Abstract: The annual floods that occur at the study site and and the condition of the swamp pavement the cause of the damage, both minor and severe damage will greatly affect. This study aims to determine the type of damage, improve the condition of pavement and provide information on damaged roads and the geotechnical vulnerability index of road damage. The method of the Pavement Condition Index (PCI) used to evaluate the pavement condition based on the typeand the level of the damage an Analytical Hierarchy Process (AHP) process to assess roads and guide the Indonesian disaster manual to obtain an index for geotechnical road damage. To assess the relationship between factors causing damage to modeling of partial least square-structural equation modeling equations. The results showed 44.47% damage type with 83.80 M2 width and damage level of PCI 24 at very poor level occurred on Boulevard road, most difficult from road damage condition 0.204, highest score 6.86 on Mokodompit road and lowest on path of Manunggal with index value 3,00. The interrelationship of the structure-PLS provides the best parameters that directly affect the aspects used with traffic, the Tata modify functions and parameters that do not affect the aspects that create the road network. The results of this study have practical implications as a m eans of identifying the extent of damage to collector roads in municipalities that have swamp areas and unstable groundwater conditions.
