• Abstract:
  In recent years, the use of reclaimed asphalt pavement (RAP) as a component of asphalt mixtures has ; become a common practice. For many years, researchers and DOT officials have questioned the adverse ; effects, if any, of using solvents to extract and recover the binder. Therefore, researchers have been ; investigating new methods, without extraction techniques, of estimating the RAP binder properties, ; especially with respect to the low-temperature characteristics of binders and the mixtures. The major ; goal of this research project was to determine if the low-temperature properties of the aged asphalt ; binder in RAP could be obtained by using the fines (-#50 to +#100) generated from sieved RAP ; materials rather than from the binder extracted from the RAP. In addition, the low-temperature ; characteristics of several mixtures containing RAP were studied and evaluated for any correlation with ; the binder properties. Several samples were made with different RAP sources, different percentages of ; RAP content, various low temperatures (i.e., 0, -6, -12, and -18 °C), and at many states (i.e., virgin, ; RTFO, and PAV). In addition, some of the RAP sources were obtained after one year and BBR testing ; was conducted. Other testing procedures and specifications such as indirect tensile strength and semicircle ; bending (SCB) were used and evaluated.
