Study on the Performance of Graded Gravel Roadbase in Freeway Asphalt Pavement

Abstract:

The elastic modulus of graded gravel material has a paricular characteristics of nonliner. The objective of this study is to discusses the performance of graded gravel roadbase in freeway pavement using KENLAYER computer program. Asphalt Institute (AI) and Shell design methods have been considered using equivalent standard axle load (ESAL) and spectrum of axle methods of incorporating traffic for the design period. Design life in years is determined using fatigue cracking models and rutting models in KENLAYER computer program, which is feasible in the life forecast of graded gravel roadbase. It is beneficial to graded gravel roadbase′s popularization and application in freeway pavement.
