Probabilistic Seismic Hazard Analysis on Pavement Failure Restoration; Case Study of Sorong–Makbon Road

The Sorong–MakbonSorong–Makbon Corridor is one of the key routes connecting Sorong to other sections West Papua region in Indonesia. Throughout Sorong–Makbon Corridor, roads and slopes often sustain damage. When landslides reach road shoulder destroy pavement, they prevent access road. In addition influence surface water runoff, there are indications that earthquakes contribute ineffectiveness previous design. This seems be accurate since author has seen typical movement avalanches. Using Probabilistic Seismic Hazard Analysis (PSHA) approach, earthquake’s effects on this corridor were mapped out. With use Indonesian earthquake data library, Matlab-Zmap Program, Spectrum Response, history was analysed determine their velocity. analysis reveals an acceleration value between 1.2 1.5 G. prior design did not account for a quake magnitude. study, correctly identified seismic impact could sent back into simulation more adequately repair restore
