Rheological properties of modified binder incorporating coconut char

Coconut char derive from coconut shell is a waste product that is anticipated to be potential alternative for modified binder. Coconut char has great potential to be used as the base material for modifier because it is safe to use. In this study the coconut char was used as additive in asphalt modif...

It also found that modified bitumen samples enhanced the rheological properties of the bitumen in terms of fatigue cracking and rutting. 2022 Conference or Workshop Item PeerReviewed Mamat, Rosmawati and Hainin, Mohd.
