Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with specific embodiments.

[0032] 1 Features and requirements of field test on highway runway

[0033] The road runway is not only different from Yongbei Airport, but also different from the highway. Because of its obvious use requirements and characteristics, its on-site test requirements are also different. In order to comprehensively and accurately grasp the surface function and carrying capacity of the highway runway and provide reliable technical parameters for evaluating the performance of the road surface, it is necessary to analyze and study the characteristics and requirements of the highway runway field test.

[0034] 1.1 Vehicle traffic requirements, traffic cannot be interrupted

[0035] Most of the roads and runways in our country are built on expressways. Not only are there large trucks, but also small cars. Generally, the routes on which they are located have the characteristics of heavy tra...

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...
