Effective Utilization of Reclaimed Asphalt Pavement by Using Rejuvenator in Stone Matrix Asphalt for Wearing Course

Pallavi C Hulageri | Anusha T M [2] | H S Jagadeesh [3]

Abstract: Stone Matrix Asphalt (SMA) is a gap-graded asphalt mix which provides high rut resistance to the permanent deformation during its service life. SMA consists of 70-80 % course aggregates, 8-12 % filler, 6-7 % binder and 0.3 % fibre. The higher percentage of course aggregates and bitumen makes the SMA construction costlier. In order to make SMA mix economical Reclaimed Asphalt Pavement (RAP) consisting of aggregate and bitumen can be used for SMA mix. In the present study an attempt has been made on the use of RAP materials for SMA mix with waste engine oil as rejuvenator. A RAP replacement were carried out in varying percentages with and without rejuvenator and laboratory test including Marshall Stability was conducted to find the optimum RAP replacement. Performance tests were carried out for optimum RAP replacements. From test results RAP with rejuvenator showed improved performance characteristics compared to RAP without rejuvenator.
