Abstract

Roads are a mirror of civilization and the development of people. Road network services and efficiency represent the economic face and source of the country's growth. The road network in Iraq in general and in the Hillah city, in particular, is exposed to severe traffic and environmental conditions,as the asphalt pavement is affected by axle loads in terms of weights and repetitions, as well as illegal loads. This study aims to evaluate the effect of axle loads on asphalt layers and suggest a designcommensurate with axle loads used for the road. The study is based upon an intensive traffic study, where it classifies traffic volumes based on peak hour volume, the studyused the concept of Equivalent Single Axle Load according to the AASHTO 1993design method, to raise the level of service of road, safety, avoiding waste of human and financial, and maintenance work decrease.The study concluded the thickness of asphalt and subbase layers is (33, 30) cm respectivelyas well as compared them with the pavement layers implemented. So recommends set standards for approving maintenance types by specialized departments with documentation and installing weighing stations to control the effects of axle load on the road.
