| Abstract | Cirebon – Losari flexible pavement which is located in North Coast of Java, Indonesia, is in the severe damage condition caused by overloading vehicles passing the road. Since there has been a phenomenon of overloading happened in many countries and improvement of material properties quality in flexible pavement design which are not considered in AASHTO 1993, the need for developing improved pavement design and analysis methods is very necessary.
The increment of loads and quality of material properties can be evaluated through Mechanistic-Empirical (M-E) method which is based on elementary physics and determines pavement respond to wheel loads or environmental condition in terms of stress, strain, and displacement. M-E software like KENLAYER has been developed to facilitate the transition from empirical to mechanistic design methods.
From the KENLAYER analysis, it can be concluded that the effect of overloading to the pavement structure performance is difficult to minimize even though the first two layers have relatively high modulus of elasticity. The occurrence of 150%, 200%, and 250% overloading have a very significant effect in reducing 84%, 95%, and 98% of the pavement design life, respectively. If the modulus elasticity of asphaltic concrete decreases to the lower bound, the design life decreases 32%, while if the modulus elasticity of cold milling recycling foam bitumen decreases to the lower bound, the design life decreases only 9%. In the contrary, if the modulus elasticity of asphaltic concrete increases to the upper bound, the design life increases 125%, while if the modulus elasticity of cold milling recycling foam bitumen increases to the upper bound, the design life increases only 51%. For the purpose of increasing the pavement service life, it is more effective to limit and manage the allowable load than to improve the pavement materials. |
