چکیده
|
This paper presents the results of an investigation carried out on the properties of porous asphalt mixture that are prepared by using granite aggregate and coconut shell. four coconut shells (cs) as substitutes for conventional coarse aggregate were considered in the study: 0%,10%,30%,and 50% by weight of volume. the porous asphalt properties are characterized by voids in total mix,voids in filled bitumen,stability,abrasion loss,binder drainage,and permeability. in addition,the noise reductions of porous asphalt mixture were identified through impedance tube test. the results of the tests showed that coconut shell cannot be satisfactorily used as an aggregate replacement material in order to increases the properties of porous asphalt. however,in comparison between coconut shell replacement levels,10% cs showed excellent performance. on the other hand,the incorporation of coconut shell in porous asphalt mixture has significantly reduces the traffic noise coefficient. © 2016 penerbit utm press. all rights reserved.
