CONTRIBUTION OF POLYPROPYLENE FIBERS IN MODIFICATION OF VG 30 BITUMINOUS MIX

Road transportation sector plays a pivotal role in accessing the growth of any country. In developing nations like India, where the traffic development and axle loading is developing at logarithmic scale, weakening of roadways is quick before their future on account of adaptable flexible pavement. The researchers and designers are continually attempting to enhance the execution of bituminous mixtures. In this concentrate, at first bituminous mixtures samples were readied at the ideal bitumen content. To the acquired bitumen content polypropylene fibers in extent of 4%, 5% and 6% are added to assess the volumetric properties of Marshall Mix design. It was observed for fiber - reinforced specimens that the Marshall Stability values increased and flow values red uced in a recognizable way. The change of the properties of bituminous mixture shows the constructive outcome of polypropylene fibers. In this manner, it is presumed that the utilization of polypropylene fibers changes the attributes of bituminous mixtures in an exceptionally helpful manner.
