Title: Performance based specifications for unbound granular pavements: procedures for demonstrating achievement of design life
Abstract: Transit New Zealands pavement maintenance specifications include Operational Performance Measures for rehabilitation treatments. One of these requires that the treatment is constructed so that post-construction materials testing and falling weight deflectometer (FWD) testing confirm achievement of the design life. The Transit NZ Supplement to the Austroads Guide, has provided one procedure that may be used, provided deflection testing is carried out both before and after rehabilitation. However, often only post-construction testing is available and the procedures which maintenance contractors should follow to demonstrate achievement, are less well defined. This article provides alternative methods, depending on test data available, with suitable rationale for application. Rehabilitation treatments are addressed primarily. In some cases, new pavement construction can be assessed similarly but with limitations. (a) For the covering entry of this conference, please see ITRD abstract no. E214098.
