Traffic loading and environmental effects on asphalt pavement rutting

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 out the separate effects of these two factors on asphalt pavement rutting. It is believed that this will lead to better modeling of pavement deterioration by clearly understanding and treating the two factors as separate entities. Pavement age is used to represent the cyclic effect of environmental forces. A methodology was devised to separate the two effects and analysis was carried out. Results show how each of these factors influence pavement rutting and provide an understanding of the influence of some of pavement parameters on pavement rutting.
