Study of Road Surface Damage due to Rainwater Puddles using the Pavement Condition Index

Abstract

Damage to the road surface will cause many losses that users can feel directly. One of the factors that influence the damage is waterlogging. In Mataram City, several roads experience inundation and water runoff when it rains, such as Jalan Swasembada Kekalik and Jalan Kesra Raya Perumnas. The impact on road construction is a change in the shape of the road surface layer, which causes road service performance to decline. So, it needs to be analyzed to determine the damage to the pavement structure in several segments, both flooded and not. The method used to carry out road damage analysis is the method (Pavement Condition Index) PCI. Surveying road conditions in the field collected data. The PCI value is obtained after calculating the parameters, namely: density, deduct value (DV), total deduct value (TDV), and corrected deduct value (CDV). The results showed that the types and average values of damage to Jalan Swasembada Kekalik were: subsidence (6.22%), edge cracks (3.22%), vertical downhill road edges (8.22%), patches (4.25 %), holes (1%), grain release (27.33%). The average value of the Pavement Condition Index (PCI) for each segment is 36.33%, which is at a lousy level (Poor). In comparison, on Jalan Kesra Raya Perumnas, the PCI value is 82.5%, which is at a reasonable level (Good) evidence that the inundated section has a worse condition than the unflooded section is seen in the Jalan Swasembada Kekalik section, where the inundated area has a poor to poor condition. In contrast, the unflooded team has a very good to perfect condition. For the Jalan Kesra Raya Perumnas section, although in flooded areas, the road conditions are less than those that are not flooded, overall, the roads are in good to perfect condition. By looking at the conditions on each lane, it is necessary to deal damage to several road segments immediately to have a decent performance in serving traffic.
