Abstract
Increasing loads have put great responsibilities on engineers to either improve or develop the methods used in design of rigid pavement. This pavement consists of a number of adjacent concrete slabs either in longitudinal or transverse direction. These slabs are linked together by a group of dowel bars. This type of pavements is generally used in highways and airports in case of high traffic loads or in case of subgrade weakness. The concrete slabs are cast directly on the subgrade or on the subbase layer above the subgrade layer due to the requirements of design. Some of the advantages of rigid pavements are low cost of maintenance, high performance, and durability Description of the three dimensional finite element code, FEAFAA, that developed by Federal Aviation Administration is introduced. The FEAFAA code capabilities and procedures to analyze the rigid pavement is presented The FEAFAA code limitations or drawbacks are also presented Using the three dimensional finite element code, FEAFAA, a parametric
