Interface bond and compatibility of jute with asphalt

With a view to investigating compatibility of jute with asphalt and deriving an insight into their interfacing bond, samples of pure asphalt as also fiber–asphalt, yarn–asphalt and fabric–asphalt composites were prepared and subjected to tensile tests. The nature of interface bond was sought to be understood through changes in tensile properties of fiber–asphalt composites vis-à-vis tensile properties of pure asphalt sheet while the role played by reinforcement materials was revealed by the tensile behavior of yarn–asphalt and fabric–asphalt composites. As a result it is observed that the extent and uniformity of encasement as also the extent of penetration of substrate by the asphalt material are instrumental in determining tensile properties of the composite. The tensile rupture behavior of the composites was assessed through analyzing the crack line across the width of the composites.
