Abstract

The trend nowadays is to reduce the consumption of energy and reserve natural resources. Using Reclaimed Asphalt Pavement (RAP) is considered as an economical and environmental friendly process. This work assesses the prospects of using liquid asphalt (cutback and emulsion) as rejuvenation agent for pavement recycling. Asphalt concrete mixture obtained from site as rubblized binder course was tested for its existing physical properties, then rejuvenated with medium curing cutback or cationic emulsion. Specimens have been prepared from the rejuvenated mixture and tested for Marshall Properties, temperature susceptibility, and moisture damage. Test results were compared with those of aged mixture. It was concluded that the temperature susceptibility decreases by (9 and 24) % for cutback and emulsion treated mixtures as compared to added mix. Marshall Stability decreases by (11 and 15.5) % while the tensile strength ratio increases by (23 and 28) % for cutback and emulsion treated mixtures as compared to added mix. The bulk density increases by (1.8 and 1.1) % while the total volume of voids decreases by (6.5 and 5.3) % for cutback and emulsion treated mixtures as compared to added mix. The indirect tensile strength at 25 °C is lower than that of aged mixture by (11 and 21.5) % for cutback and emulsion treated mixtures respectively.
