A Study of the Semi-Perpetual Pavement Performance in Queensland

open access: yes, 2012
This paper presents the performance characteristics of a long-term pavement performance (LTPP) site with pavement constructed with semi perpetual pavements. The design life of the perpetual pavement is normally specified as 40 years. To achieve a 40 year

Finite element analysis of bearing capacity and cracking failure in semi-flexible pavement materials

open access: yesMaterials Research Express
Semi-flexible pavement (SFP) materials are known for their outstanding rutting resistance; however, their applications to new pavements are limited due to uncertainties in their structural bearing capacity and cracking behavior.

Causes of rutting in flexible and semi-rigid test sections after 14 years of service

open access: yes, 2018
Rutting is a major distress and is commonly targeted in design-build contracts as a key requirement, but at the same time, contemporary design methods usually provide scarce information on evolution in absolute terms.
