| dc.description.abstract | Boja - Darupono road has a length of 12,85 km in Kendal Regency. The
increasing volume of traffic in Kendal Regency, which can be seen from the
percentage of annual population growth rate of 1.2% and population
density of 1016 per km2
, can cause road pavement to experience damage
to grooves, cracks, and holes in the road body. This study aims to determine
the level of damage to the road surface and its repair, as well as to
determine the thickness of the overlay layer and determine the stress strain
value to get the remaining service life of the pavement. The data used in the
research on the Boja Darupono Road Sta. 10+200 - Sta. 11+500, namely
primary and secondary data, primary data in the form of data taken directly
in the field in the form of measuring the area and type of damage with the
PCI method. While secondary data obtained from DPUPR Kendal Regency
in the form of pavement data, LHR data and soil CBR data. The research
was conducted using PCI, Bina Marga 1987, Bina Marga 2017 and
Empirical Mechanistic methods with the KENPAVE program. Based on the
research that has been done, the PCI value of 48,692 is included in the fair
road condition. Calculation of overlays using the Bina Marga 1987 method,
the minimum thickness of the overlay is 13 cm. The KENPAVE program is
used to obtain the stress strain value, so that the repetition load on the
existing pavement conditions is 292831,6939 ESAL until fatigue cracking
occurs, 564189,1287 ESAL until rutting occurs, and 1046040,596 ESAL
until deformation occurs. In the condition of the overlay pavement, the
repetition load is obtained at 82473737,82 ESAL until fatigue cracking
occurs, 4707863,254 ESAL until rutting occurs, and 7973182915,1572
ESAL until deformation occurs. It can be seen that with the addition of
overlays on the pavement, the repetition load can increase so that the
planned life of the pavement can be fulfilled. The results of the 2017 Bina
Marga method analysis obtained the remaining life value for the overlay
pavement in year 2 (2025) is 82,06%. | en_US |
