Semi-flexible pavement is the combination between the cementitious grouts rigidity and bituminous material flexibility and it was produced from the best qualities of bituminous and concrete component. The main purpose of this study is to concentrate on the design and properties of bituminous mixture to be utilized in the semi-flexible pavement application. The open graded bituminous skeleton was prepared to achieve a compacted porosity between 25% and 30% of the total volume and at the same time maintaining adequate bitumen coating on the aggregates particles. In order to investigate the properties of open graded skeleton, a range of performance and deformation tests were conducted. The tests are porosity, indirect tensile stiffness modulus, compressive strength and cantabro test. The results obtained were compared with porous asphalt skeleton by Zoorob et al. (2002).
