Ded Reconstruction of Jalan Nginggasrembyong Keprabon

Abstract

Roads are vital infrastructure that support public mobility and the distribution of goods and services. However, increasing traffic loads and the growth in the number of vehicles often lead to a decline in road quality characterized by cracks, deformation, and reduced user comfort. This research takes a case study on the Nginggasrembyong–Keprabon road section, Gresik Regency, which has a strategic role but has experienced significant damage requiring complete reconstruction. The research methods include an average daily traffic (LHR) survey, soil bearing capacity tests using a Dynamic Cone Penetrometer (DCP) and California Bearing Ratio (CBR) values. Data were analyzed using pavement design methods according to Bina Marga guidelines, by comparing two alternatives, namely rigid pavement (cement concrete) and flexible pavement (asphalt). The analysis results show that although the initial cost of rigid pavement is higher than flexible pavement, its longer design life and low maintenance requirements make it more efficient and sustainable in the long term. In addition, rigid pavement is more resistant to heavy vehicle loads and extreme environmental conditions. Therefore, the use of rigid pavement is recommended as a reconstruction solution for the Nginggasrembyong–Keprabon road section to support smooth transportation, reduce vehicle operating costs, and encourage socio-economic growth in the surrounding community.
