Analysis of Back Defect Method Using Tools benkelman Beam in Planning Layer Thickness Add Flexible Pavement (Overlay)

Abstract

This research is backgrounded by the level of road damage that occurs on the Isimu - Paguyaman road so that the need for handling so that the transportation route runs smoothly. This study aims to analyze and determine the thickness of the overlay layer (overlay) using the 2017 Road Pavement Design Manual (MDP 2017) method with the Benkelman beam test tool, which is carried out on the Isimu - Paguyaman Road section (STA 17 + 100 - STA 18 + 100). Based on the results of the study, the overlay thickness was obtained from the results of traffic volume analysis by taking into account the CESAL value for 10 years of planning age of 11,476,966 ESA 4 for 10 years of planning age of 19,233,188.4 ESA4 and CESAL valueof 5. The difference in the results of calculating the CESAL value is due to the determination of equivalent numbers and different VDF values in each calculation. Overlay thickness based on the method of the 2017 Road Pavement Design Manual obtained a minimum AC-WC thickness of 11.23 cm by using an overlay thickness solution graph based on maximum characteristic deflection.
