Analysis Of Road Damage Using Pavement Condition Index (PCI) And Surface Distress Index (SDI) Methods on The Tambakboyo Highway Section, Lamongan Regency

Abstract

Roads as one of the transportation infrastructures and part of the national transportation system have an important role, especially in supporting the economic, social, cultural and environmental sectors. Realizing the importance of the role of highway infrastructure in national development, including regional development, especially in Lamongan Regency, the stages of road planning, implementation and maintenance activities should be handled properly so that the road service capacity can meet the expectations of road users. The purpose of this study was to determine the condition of the road from the type and level of damage on the Tambakboyo Highway, Lamongan Regency. The methods used in this study were the Pavement Condition Index (PCI) method and the Surface Distress Index (SDI) method. Tambakboyo Highway STA 0+000 – 1+400 with a width of 5 meters is divided into 7 segments with a road length each segment of 200 meters. 4 types of damage were found, namely grain detachment, longitudinal/transverse cracks, holes, and patches with the results of the percentage of PCI damage values categorized as Satisfactory because they showed an average value of 79.86 with a proposed repair in the form of Patches. Meanwhile, the SDI value is categorized as Good because it shows an average value of 32.14 with a proposed repair in the form of Routine Maintenance. In the analysis of the repair budget plan, the cost was obtained at Rp. 5,440,000, the largest cost component is in STA 0+600 – 0+800 according to the pavement condition that requires patching and periodic maintenance.
