| dc.description.abstract | Data and information regarding road networks and their supporting
infrastructure are crucial elements in planning the management of road databases.
Medan Amplas Subdistrict in Medan City has a road network comprising national
roads, provincial roads, and city roads, totaling 143.14 km. The study area in this
research focuses on secondary local roads with flexible pavement, spanning 33.12
km. The method used in this study is the Surface Distress Index (SDI) method. SDI
categorizes road conditions into four categories: good, fair, minor damage, and
severe damage. Based on RCS or SKJ 2011, four elements are used to calculate the
SDI value: percentage of cracked area, average crack width, number of potholes,
and average rutting depth from wheel tracks. Researchers then inventoried the road
data using the Geographic Information System (GIS) method with the ArcGIS 10.8
application. The analysis results of road damage levels on secondary local roads
with flexible pavement in Medan Amplas Subdistrict show that 51 road sections are
in good condition (98%), and 1 road section is in fair condition (2%). This indicates
that the secondary local roads in Medan Amplas Subdistrict are generally in good
condition, with only routine maintenance needed at specific points on each road
section. The road conditions of secondary local roads in Medan Amplas Subdistrict,
according to the SDI method, are rated as good, except for the inspection road of
Sungai Denai, which is rated as fair. The inventory of road condition data and basic
data for secondary local roads in Medan Amplas Subdistrict using GIS provides an
overview of road conditions in the form of a road network map. This facilitates
monitoring road conditions and determining the type of maintenance needed.. | en_US |
