ABSTRACT

Some pavements at airport facilities that suffered damage before the planned service life were mainly on the apron. Several design parameters, such as material quality, CBR subgrade, and annual departure, influence the service age of the hardening. This research aims to compare the service life to the changes in design parameters during rigid pavements of the apron. The method used is Federation Aviation Administration AC 150/5320-6G with FAARFIELD V 2.0.18 software. The analysis was carried out with alternative measures of decreased concrete plate material quality, decreased CBR Subgrade, and increased annual departure. Based on the results of the research, the model for the change of conditions from 0 - 50% to service life on the CBR subgrade is y = 20.239e−0.008x, on the annual departure is y = 19.832e−0.006x, and on the quality of concrete slab material is y = 25,165e−0.119x. The quality of the concrete plate material is the biggest design parameter that causes a change in service life compared with other design parameters because it has the largest exponential value (reduction life service).
