Problems solved by technology

On the other hand, during the long-term use of the surface asphalt mixture, the performance of the asphalt mixture is degraded under the long-term combined action of aircraft dynamic and static loads and environmental factors, resulting in a certain number of irregular cracks on the pavement and longitudinal and transverse cracks

preparation example 1

[0033] Heat 100kg of base asphalt to 170°C, add 2kg of SBS resin, swell at 170°C for 0.5 hours, then heat up to 175°C and grind with a colloid mill, then add 1kg of rubber softening oil; control the temperature and stir at 180°C for 2 hours to reduce After the temperature reaches 170°C, add 0.005kg of stabilizer and stir for 1 hour.

preparation example 2

[0035] Heat 100kg of base asphalt to 173°C, add 3kg of SBS resin, swell at 173°C for 1 hour, then heat up to 178°C and use a colloid mill to grind, then add 3kg of rubber softening oil; control the temperature at 183°C and stir for 2.5 hours to reduce After the temperature reached 173°C, 0.01kg of stabilizer was added and stirred for 1.5h.

preparation example 3

[0037] Heat 100kg of base asphalt to 175°C, add 5kg of SBS resin, swell at 175°C for 1 hour, then heat up to 180°C and use a colloid mill to grind, then add 6kg of rubber softening oil; control the temperature and stir at 85°C for 3 hours, reduce After the temperature reaches 175°C, add 0.02kg of stabilizer and stir for 2 hours.

Abstract

The invention discloses a construction process of an airport runway, which belongs to the field of the airport construction. The construction process comprises the following steps: removing the surface plant soil, flattening the field, tamping the soil foundation, constructing a liner layer, constructing a basic layer, and constructing a surface layer. The construction process not only can solve the problems of foundation settlement, frost heaving and salt heaving caused by the water permeation, but also can improve the overall performance of the foundation, and can improve the rigidness of the foundation, so that the dynamic response of the pavement surface layer under the dynamic load effect of an airplane can be improved, and the disease problem of the airport pavement can be fundamentally solved.

Description

technical field [0001] The invention relates to the field of airport construction, more specifically, it relates to a construction technique for an airport runway. Background technique [0002] The airport pavement is a one- or multi-layer artificial structure paved with road-building materials on the top of the natural soil foundation and base, which bears the wheel load of the aircraft, high-temperature and high-speed jet flow, and cold and heat, dry and wet, freeze-thaw, etc. and other natural factors, including runways, taxiways, passenger aprons, maintenance aprons, cargo aircraft aprons, parking aprons, etc. The design of airport pavement requires that the soil foundation must be dense, uniform, and stable, and meet the requirements of bearing aircraft loads and the self-weight of the pavement structure. Because the airport pavement is subject to dynamic loads such as aircraft test vibration, taxiing, and landing impact, it puts forward more requirements than ordinary...
