Investigation of Physical and Chemical Properties in RAP Materials

The usages of reclaimed asphalt pavement (RAP) are increased at many countries. Behavior of RAP has to be changed into influence of rap on virgin binder which is investigated under mechanical and chemical properties. In this study, Fourier transformation infrared spectroscopy (FTIR) was used to identify the concentration level of chemical bond. Hot mix asphalt design was conducted for various percentages of reclaimed asphalt pavements such as 20%, 30%, and 40%. The optimum binder content was chosen from Marshall test for each set of sample series. Extracted and recovered binder in the optimum asphalt mixture for each sample set was analyzed using FTIR spectrophotometry technique. Concentration levels of carbonyl and sulfoxide bond were converted to an index value which was increased with increments of RAP percentage. However, 20% of reclaimed asphalt pavement would be recommended as per experimental results for road construction as a sustainable green solution of construction practices.
