Performance of modified cold dense graded asphalt mix using oil palm fruit ash (OPFAsh)

Abstract

A lot of research has been conducted in order to investigate other alternative material as a modifier in asphalt mixtures whether for hot mix asphalt or cold mix asphalt. This thesis presents a study of laboratory evaluation on the performance of modified cold dense asphalt mix by incorporating the kerosene, diesel and fine oil palm fruit ash. The aggregates gradation considered in this investigation is dense graded (asphaltic concrete with 14 mm nominal maximum aggregate size- AC14). Laboratory trials were conducted to investigate the performance of modified cold dense graded asphalt mix using OPFAsh in modifying the asphalt binder. The Marshall properties of asphaltic concrete pavement were determined by carried out a series of test to the prepared samples with or without OPFAsh. The performances of resilient modulus also was conducted. Samples have been divided into two types which are controlled samples and modified samples (consist OPFAsh). For each modified samples the percentages of OPFASH were varied from 5, 10 and 15 %. The parameter value results for each samples will compared with the specification SPJ/JKR/2008. The results show that the strength of resilient modulus will increase with increasing of the percentage of bitumen content. Nether less, the result for the Marshall test full fill all the specification except for the stability parameter.
