In order to study the behavior of concrete pavement under cyclic loads, the static loading test and the cyclic loading test with the full scale concrete pavement were carried out at the Public Works Research Institute (PWRI) of the Ministry of Construction in 1997. In this study, the reduction of the base course reaction modulus (k value) with cyclic loads and its effect on the fatigue failure of a concrete slab were investigated. The plate FEM program was used for analysis of mechanical behaviors in the loading test, and two types of fatigue curve were utilized for the fatigue analysis of the concrete slab. The result showed that the reduction of k value with the permanent deformation of base course surface accelerated the fatigue failure of the concrete.
