Effect of Repeated Traffic Loads on Most Significant Distresses of Flexible Pavement

Early fatigue and rutting are among the most common types of road damage due to their main relationship with pavement performance. These damages occur excessive loads on axles vehicles or improper design mixture in addition traditional methods used paving designs. Therefore, these premature must be avoided for proper performance service road. In order overcome some weaknesses, mechanical-empirical techniques using software like ABAQUS program essential. This determines exact stresses, strains, displacement asphalt pavement, which is then predict failures. HMA layers behave viscoelastic materials actual field conditions, temperature variations loading period influence mechanical response. study aims investigate software's problem-simulation capabilities compare findings experimental work approach (E-M) valuable features during change optimize constructions. The results highlighted significance impact that increased changes might have life flexible flexible-viscous layers, where decreases increasing applied surface, reduces 50% age when twice standard load. At same time, both vertical stress percentage increase Temperature increases also result higher tensile compressive strain values, an cost cycle. Therefore its future maintenance requirements verified.
