THE SEPARATE EFFECTS OF TRAFFIC LOADING AND ENVIRONMENT ON RUTTING AND CRACKING TRENDS OF ASPHALT PAVEMENTS

Road pavements deteriorate with traffic loading and environment but the separate effects of these factors are not yet well defined especially with age or environment. This paper aims at finding the separate effects of these two factors on asphalt pavement rutting and cracking. It is believed that this will lead to better modeling of pavement deterioration by clearly understanding and treating the two factors as separate entities. A methodology was devised to separate the two effects, in which pavement age is used to represent the cyclic effect of environmental forces, and analysis was carried out. Results show how each of these factors influence pavement rutting and cracking and provide a further understanding of the influence of some pavement parameters on pavement rutting.
