Comparative Analysis of Concrete Road Pavement Improvement and Asphalt Road Pavement Reviewed from Cost and Time Aspects on the Bringkang – Lampah Road Section, Gresik Regency

Abstract

The southern region of Gresik Regency has experienced significant development in the residential, agricultural, and industrial sectors, necessitating improvements in road infrastructure. The Bringkang–Lampah road segment serves as a vital link between agricultural areas, residential zones, and local economic centers. The current damaged condition of the road disrupts community mobility. Therefore, a comparative analysis between rigid pavement (concrete) and flexible pavement (asphalt) is required from both technical and economic perspectives. The methods used are the Manual Desain Perkerasan Jalan (MDPJ 2017) for flexible pavement and Pd T-14-2003 for rigid pavement. Data were obtained through field surveys, Dynamic Cone Penetrometer (DCP) tests, and traffic volume analysis for 20- and 40-year projections. The calculations for pavement thickness and cost were conducted by considering the reuse of existing pavement structures for efficiency. Construction time was also evaluated as a key variable in assessing the effectiveness of each pavement type. The study found that flexible pavement requires a cost of Rp 15,382,772,000 with a design life of 20 years, while rigid pavement requires Rp 18,093,230,000 with a 40-year design life. Although the initial cost of rigid pavement is 17.61% higher, it has twice the service life and better resistance to heavy traffic. In terms of construction time, flexible pavement requires 56 days, while rigid pavement takes 72 days. Therefore, it can be concluded that rigid pavement is more economical in the long term for roads with high traffic loads and longer design life.
