The natural disaster can happen anytime and cannot be predicted accurately where the disaster will occur. This study aims to identification and disasters level of vulnerability mapping on the road, and to identify the type of road pavement damage with PCI Method which conducted on parangtritis street KM 16,5 – KM 20,5 with STA 21+800 – 25+100. mapping vulnerability of disaster is using arcgis software with four types of disasters which is flood, subsidence, landslide and earthquake and using landscape analysis method. The result of analysis is show that the disaster with the highest vulnerability potential are flood and subsidence, earthquake with medium potential, and landslide with low potential. PCI method based on flood mapping, because this type of disaster really influence the function of the road, so that can have an impact on comfort and safety to the road users. PCI survey analysis along 3,3 KM. The results of the PCI calculation were obtained at an average of 52.54, which means that the road has fair class of damage.
