Comparative Analysis Of Flexible Pavement Structure Design With Viscoelastic And Elastic Approach On The Sta 10+500 – Sta 11+000 Of Sentolo-Nanggulan-Dekso Road
Abstract
The Sentolo - Nanggulan - Dekso - Klangon road section is an alternative route that
connects Yogyakarta International Airport with the Borobudur Temple area. The section, which has
the status of a provincial road, is included as one of the supporting lines for the Borobudur National
Tourism Strategic Area. The goal of this study was to find wether 2017 Bina Marga method optimum
in holding the vehicle load within the planned timeframe, and to compare the design of existing
pavement structure and the new design to estimate what damage occurred first.
In designing the pavement structure of Sentolo – Nanggulan - Dekso Street, data is
collected from National Road Planning and Supervision of D.I. Yogyakarta 2020. In this research,
the pavement thickness is designed using two Mechanistic - Empirical methods which are Bina
Marga 2017 method with Manual Perkerasan Jalan Nomor 02/M/BM/2017 guidance and supported
by Kenpave program with Viscoelastic and Linier Elastic approaches.
The analysis utilizing Bina Marga 2017 methodology yields the following pavement
alternatives in thickness: AC-WC 4 cm, AC-BC 6 cm, AC-Base 14,5 cm, and A class Base Course
20,5 cm. With the exception of the AC-Base layer and class A Base Course , which is only 20 cm
and 15 cm thick, these values are equal to the pavement's current thickness. After the flexible
pavement alternative's design has been completed using the Kenpave program, axle load repetition
continues for about 34,704,817.14 ESAL with the Linier Elastic approach and for about
33,856,927.47 ESAL with the Viscoelastic approach before permanent deformation occurs. With
respect to that axle road repetition, the service life of a flexible pavement alternative is 35 years for
a viscoelastic method and 36 years for a linier elastic approach. This simulation demonstrates that
an alternative to rigid pavement
