Highway airplane runway surface use performance testing method based on uninterrupted traffic

Abstract

The invention discloses a highway airplane runway surface use performance testing method based on uninterrupted traffic. A to-be-tested section is closed, and vehicles are guided to drive in a decelerated way. A laser roughness measuring instrument is used to measure the roughness of the section. A friction coefficient testing vehicle is used to measure the friction coefficient of the section. A falling weight deflectometer is used to measure the deflection of the section. A three-meter ruler is used measure the roughness of the section. A pendulum friction meter is used to measure the friction coefficient. A pavement structure depth testing instrument is used to measure the structure depth of the pavement. A bearing plate is used to measure the deflection curve of the pavement. A drilled core sampling device is used to measure the thickness of the pavement, and is used to carry out related indoor tests. Appearance inspection is carried out manually, and a pavement damage condition is inspected. The highway airplane runway surface use performance testing method is advantageous in that two lanes of an upstream line and a downstream line are closed, and safety measures are taken, and the driving speeds of the vehicles are limited, and a decelerated passing way is adopted, and therefore space is provided for the highway runway on-site testing, and the traffic is not affected substantially.

Description

Technical field [0001] The invention belongs to the technical field of highway runway construction, and relates to a method for testing the use performance of a highway airstrip surface based on uninterrupted traffic. Background technique [0002] The road runway is an important part of the airport system and can provide aircraft with landing sites in emergency situations. Because it has the advantages of small area, fast construction speed and good concealment performance, my country has also constructed or rebuilt many road runways in the construction of highways (high-speed) simultaneously. [0003] The road runway is a large open-air layered structure. In the long-term use process, in addition to the load of the car, the road surface must also withstand various natural environmental factors such as temperature, humidity, sunlight, and ultraviolet rays. Its performance A certain degree of change is bound to occur. With the development of my country's transportation industry, t...

Problems solved by technology

[0011] The purpose of the present invention is to provide a road surface performance test method based on uninterrupted traffic. Expressways not only bring trouble and inconvenience to vehicle traffic and transportation, but also cause losses to the economic benefits of the road section, resulting in the inability to judge whether the road surface can meet the needs of combat aircraft after a period of use of vehicles
