Abstract

The Gampang-Peti'in road in Lamongan Regency plays a strategic role as a main route supporting the agricultural, trade, and public service sectors. However, the significantly damaged road conditions have increased logistics costs, delayed goods distribution, and decreased community productivity. This study aims to analyze the total number of commercial vehicle axles traversing this road and determine the required pavement dimensions for both rigid and flexible pavement construction. The method used is pavement design calculations based on the Cement Concrete Road Pavement Planning Guidelines Pd T-14-2003, taking into account average daily traffic (LHR) data, vehicle axle load data, and subgrade soil (CBR) test results.

The results indicate that the total number of commercial vehicle axles on the Gampang-Peti'in road section reaches 1,904 axles, with a JSKN value of 42,206,965.54. Based on the calculation results, the recommended rigid pavement is a concrete road with a design width of 6.00 m, a concrete slab thickness of 20 cm, and a class A base layer of 15 cm. Meanwhile, for flexible pavement, a layered structure is required according to the Pd T-14-2003 standard with a thickness adjusted to the subgrade and traffic conditions. This study emphasizes the importance of road reconstruction with a design that meets technical standards to support the sustainability of transportation functions, improve logistics efficiency, and encourage local economic growth.
