Analysis of Cost Estimation and Road Surface Assessment of Kemlagi - Berat Kulon Road Section of Mojokerto District Using SDI Method

The road surface conditions on the Kemlagi–Beratkulon section in Mojokerto Regency were assessed, as it is a vital route linking Mojokerto and Gresik Regencies for transportation and economic activities. This research aimed to evaluate the road surface conditions and identify the severity of damage using the Surface Distress Index (SDI) method. The study employed a field survey method, dividing the road into 100-meter segments. Visual observations were used to measure crack area, crack width, number of potholes, and rutting depth. The results showed SDI values ranging from 165 to 285, with the highest value recorded at STA 2+500–2+700, indicating "HEAVY DAMAGE" in these areas. These findings highlight the need for immediate reconstruction to restore road functionality and prevent further degradation. The study underscores the SDI method’s effectiveness in providing a systematic evaluation of road conditions, which aids in prioritizing maintenance, resource allocation, and cost estimation. The research also implies that integrating the SDI method with advanced technological tools could lead to more accurate and proactive monitoring of road conditions, enhancing sustainable road management strategies.
