EVALUASI KERUSAKAN JALAN DAN KINERJA JALAN MENGGUNAKAN PROGRAM KENPAVE DENGAN PERMODELAN ELASTIK DAN VISKOELASTIK PADA RUAS JALAN KLANGON TEMPEL YOGYAKARTA

Abstract

Klangon - Tempel Road is one of the provincial roads in Sleman Regency,
Yogyakarta. The majority of vehicles that pass through this road are heavy vehicles
from Semarang to Yogyakarta, including the Jogja - Bawen toll road construction
project vehicles. The high traffic load is not matched by good road quality, causing
damage to the pavement structure. This study aims to determine the condition of the
pavement and provide alternative pavement designs that can withstand traffic loads
well. Evaluation of flexible pavement was carried out using data from the DIY
Public Works Office of Housing and Energy Mineral Resources (PUPSDM DIY).
The method used in this research is mechanistic-empirical method of KENPAVE
program with elastic and viscoelastic modeling. For alternative pavement design
using Bina Marga 2017 method. The results showed that the existing pavement was
not able to withstand the traffic load during the 10-year plan life, so an alternative
design was needed. Two alternative pavement thickness designs based on the Bina
Marga 2017 method are asphalt pavement with graded foundation layer and CTB.
On the existing pavement, elastic modeling has a longer service life than
viscoelastic modeling. The first damage that occurs is permanent deformation,
followed by rutting and fatigue cracking. Meanwhile, the alternative pavement
proved to be able to withstand the traffic load during the plan life well. Analysis on
alternative pavement shows that elastic modeling has better pavement performance
than viscoelastic modeling, with longer service life in resisting damage.
