Abstract: Bituminous mortar, also known as fine aggregate matrix in North America, consists of bitumen, filler and fine aggregates. This research is to investigate the effect of ageing on the chemical and rheological properties of bituminous mortar and its reclaimed bitumen and apply it in further study of blending efficiency of bituminous mortar. The aged bituminous mortars include one type with base bitumen from field and the other with Styrene-Butadiene-Styrene (SBS) modified bitumen aged artificially in the laboratory. Cylindrical specimens were prepared and their complex shear modulus and shear fatigue life were characterized through the Dynamic Shear Rheometer (DSR) tests. After that, reclaimed binder from the mortar were tested through FTIR for determining their chemical properties.
