Abstract:
Perpetual pavements are in existence since 1960 with satisfactory performance. These
pavements are usually designed based on the endurance limit property of bound pavement
materials, which is the critical stress or strain, below which the material can be subjected
to an infinite number of load repetitions without causing fatigue failure. The endurance
limit value significantly affects the design of a perpetual pavement. Various methods have
been proposed for determination of endurance limits for different types of bound pavement
materials. This paper presents a comprehensive review of such methods and suggests
the suitable method to be adopted for the determination of endurance limit based on
bound material type after critical discussions.
