Problems solved by technology

[0005] The present invention solves the problem that the existing evaluation method of airport asphalt pavement resistance to high temperature and permanent deformation relies on the evaluation method of road engineering asphalt mixture anti-rutting performance, resulting in low load, single wheel load and load action form in the airport asphalt pavement material test. Based on the actual conditions, a test system and method for testing the high temperature deformation resistance of airport asphalt pavement is proposed

Abstract

The invention relates to a testing system and a testing method, in particular to a testing system and a testing method applied to a testing of the high temperature deformation resistance of an asphalt airport pavement; the invention aims at solving the problem that an asphalt airport pavement material testing is conducted under the conditions of low load and single-wheel load and the condition that a load action form does not meet the practical situation due to the fact that an existing method of evaluating the high temperature permanent deformation resistance of the asphalt airport pavement depends on a method of evaluating the rutting resistance of a highway engineering bituminous mixture. The testing system disclosed by the invention comprises a motor, a motor supporting seat, a main shaft, a plurality of guide pillars, a top fixed plate, a bottom fixed plate, a rubber wheel supporting disk, a charging tray, a supporting plate, a hydraulic cylinder, a pressure sensor, rubber wheels, a plurality of supporting wheels, an upper bearing block, a lower bearing block, a rubber wheel disk connecting sleeve and a bottom plate; the top fixed plate, the bottom fixed plate, the supporting plate and the bottom plate are arranged in parallel from top to bottom in sequence; the guide pillars are evenly distributed. The testing system and the testing method disclosed by the invention are used for the field of road and bridge construction.

Description

technical field [0001] The invention relates to a test system and method, in particular to a test system and method for testing the anti-high temperature deformation performance of airport asphalt pavement, belonging to the field of road and bridge construction. Background technique [0002] The occurrence of wheel tracks on the airport pavement directly affects the safe operation of the airport. In 2011, there were many safety accidents at the Capital International Airport that caused the aircraft to be trapped on the runway due to the high temperature deformation of the airport pavement. Major hidden dangers have also caused adverse social impacts. The appearance of wheel ruts greatly increases the possibility of damage to aircraft tires, turbine engines and airframes, and also increases the probability of aircraft deviating from the track when taxiing. Studies have shown that water accumulation in the wheel ruts in rainy days can lead to insufficient skid resistance of t...
