Dear Nadeesha Maduwanthi Hettiarachchi

We did some researches about asphalt mixtures. Asphalt mixture due to bitumen used in its matrix is a highly temperature depended material. At the high temperatures asphalt mixtures shows viscoelastic behavior and at a low temperatures asphalt mixtures shows a linear elastic behavior. At the low temperature conditions thermal cracking becomes to the main distress of asphalt mixtures. For preventing and minimizing cracks in asphalt mixtures researchers were used some modifiers (Polymers, Rubbers, Nanomaterials, Fibers, etc.). We used some type of nanomaterials (Nanotubes, Fe2O3, Al2O3, Montmorillonite, and Nano silica) and Fibers (Kenaf, Goat wool, Carbon, Glass, and Basalt) for improving the resistance of asphalt mixtures against crack occuring. Our Results showed that all type of modifiers increase the resistance of asphalt mixtures against low temperature cracking from 10% to 46%(based on type of modifier and optimum content of it). For more details about asphalt mixtures, I recommended you to read my works.
