Traffic Volumes Test of Airport Runway

Currently, airport pavement design only considers the different horizontal standard deviation at the end and the middle of the runway, which had ignored the longitudinal distribution of airport runway traffic volume (ARTV). Especially for short take-off and landing aircraft, the take-off and landing distribution are not full of the whole runway. In allusion to the characteristics of ARTV, this paper developed a test system for the wheel track distribution and conducted a test of a short take-off and landing aircraft. Based on the statistics and analysis of test results, the horizontal and longitudinal distribution statistical laws of ARTV were obtained. At last, the longitudinal passage factor was proposed, and the planar distribution model was established to evaluate the ARTV at each point of the runway. By comparison with current design specifications, it is indicated that the pavement thickness will be designed more conservative without considering the planar distribution of traffic volumes.
