A Study on the Use of Polypropylene Fibers in Steel Slag Asphalt Mixtures Majid Amoochi m amoochiforooshani@cv iut ac ir Date of Submission 2012 02 08 Department of Civil Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisors S M Abtahi B KooshaAbstractSteel Slags are the by product of iron and steel factories that usually tump in largelandfills around these factories Along the years widespread researches have been donearound the world to use this material in several fields One of these fields is pavementengineering specially Asphalt Concrete AC that can yearly consume a large volume ofslags The studies show that AC containing steel slag have some disadvantages in spite ofdifferent privileges One of the most important of them is the higher optimum bitumencontent in comparision with conventional asphalt concrete This concept increases thetotal cost of slag asphalt concrete and decreases the tendency of investors for the use ofsuch product In this study it is tried to decrease the optimum bitumen content of slag asphalt concreteby reinforcing with polypropylene fibers The results of experiments show that betweendifferent samples bitumen mixtures containing 2 percent of 19 mm polypropylene fibershave the most appropriate performance Presence of fibers in slag asphalt concrete causesa decrement in optimum bitumen content and increment in Marshall stability Keywords Steel Slag Slag Asphalt Polypropylene fibers Asphalt Reinforcment
