EFFECT OF USING FILLER PARTICLES RUBBER MODIFIED ON PAVEMENT RESISTANCE

Additives are commonly used by many constructions. It can reduce pollution and benefit a developing circular economy and binding properties. Rubberized Hot Mix Asphalt (HMA) is more elasticity than (HMA) mad from conventional (HMA). It also shows a greater resistance to aging, crack, rut, and skid. Laboratory tests performed to assess the engineering properties, to determine the stability and resistance to plastic flow of bituminous mixtures using the marshal apparatus. The results were compared with experiments of marshal with %0 ,10%,!5%,and20%,25%,30% rubber ,second test we determine the stability and flow from filler with rubber Versus (vs),and without rubber. The rate of filler and Asphalt was 5%. Then results were compared .The authors found that the rubberized asphalt is more effective with surface resistance, than conventional pavement. The authors notice that the best percentage rubber was 25% on this percentage stability increased at first, and then decreased, when reached the optimum %AC, also the flow increased while increasing %AC. The reason for failure of use filler with rubber, first reason asphalt is absorbed by the rubber particles, second reason use filler that passing sieveN#200.The solution is using a particles larger size, than finer size of rubber
