Study on Adhesive Characteristics of RFCC Asphalt Mastic

The subject of the investigation is the adhesive qualities of asphalt mastic produced by residue fluid catalytic cracking (RFCC). Recycling RFCC, industrial waste from refineries, in asphalt mastic may change the adherence of the asphalt binder. This study investigates RFCC filler affecting the bonding interface between asphalt mastic and smooth solid surface and aggregates. The adhesive properties of RFCC asphalt mastic were investigated through various laboratory tests, including an adhesion test according to TCVN 7504:2005, a modified pull-off test, and the Vialit plate shock test. The article uses experimental data to compare the adhesion properties of RFCC asphalt mastic to conventional fillers like limestone and Portland cement. The results show that RFCC asphalt mastic exhibits good adhesive properties under various surface roughness.
