Deformation behavior of flexible pavements by finite element simulation

Flexible pavement is usually designed based on certain axle load limits and climatic conditions. The Iraqi code has specified per each type that should not be exceeded. However, many trucks violate these by carrying additional weights to decrease the transportation cost. These overweight cause severe deterioration thus reduce its life. authorities generally charges violating a penalty their weights. This could very small compared damage occurring over Also, some may carry huge support, so unloading such suitable solution rather than paying few amounts of money deteriorating pavement. study aims at studying effect increase, variation in moduli, overall It also estimate truck penalized or unloaded. research uses ABAQUS software conditions tensile strains under asphalt concrete (AC) layer compressive above subgrade surface. computed are incorporated fatigue cracking rutting models life for different Results showed unloaded when exceed limits.
