Design of the strong and durable of flexible pavement on road segment with the heavy traffic and overloads

The arterial road sections are generally heavy vehicles that tend to exceed the standard load so that the existing pavement surface is not able to survive according to the design life despite using modified asphalt. This has been proven by the occurrence of a heavy damage in a relatively short time on most primary arterial roads in Indonesia. In this paper, the method of implementation and criteria for the construction of pavement layers with a certain thickness has been prepared according to the planning standard for the volume of excessive vehicle loads and taking into account extreme weather conditions in Indonesia. There are three (3) main things in this paper that become an important factor in determining the structure of a solid and durable; they are the sand as layer controlling deflection (stabilizer), the weight of the Vibratory roller more than 25 tons to achieve maximum of compaction energy for base course, and a single-layer of AC-Base as a surface layer as anticipation of rutting and bleeding. Single overlays in each layer are rigidly constraining overall construction, while the sand layer can neutralize deflection due to overload and force due to the vertical force of subgrade, so that these three factors are energy deposits in the pavement construction that will work when an increase in load exceeds the standard.
