Abstract
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 for the whole of life of a road pavement, under real operational conditions. Pavement Design requires an in depth understanding of the properties of the component materials. Hot Mix Asphalt (HMA) is the most important component of a pavement since it provides the strength and flexibility to support the loads it is intended to carry; waterproofing of the unbound components and a smooth, safe riding surface for all users. Hot Mix Asphalt is one of the most complex materials that an engineer can engage, it is brittle at low temperatures and will flow at high temperatures, The performance of HMA depends of the pavement temperature and the rate and magnitude of loading, all of which will vary many times in any 24 hours, yet we assume one value for "stiffness" through the resilient modulus for perhaps the next 20 years. This paper examines how the Dynamic Modulus (|E*| can be developed in the Laboratory as a Master Curve, coupled with temperature gradient parameters to provide characterization for Dynamic Modulus that can be used in a simulation method to determine the Number of Cycles to fatigue failure for a pavement lifetime spectrum of environment and traffic
