Abstract
AbstractThe paper presents research results on the Hamburg wheel tracking test (HWTT) of asphalt concrete using RFCC. RFCC (Residue Fluid Catalytic Cracking) is waste from the oil refinery. RFCC is used as filler powder in the hot mix asphalt. Tests for rutting resistance were performed following AASHTO T312:2004 and EN12697-33. Dense graded asphaltic concrete of the nominal maximum aggregate sizes of 12.5 mm with and without RFCC as filler powder was tested using HWTT. The rutting resistance properties of asphalt concrete using RFCC are compared with conventional asphalt concrete using limestone powder. Experimental results show that RFCC can help asphalt concrete improve its resistance to rutting.KeywordsRFCCHMAFiller powderHWTTRutting resistance
