Abstract

Abstract:

The effective width of aircraft tire loads at the top of subgrade has a significant effect on calculating the load repetitions in designing an airport asphalt pavement. The relationship between the effective width of aircraft tire loads and subgrade strength, equivalent surface thickness is researched basing on a single wheel by ANSYS. For a complex main gear, multiple tires will lead to load interaction. How to approach the effect of load interaction on effective width of tire loads of complex main gear is also discussed. According to these analyses, calculation method of tire loads‘effective width of complex main gear is achieved.

Key words: asphalt pavement, load repetitions, effective width, gear
