EVALUASI TEBAL PERKERASAN LENTUR MENGGUNAKAN PROGRAM KENPAVE DI JALAN MAOSPATI-SUKOMORO
Abstract
The mechanistic-empirical method is one of the techniques used in the
design of pavement thickness. Maospati-Sukomoro Road is the primary access to
Magetan City which is traversed by heavy vehicle traffic. This study was conducted
with the aim to design the pavement thickness and to analyse the pavement
performance against fatigue cracking and rutting. Bina Marga 1987 and AASHTO
1993 were used as the empirical method in this research. The results then analysed
with Kenpave program as the mechanistic method. The calculations showed that the
Bina Marga 1987 produce Nd value of 7.52 x 105 and Nf value of 5.77 x 1012
whereas the AASHTO 1993 produce Nd value of 2.12 x 109 and Nf value of 1.42 x
1011. The result shows that the designed pavement thickness using Bina Marga 1987
method is unable of serve the planned traffic load and will be damaged if there is
no immediate maintenance work. While the AASHTO 1993 method is able to serve
the planned traffic load.
