Thickness of Overlay Design with CESA5 Implementation and Benkelman Beam Deflection Through Manual Method of Road Pavement Design 2024 on Pahlawan Street, Sidoarjo Regency

Abstract

Jalan Pahlawan - Sidoarjo is a collector road with a Type 4/2 D Road with a length of 3.3 km located in Sidoarjo Regency. The road is a connecting road with a fairly high intensity of activity, which causes the quality of the road pavement to weaken. Road damage that occurs such as cracking, peeling of aggregate grains, and holes. So it is necessary to plan an overlay to increase the strength of the structure and avoid more severe damage by traffic loads. This study uses the 2024 Pavement Design Manual (MDP) method with the CESA5 approach and deflection from Benkelman Beam. Secondary data used in the form of Benkelman Beam (BB) deflection and average daily traffic data (LHR) obtained from the PU Bina Marga Service with the results of CESA4 values of 16,760,006 ESA and CESA5 of 19,990,025 ESA. The results show that the thickness of the overlay with a design life of 20 years based on the maximum deflection D0 0.376 is 5 cm, and the thickness based on the deflection curve D200 0.239 mm is 12 cm. From the analysis results, the overlay thickness is taken as 12 cm, because with a thickness of 12 cm it is expected to withstand damage due to fatigue cracks before the planned age caused by the load of passing vehicles, so that road users can operate safely and comfortably on Jalan Pahlawan - Sidoarjo.
