| Abstract | ||||
| The roads need to be repaved are those possessing a lot of damage, rutting causing many problems for vehicles and drivers. Two methods of repaving roads are introduced in this paper. The first method includes constructing two layers of pavement structure above the road directly without removing the old wearing surface of this road. The second includes constructing the same two layers of pavement structure above the road after removing the old wearing surface to the surface of the old base course. The two layers are leveling layer from crushed aggregate and new overlay surfacing layer from asphaltic concrete. The effect of these layers is to reduce the stresses and deflections to permissible limits of old foundation. This piece of paper uses the elastic theory and Excel program to establish an approach for overlaying design of flexible repaved road structure. Using this approach, the designer may be able to determine the suitable thicknesses of pavement layers of overlaying flexible repaved road structure. | ||||
