Abstract
Abstract Road defects often occur at signalised intersections, leading to reduced vehicle speeds and traffic congestion. Road damage has a direct impact on increasing fuel consumption and vehicle emissions. So a benchmark is needed to assess the condition of the pavement, one of which is the PCI (Pavement Condition Index) method. PCI is the level of pavement surface condition. If there is known damage, it is necessary to make efforts to improve the pavement structure. One of them is with the help of SPDM (Shell Pavement Design Method) software, which is software that functions to determine the performance of asphalt in the form of pavement thickness. The results showed road damage at a signalled intersection using the PCI method, so that recommendations for handling the damage can be found. From these recommendations, road structure improvements are carried out with overlays analysed using the SPDM application. The overlay thickness is obtained by subtracting the SPDM design thickness and the total design thickness of the flexible layer. The result is the overlay thickness on Tentara Pelajar Road 49 mm, West Diponegoro Road 75 mm, and East Diponegoro Road 74 mm. Improvements to the pavement structure at signalised intersections can reduce vehicle gas emissions.
