Abstract

Civil Engineering transfer function layer temperature design simulation field sampling
Pavement Management embraces the full range of engineering activities (Design, Construction, Operation, Maintenance and Renewal), throughout the life cycle. Over the past 4 years, The Queensland Pavement Centre at the University of the Sunshine Coast, Australia, has been studying the various parameters that influence pavement behaviour and those parameters that impact the whole of life of a road pavement under real operational conditions. By 2015 five sites have been installed in operational pavements, designed to monitor the performance of critical parameters as a function of material properties, climatic changes and the complete spectrum of traffic usage. One site (Sippy Downs Drive - East) has been operational for over 1000 days. This paper is based on the findings from that study. The paper will address a design aspect of Pavement Management, in particular the critical strains as measured in the subject pavement every minute of every day for the past two years and demonstrate how the performance parameters can be utilised in a simulation method to predict whole of life performance based on operational data, obtained from real life, rather than assumed parameters. The configuration of other sites and a test suite for installation and analysis are recommended.
