Abstract

Permanent deformation of asphalt mixes is caused as a result of several parameters, including; asphalt mix characteristics, climatic conditions, and traffic loading extent and configuration. For evaluating this distress mode, international institutions and standard codes of practices suggest different processes and testing methods. However, each of these investigates rutting resistance of asphalt mixes at specific conditions. The aim of this research was to investigate the effects of different loading configurations on Hot Mix Asphalt (HMA) in laboratory, applying Repeated Load Permanent Deformation (RLPD) testing method. With this purpose, various loading configuration and load durations and rest periods were applied. In order to simulate the impacts of both light and heavy weight traffic loading on permanent deformation resistance of mixes, two different stress levels of low and high extents were applied in RLPD testing. Based on the findings of this research, it resulted that asphalt mixes under low stress level (which corresponds with light weight loading traffic) in RLPD testing, do not get to “Flow Number” values. In addition, it resulted that performance characteristics of asphalt mixes cannot properly be evaluated applying one loading condition only. Among the various testing parameters, it resulted that “Flow Number” is the best indicator of resistance of asphalt mixes against permanent deformation.
