The Effects of Different Binders on Mechanical Properties of Hot Mix Asphalt

To determine the behavior of hot mix asphalt including different penetration grade bitumen has been a major subject of paving engineering. In this study the effects of different penetration grade binders on the mechanical properties of hot mix asphalt were investigated with four different tests. The specimens prepared with AC-5, AC-10, AC-20 and SBS modified AC-10. The stiffness modulus, creep stiffness, retained tensile strength and Marshall stability tests were carried out. The objective of the study was to assess the specimens exhibited prepared with different penetration grade asphalt and whether the binder with different penetration grade had the same impact on the different tests. On all tests the mixes prepared with modified AC-10 binder appeared to perform the best when compared with the others and it was determined that the specimens prepared with different penetration grade asphalt exhibited different performance among the tests.
