THE LOSS OF LOAD--TRANSFER CAPACITY AT JOINTS OF AIRFIELD CONCRETE PAVEMENTS UNDER REPETITIVE LOAD

Joints are a weak part of the airport runway concrete pavement structural system. When joints are in good working order, they have a fairly high capacity of load transfer. Generally, the load transfer capacity decreases with an increase in the number of repetition of loads, which leads to a loss in the design bearing capacity of pavement. This process is termed the loss of load transfer capacity of joint, which can result in an increase of edge stress, cracks, and finally, loss of support. It is of great importance to study the loss of load--transfer capacity for several joint types under repetitive loads in order to improve the performance and durability of concrete pavement of airport runways. For this purpose, the Transportation Research Institute of Southeast University (Nanjing) and the Guangzhou Branch of the China construction company created an experimental pavement with 5 types of joints on a circular track road test platform built in a laboratory of the University. The Falling Weight Deflectometer is used to measure the loss of load transfer capacity of joints under loads. Through testing and analysis, the relationships of the loss of load transfer capacity of joints and the edge displacement with the loading repetition numbers were determined. The analysis also indicates that the dowelled joint and engaged joint are the best joint types among the 5 studied.
