چکیده مقاله:
Although most procedures of pavement design of ASSHTO and RStO 01 depend in general, on the design parameters such as traffic load, bearing capacity of soil or subgrade, highway material characteristics and environmental conditions, they differ to some extent in the details of the calculation methods. First, the research indicated the main steps of RStO 01 pavement design procedure including determining the volume of traffic loads, construction classes and thickness of different layers and parallel to that the required degree of compaction and bearing capacity of different layers were investigated. Then it highlighted the relevant differences between AASHTO and RStO by redesigning a section of a defect asphalt pavement in Idaho (USA), primarily designed based on AASHTO 1993, according to German catalogue (RStO 01).The Idea of selecting the state of Idaho was based on similarity of some peripheral factors affecting the pavement design such as annual average precipitation and temperature fluctuation in Idaho with state of Bayern and specially city of München in Germany where RStO 01 was adopted. In other words the approach was tried to make the peripheral conditions equal in order to reach a comparable situation
