    Investigating the Effect of Viatop Plus AD 10 Fiber on Moisture Sensitivity and Potential Asphalt Drain down from Stone Mastic Asphalt Mixtures
    Author(s): Sepehr Saedi*, Seref Oruc and Golnar Sadeghian Asl

    Because of the gapping in their gradation and the high bitumen content, the SMA have a high potential of asphalt drain down. Using cellulosic fibers is one of the solutions for this problem. To conduct the study, 38 Marshall non-fibrous samples containing 0.3, 0.4, 0.5, 0.6 and 0.7 weight percentage mixtures of Viatop plus were designed and prepared by Marshall design method. Based on the results, use of 0.5% of fibers with an optimum asphalt content of 6.85% is the optimum amount of fiber used to prevent asphalt drain down. In addition to decreasing the drain down rate below the range determined in the relevant regulations, The Marshall quotient index experienced a maximum amount of 296.66 kg/mm and shows a growth of 22% comparing to non-fibrous samples. However, with increasing amount of fiber, in spite of decreasing asphalt drain down potential, the Marshall quoti.. Read More»
