Utilisation of Sisal Fibre in Stone Matrix Asphalt

Abstract

The purpose of this study is to study various engineering properties of SMA mixes by use of sisal fibre. In SMA sisal fibre has not been used before this attempt is made. Here SMA mixes are prepared using sisal fibre with varying binder content and their properties and behavior is found out. In preparations of all samples cement is used as filler and 60/70 bitumen is used as binder. Test method used is Marshall Test. By analyzing tests it is learnt here that sisal fibre may also be used in preparation of SMA mixes. For mild values of traffic sisal fibre would result in a good replacement of conservative fibres because of its low flow value with binder content. Also with consideration of VMA, VFA, VA, and optimum binder content sisal fibre comes to be a good fibre to be used in SMA.
