| dc.description.abstract | Road is the infrastructure used to cross that is very necessary to reach various regions. The
Sentolo-Nanggulan-Dekso road section used as a route of the Borobudur National Tourism Strategic
Area. In 2021 based on a direct survey, there was an increase in traffic volume of heavy vehicles up
to 15.94% of the total volume, where according to traffic data in 2019 only 7.82%.
To improve and develop road performance, a pavement planning and design approach is
needed. This research was conducted to determine alternative flexible pavement thickness using
Mechanistic – Empiric method with Bina Marga 2017 and Kenpave program to obtain the most
suitable alternative pavement.
The existing pavement has total thickness of 50 cm and can accommodates load repetition
until damage occur below than life plan which is 20
th
. Alternative pavement resulted 2 alternatives,
alternative 1 has total thickness of 54.5 consisting of AC WC 4 cm, AC BC 6 cm, AC Base 14.5
cm, and Class A foundation 30 cm. Alternative 2 has total thickness of 47.5 cm consisting of AC
WC 4 cm, AC BC 6 cm, AC Base 7.5 cm, CTB 15 cm, and class A aggregate foundation of 15 cm
thick. With viscoelastic model alternative 1 can accommodate load repetitions of 20,472,951.01
ESAL until rutting, and alternative 2 is 18,559,551.33 ESAL until rutting. With linear elastic model
alternative 1 load repetition is 49,261,433.02 ESAL until rutting, and alternative 2 is 24,415,302.83
ESAL until deformation, where both alternatives can accommodate load repetitions up to the design
life. | en_US |
