The Use of Stress Absorbed Membrane Interlayer (SAMI) to Reduce Reflection Crack on Road Pavement

Reflection crack is one of main problems on road pavement in Indonesia. Reflection crack is a crack will reflect through an overlay placed on top of it. One of  ethods used in improvement of reflection crack resistance is Stress Absorbed Interlayer (SAMI). The purpose of this study is to evaluate the SAMI layer with different conditions. The SAMI layer systems used in this research were one layer and two layer systems. The samples of 30 cm x 30cm x 5 cm size were prepared using Whell Tracking Compacter. The SAMI had a significant effect on fatigue crack performance, which bituminous mix using SAMI exhibited better in reducing reflection crack compared to conventional bituminous mix. The use of the SAMI with one layer system and modified bitumen with 2% SBS showed the best performance in term of the fatigue crack.
