Statistical Analysis of Stone Mastic Asphalt Incorporating Kenaf Fibre

Stone mastic asphalt consists of two components coarse aggregate and bitumen-filled mortar (bituminous blend, filler, stabilizing additives like cellulosic or mineral fibers). Such a form hot mix (SMA) was first developed in Germany the mid-1960s to cope with corrosion ribbed wheel destruction. The mixture then known as stone asphalt, which not only immune wheels but also has strong resistance against rutting. One most significant problems when constructing pavement is permanent deformation. By load traffic strain tires, much irreversible deformation happens ground. According previous study, researchers have stated that kenaf fiber's physical strength thermal characteristics are superior compared other forms natural fiber polymer composites, therefore deemed desirable applicant for elevated-performance composite materials. Thus, aim this study assess mechanical performance incorporating by developing regression model. A set data SMA various percentages were assessed through statistical analysis Minitab 19 using resilient modulus dependant variable model accumulated from dynamic creep test second models showed positive impact an additive mixture. For more future studies, it recommended analyze effect proportions bitumen modification towards will render satisfactory during service.
