Performance Test And Evaluation Of Airfield Area In Harbin Airport

Harbin Taiping international airport is the international airport with the largest passenger throughput in northeast China,with 185 domestic and international routes and 109 navigable cities.It is also an important hub airport for China to radiate important domestic cities and connect Russia,Japan,South Korea and other neighboring countries,as well as major European and American countries.In recent years,with the rapid economic growth,airport passenger throughput,cargo and mail transportation,and airport run way road aircraft takeoff and landing times increase year by year,resulting in aircraft to the use of apron road more frequently,for the normal use of airport apron road has brought a great test.The current run way of Harbin Taiping international airport was paved with asphalt road in 2001.In order to ensure the security of transaction aircraft operation,this study conducted in Harbin airport airfield pavement pavement damage condition of comprehensive investigation and evaluation work,including the roughness test,deflection test,core sampling and asphalt concrete test,water seepage test,ground penetrating radar(GPR),cement concrete core sample test project,and based on the test results,the functional and structural road in road is used to evaluate the apron road.Through the analysis of test results,it can be concluded that the test r esults of pavement smoothness,water seepage coefficient and other indicators in the flight area are good,and the performance of pavement correlation is good.However,some areas have potential damage,and the asphalt pavement performance in the old runway area is declining,which is not conducive to the normal use of the apron road.After testing evaluation to determine the different regions of the new bulletin PCN value,and combined with relevant data,using the road remaining service life prediction model,predicting the remaining service life of the roads,for the different regions targeted to carry out the renovation of different depth,the airfield pavement operation scheme and overhaul plan,provides the theoretical basis for effectively.
