| Summary: | Pure bitumen production through crude oil petroleum refining process is not
desirable in road pavement application. The asphalt binder exhibits insufficient properties for
pavement construction and need to be modified with various additives. In this study, the effect
of untreated and treated waste cooking oil (WCO) on voids properties of hot mix asphalt was
evaluated. A 5% of WCO (by weight of binder) was selected and replaced into the modified
binder before being mixed with the aggregates in asphalt mixture. The voids characteristic of
hot mix asphalt was determined based on Marshall Mix design test. Five different content of
bitumen i.e. 4%, 4.5%, 5%, 5.5% and 6% was chosen on the basis of min and max value as
required by Malaysia public work department. Test results show that the voids filled with
bitumen and density was increase as the bitumen content increases from 4% to 6% for
untreated and treated WCO mixes. Furthermore, the result also indicates that the void in total
mix was linearly decreased when the bitumen content increased from 4% to 6%. |
