Accelerated loading tests on applicability of large stone asphalt concretes in surface course for airports

This study evaluated the applicability of using large stone asphalt concrete for the surface course of airport pavements. A static loading test, FWD test and accelerated loading test were performed on two experimental pavement sections located at the laboratories of the National Institute for Land and Infrastructure Management, Japan. In one section, the surface and binder courses were constructed using conventional asphalt concrete, while in the other section large stone asphalt concrete was used. During the static loading test, the load was gradually increased in 10 kN increments up to 282 kN and the surface displacements were measured at 6 different points. In the FWD test, 4 different loading levels, i.e. 100 kN, 150 kN, 200 kN, and 250 kN were applied on the pavement surface and time series load and surface deflections were measured at 7 different points. A total of 10,000 load repetitions equivalent to the wheel loading of B747-400 were also applied on these test sections. During this test, dynamic vertical displacement, dynamic earth pressure as well as temperature at different cross sectional levels were measured. Transverse surface profiles of the test section were measured after every specified number of load repetitions. The results indicated that large stone asphalt concrete might reduce the permanent deformation of pavement as compared to conventional asphalt concrete. This paper discusses the results and implications.
