Analisis Perbandingan Desain Mekanistik-Empiris Struktur Perkerasan Lentur dengan Pemodelan Elastik dan Viskoelastik : Studi Kasus pada Ruas Jalan Milir-Sentolo

Abstract

Roads are land transportation infrastructure that plays an important role in the transportation sector, especially for the continuity of the distribution of goods and services as well as people. The existence of a good and useful transportation system is one of the important requirements for the development and improving the welfare of the community. Milir-Sentolo road is one of the routes that connects DIY Province with Central Java Province and supports the development of the Kulon Progo Regency area. In addition to supporting the economic sector of the Kulon Progo District, this road segment is also an access to Kulon Progo Airport from Yogyakarta Province. In designing the pavement structure of Milir-Sentolo road, data is collected from Satuan Kerja Pelaksana Jalan Nasional (P2JN). In this research, the pavement thickness was analyzed using the mechanistic empirical method namely KENPAVE program with elastic and viscoelastic modeling. After analyzing the KENPAVE program with elastic and viscoelastic modeling using the existing pavement AC-WC 4 cm, AC-BC 6 cm, AC-Base 20 cm and LPA class A 30 cm, the response of the axle load repetitions was 154,797,390 ESAL until permanent deformation damage happened with elastic model and 85,378,748 ESAL until permanent deformation damage happened with viscoelastic model. From the repetition of axle loads, the service life of the existing flexible pavement is up to 21 years until it’s damaged by permanent deformation with the elastic modeling and for the viscoelastic modeling is only able to withstand up to 14 years until it’s damaged by permanent deformation.
