement preventive maintenance method. The airport asphalt concrete pavement preventive maintenance method comprises the following steps of 1, crack treatment, wherein the following steps are adopted: 1) preparation stage before construction, 2) grooving stage, 3) crack cleaningand drying stage, 4) crack pouring operation stage, and 5) crack pouring quality detection stage; 2, pit slot treatment, wherein the following steps are adopted: 1) construction preparation, 2) division of a digging and repairing range, 3) excavation of a pit slot, 4) cleaning of the pit slot, 5) spreading of tack coat, 6) back-filling and rolling of an asphalt mixture, and 7) sealing joint waterproof treatment; and 3, asphalt pavement recycling seal. The airport asphalt concrete pavement preventive maintenance method has the advantages that the road condition can be improved, the running quality can be improved, the service life of a pavement can be prolonged, and the live cycle cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of road pavement maintenance, in particular to a preventive maintenance method for airport asphalt concrete pavement. Background technique [0002] With the development of society, people's travel tools have also undergone major changes, and airplanes have been widely used as an efficient and fast means of transportation. In order to promote the sustained and rapid development of the national economy, the field of infrastructure construction is still the key support direction of the country's medium and long-term development plan. Air transport is increasingly valued for its efficient and fast operation mode and important strategic value. Therefore, in recent years, new construction, The number of rebuilt and expanded airports also continued to grow rapidly. [0003] And frequent take-offs and landings are also increasing the load on the asphalt pavement of the airport. Therefore, more and more attention h...
